West Indian manatees are large, gray aquatic mammals with bodies that taper to a flat, paddle-shaped tail. They have two forelimbs, called flippers, with three to four nails on each flipper. Their head and face are wrinkled, with whiskers on the snout. The manatee’s closest relatives are the elephant and the hyrax (a small, gopher-sized mammal).

Manatees are believed to have evolved from a wading, plant-eating animal. The West Indian manatee is related to the African manatee, the Amazonian manatee, the dugong, and Steller’s sea cow, which was hunted to extinction in 1768. The average adult manatee is about 10 feet long and weighs between 800 and 1,200 pounds.

Manatees can be found in shallow, slow-moving rivers, estuaries, saltwater bays, canals, and coastal areas—particularly where seagrass beds or freshwater vegetation flourish. Manatees are a migratory species. Within the United States, they are concentrated in Florida in the winter. In summer months, they can be found as far west as Texas and as far north as Massachusetts, but summer sightings in Alabama, Georgia and South Carolina are more common. West Indian manatees can also be found in the coastal and inland waterways of Central America and along the northern coast of South America, although distribution in these areas may be discontinuous.

Manatees are gentle and slow-moving animals. Most of their time is spent eating, resting, and traveling.

Manatee are mostly herbivorous; however, small fish and invertebrates can sometimes be ingested along with a manatee’s normal vegetation diet. They eat aquatic plants and can consume floating, emergent, and submerged vegetation from freshwater, brackish, and saltwater environments.

Because they are mammals, they must surface to breathe air. They may rest submerged at the bottom or just below the surface of the water, coming up to breathe on average every three to five minutes. When manatees are using a great deal of energy, they may surface to breathe as often as every 30 seconds. When resting, manatees have been known to stay submerged for up to 20 minutes.

Manatees can swim up to 20 miles per hour in short bursts, but they usually only swim about three to five miles per hour.

Manatees are capable of living long lives. In fact, it is possible for manatees to live up to 60 years or more. Because of the many perils in the wild, however, longevity is uncertain. In particular, research conducted at the Florida Fish and Wildlife Conservation Commission shows cause for concern. This research revealed that few manatees were living past the age of 30, and the majority of animals that were necropsied died between the ages of 0 and 10—nowhere near their estimated life expectancy of 60 years.

Researchers have isolated several causes of manatee deaths, most of which are directly related to human contact or encroachment. If these sources of mortality are not controlled, manatees may become extinct.

Scientists break down the causes of manatee deaths into six different categories:

  • Watercraft Collisions: Manatee mortalities caused by the crushing impact of the hull and/or slashing of the propellers. In the case of large power vessels and barges moving through shallow waters, manatees may be caught between the vessel and the water bottom or between the vessel and a docking structure and crushed. Watch our videos: In Danger on the Water and Manatees and Watercraft
  • Flood Gate or Canal lock: Manatee mortalities caused when the animal is crushed and/or drowned in these structures.
  • Other Human-Related: Manatee mortalities caused by monofilament line, fishing nets, fishing hooks, litter, poaching, or other human activities. Watch our video: Manatees and Entanglement
  • Perinatal: A dependent calf less than 150 cm (about 5 feet) that died around the time of birth and was not determined to have died from human-related causes.
  • Other Natural: Mortalities caused by natural circumstances such as cold stress, red tide, gastrointestinal disease, pneumonia, and other diseases.
  • Undetermined: The manatee is too badly decomposed to determine cause of death, the necropsy finding is inclusive, or the manatee carcass was reported and verified, but not recovered.

A manatee’s age can be determined by the annual growth rings in its ear bones. Living manatees are classified as calves, subadults, and adults, and age can be approximated by birth date (if known) and their size. Learn more about estimating manatee age using growth layer groups in ear bones.

Manatees do not form permanent pair bonds like some animal species. During breeding, a single female, or cow, will be followed by a group of a dozen or more males or bulls, forming a mating herd. They appear to breed indiscriminately during this time; however, the age experience of some males in the herd probably plays a role in breeding success. Although breeding and birth may occur at any time during the year, there appears to be a broad spring-summer calving peak.

The reproductive rate for manatees is low. Manatees are not sexually mature until they are about five years old. It is believed that one calf is born every two to five years, and twins are rare. The gestation period is about a year. Mothers nurse their young for one to two years, during which time a calf remains dependent on its mother.

Males assume no responsibility for raising the calf. Mothers nurse their young for one to two years, so a calf may remain dependent on its mother during that time. Calves nurse underwater from teats located behind the mother’s flippers and begin to eat plants a few weeks after birth. Newborn manatee calves are capable of swimming to the surface on their own and vocalize at or soon after birth.

Female manatees usually seek quiet areas in which to give birth. In Florida, newborn calves can be seen at any time of the year, although more seem to be born in the spring and summer.

Most births are of a single calf about 120 centimeters (about 47 inches) long and weighing 30 kilograms (66 pounds), although a few cases of twins have been documented. The details of the birth process remain unclear but observations of calving in captive manatees have shown that the offspring can be born either head- or tail-first.

In the few cases in which births have been observed in captivity, the newborn calf is capable of swimming to the surface on its own, although the attentive behavior of the mother may give the impression that she is assisting the calf. Calves vocalize at or soon after birth and this is probably an important part of the mother-calf bonding process.

The calf begins to nurse within a few hours after birth, and nursing frequency and duration increases as the calf becomes more proficient. Calves nurse underwater from teats located behind the mother’s flippers and begin to eat plants a few weeks after birth.

Manatee calves vocalize at or soon after birth — an important part of the mother-calf bonding process.

The precocious calves are able to swim with their mothers within minutes of birth. A young animal commonly remains close to its mother’s side. Adult manatees typically swim in single file, but a calf always travels parallel to its mother, directly behind her flipper. It is possible that the animals can communicate most effectively in this position, or the formation is advantageous if the calf experiences less draft from the water.

Female manatees do not attack other manatees or humans that approach their young. Instead, they attempt to keep other manatees and human divers away from their calves by swimming between the intruder and their offspring. If the danger is perceived as severe, the female and calf will flee. A fleeing female – calf pair produces a duet, with one animal vocalizing and the other emitting an answering call.

A manatee calf may stay with its mother for one to two years, even though it is probably nutritionally independent by the end of its first year. The calf gets information on feeding and resting areas, travel routes and warm water refuges from its mother.

Manatees emit sounds underwater that are used in communicating with one another. These sounds can be described as chirps, whistles, or squeaks. It is not believed that they are used for navigational purposes. Vocalizations may express fear, anger, or sexual arousal. They are also used to maintain contact, especially when manatees are feeding or traveling in turbid water. Most common are vocalizations between mothers and calves.

Common Manatee Sounds

Manatees communicate by using calls that have been described as squeaks, chirps, or grunts. The way the call sounds depends on the situation and the reason the manatee is communicating.

Frustrated or Annoyed Manatee

It's true! Manatees get upset, too. Listen and see if you can tell how a manatee's call changes when he or she is frustrated or annoyed.

Frightened Manatees

Have you ever screamed when you were startled or scared? Well, manatees do the same thing. In this segment, a group of manatees are frightened by a boater.

Calls Between a Mother and Calf

Usually, manatees are quiet animals. But moms and calves provide location information by calling back and forth. Listen to the difference in pitch between the two animals.

Nursing Calf

Just like you nag your mom for snacks, manatee calves make squeaking sounds until they are allowed to nurse from the nipples located behind their mother’s flippers.

Calf Searches for Mom

"Quit playing and get over here!" That's what a manatee mom might mean when she calls to her calf. She may want to leave an area or she senses danger. When calves can't find their moms, they will cry loudly until she answers. After locating their mother, they swim to her side. When Lucille, one of the manatees in our Adopt-A-Manatee program, was less than one year old, her cries were recorded when she became separated from her mom.

Mechanical Sounds

What? Are manatees mechanics? No, these are sounds that help manatees know another manatee is present. Listen to a manatee rising to breathe, the swirling of water during a sudden movement, a manatee feeding on aquatic plants, and -- yes, it's true -- the sound of flatulence produced during digestion. Hmm, manatees and humans are very similar in some respects!

As of the most recent aerial surveys in January – February 2019, there are at least 5,733 manatees in Florida. These aerial surveys are flown over manatee aggregation sites during the winter months when manatees gather in high numbers.

Since the surveys started in 1991, the number of manatees counted during the surveys had increased, which is related to a growing population, improved survey techniques, and increased knowledge of where manatees aggregate. Synoptic survey counts do not provide statistical estimates of population size and thus are not supposed to be used to determine trends in the population. Rather, these surveys provide a minimum count of manatees. The outcome of the survey is highly dependent on weather conditions and factors including wind speed, glare, and water clarity (turbidity) affect the ability of researchers to count manatees, while the severity of the cold front determines just how many manatees are present at the warm water site to be counted [1].

The manatee population in Florida is divided into four management units (Northwest, Upper St. John’s River, Atlantic, and Southwest). Runge et al. (2007) noted that the population of all four units is likely to decrease over the next few decades with the loss of warm water refuges [2]. In 2017, the U.S. Fish & Wildlife Service issued its final rule to downgrade the status of the West Indian manatee from endangered to threatened under the federal Endangered Species Act despite the fact that the best available scientific data and legal standards indicate that downlisting at this time is inappropriate.

In spite of their size, manatees have relatively little body fat, and their metabolic rate is low compared to other marine mammals. Manatees cannot tolerate temperatures below 68° F (20° C) for long periods of time. Researchers believe that individuals affected by the cold cannot produce enough metabolic heat to make up for heat loss in the environment.

Because of their susceptibility to the cold, the space or range that manatees require is influenced by seasonal change. Florida manatees are considered to be somewhat migratory animals.

In the summer months, manatees travel freely around Florida’s rivers and coastal waters. A few manatees may range as far west as Texas and as far north as Virginia (manatees have even been documented in Cape Cod, Massachusetts!), but these sightings are rare. Sporadic summer sightings in Alabama, Georgia, and South Carolina are relatively common.

Range of the Florida Manatee

In the winter, usually November through March, the manatee population is concentrated primarily in Florida. Water temperatures that fall below 70° F (21° C) cause manatees to move into warm-water refuge areas. Scientists don’t know what cues manatees follow, but they seem to know when cold weather is coming and seek warm-water areas.

Travel corridors, or passageways, are necessary for manatees to move back and forth between summer and winter habitats or between feeding and resting or calving areas. It has been documented that many manatees have preferred habitats they return to each year.

Warm-Water Gathering Areas

When the weather cools down, manatees gather near natural springs such as Blue Spring on the east coast of Florida or in the Crystal or Homosassa Rivers on Florida’s west coast. These springs are winter refuges for manatees because the water temperature is relatively constant throughout the year—averaging about 22° C (72° F). When the surrounding waterways get colder, manatees move into the springs to keep warm.

Manatees also gather at warm-water effluents of power plants like the Tampa Electric Company in Apollo Beach or Florida Power & Light Company in Ft. Myers or Riviera Beach. Power plants have probably extended the manatee’s winter range. At one time, researchers believe, manatees only ranged south of Sebastian Inlet and Charlotte Harbor in the winter. As coastal development pressures in southeast and southwest Florida have pushed manatees further north, power plant effluents have played a critical role in manatee protection.

Unfortunately, warm-water sources for manatees are at risk of disappearing as aging power plants go offline and spring flows are affected by Florida’s growing human population and its water needs. Such loss of warm-water habitat could result in catastrophic manatee die-offs during cold winters. The maintenance of warm-water refuges will be an important factor in the manatee’s future survival potential. We need to make sure that spring flows are maintained and devise warm-water alternatives before power plants go offline.

West Indian manatees in the United States are protected under federal law by the Marine Mammal Protection Act of 1972, and the Endangered Species Act of 1973, which make it illegal to harass, hunt, capture, or kill any marine mammal.

West Indian manatees are also protected by the Florida Manatee Sanctuary Act of 1978. Violations of these federal or state laws can be met with civil or criminal convictions associated with monetary fines and/or imprisonment.

The Florida Manatee Recovery Plan was developed as a result of the Endangered Species Act and is coordinated by the U.S. Fish & Wildlife Service (FWS).

In October of 1989, Florida’s Governor and Cabinet directed the state’s wildlife agency to work with 13 “key” manatee counties in Florida to reduce injuries and deaths. These 13 counties were: Brevard, Broward, Citrus, Collier, Dade, Duval, Indian River, Lee, Martin, Palm Beach, St. Lucie, Sarasota, and Volusia. Over the years, these 13 county governments have worked with the state to develop site-specific boat speed zones to reduce the likelihood of watercraft collisions and to implement comprehensive manatee protection plans (MPP) for each county.

Other conservation measures deemed important to saving manatees include: research addressing biology, mortality, population and distribution, behavior, and habitat of manatees; implementation of management plans; posting of regulatory speed signs and levying of fines for excess speeds in designated areas; manatee education and public awareness programs; and public acquisition of critical habitat and creation of sanctuaries.

The West Indian manatee belongs to the scientific order Sirenia and the Florida manatee is a subspecies of the West Indian manatee. Other sirenians include the Amazonian manatee, dugong, Steller’s sea cow (extinct), and African manatee. The map below shows the range of each sirenian species and a description of each species is included below.

This map shows the range of each sirenian species.

Outside of Florida, not much is known about the population of West Indian manatees or other sirenians in the world. By far, the largest population of West Indian manatees is found in the United States, primarily in Florida. Elsewhere, they are found in small population pockets throughout their range. All sirenian species in the world are listed as endangered or vulnerable by the IUCN – World Conservation Union.

Members of the extant order Sirenia are found in aquatic habitats throughout the tropics and subtropics. Sirenians are the only completely aquatic mammals that are herbivores. Because of their herbivorous nature, all sirenians are found in relatively shallow waters where sunlight can penetrate and stimulate plant growth.

FAMILY: TRICHECHIDAE

West Indian Manatee

Trichechus manatus

Subspecies:
Trichechus manatus latirostris (Florida manatee)
Trichechus manatus manatus (Antillean manatee)

Florida manatees are found in the southeastern United States, mostly in Florida. Antillean manatees are found in the coastal and inland waterways of eastern Mexico, Central America, the Greater Antilles, and along the northern and eastern coasts of South America. Both Florida manatees and Antillean manatees can be found in salt, fresh or brackish waters and feed on marine, estuarine, and freshwater vegetation.

Amazonian Manatee

Trichechus inunguis

Amazonian manatees are found in the waters of the Amazon River and its tributaries in South America. The smallest member of the family Trichechidae, the Amazonian manatee has smooth skin and no nails on its flippers and feeds on freshwater vegetation.

African Manatee

Trichechus senegalensis

The African manatee is very similar in size and appearance to the West Indian manatee and lives in similar habitat. African manatees are found in African coastal areas, but little is known about this species because they have not been widely studied.

FAMILY: DUGONGIDAE

Dugong

Dugong dugon

Les dugongs se trouvent dans la région Indo-Pacifique du monde. Ils ont une peau lisse et une douve caudale échancrée. Ils se nourrissent d’herbiers marins et sont chassés par les humains pour se nourrir. Les dugongs ont des défenses, mais ces défenses éclatent typiquement à travers les gencives uniquement chez les mâles et restent normalement intactes chez les dugongs femelles.

La vache marine de Steller

Hydrodamalis gigas

À une certaine époque, la vache marine de Steller a été trouvée dans les eaux froides de la mer de Béring, mais elle a été chassée jusqu'à l'extinction dans les 27 ans suivant sa découverte en 1741. La plus grande sirénienne jamais enregistrée, la vache marine de Steller mesurait jusqu'à neuf mètres ( 30 pieds) de longueur et pesait environ quatre tonnes métriques (environ 4,4 tonnes ou 8 818 livres).

Un homme découvre le fond marin. Les hommes sont des mammifères marins de grande taille et de couleur gris.

Les animaux sont des mammifères marins de grande taille et de couleur gris, avec des corps qui sont étendus sur une surface plane, avec une bouteille en forme de cuillère. Tenenen dos aletas, con tres o cuatro uñas en cada aleta. Sus cabezas y caras son arrugadas con bigotes en el hocico.

Les parents terrestres s'intéressent le plus aux manats, à l'éléphant et au dame (un petit mamifero du tamaño d'una tuza). Il semble que les animaux aient évolué à partir d'un animal herbivore semi-aquatique. Le manatí del caribe (lamantin des Antilles, également connu comme le manatí antillano) est lié au manatí d'Afrique, le manatí de l'Amazonie, le dugongo et la vaca marina de Steller (vache de mer de Steller), qui ont dû s'éteindre en 1768. Un homme adulte proche de trois mètres de long et pesant environ 550 kilos.

Habitat et distribution

Les eaux se trouvent dans les eaux llanes, les rivières lentes, les estuaires, les baies d'eau salée, les canaux et les zones côtières – en particulier là où les praderas de hierbas marinas ou les végétations d'eau douce prolifèrent. Les manatíes sont une espèce migratrice. Aux États-Unis, ils se concentrent en Floride et dans l'hiver. Au mois d'été, vous pouvez rencontrer l'ouest jusqu'au Texas et le nord jusqu'au Massachusetts, sans embargo sur les avis en Alabama, en Géorgie et en Caroline du Sud dans la plupart des communes.

Comportement

Los manatíes son animales apacibles y lentos. Le maire partie de son temps se consacre à venir, à découvrir et à parcourir. Les oiseaux sont généralement des herbivores, sans embargo, dans certaines occasions, ils peuvent manger de petites espèces et des invertébrés en même temps que la végétation, ce qui est le régime alimentaire normal d'un homme. Il alimente une grande variété de plantes émergentes, sumergidas et flottantes. Dans un journal, vous pouvez consommer le 10-15% de votre poids corporel dans la végétation.

Debido a que son mamíferos, tienen qui émerge para respirar aire. Ils peuvent descansar sumergidos en el fondo o justement bajo de la superficie de l'eau, llegando a respirar en promedio cada trois a 5 minutos. Lorsque les mains utilisent une grande quantité d'énergie, elles peuvent pénétrer à la surface pour respirer pendant 30 secondes. Au repos, vous savez que les mains peuvent rester en place jusqu'à 20 minutes.

Les manatíes peuvent atteindre une vitesse de 30 kilomètres par heure sur des distances courtes, mais comme d'habitude, elles atteignent une vitesse de 5 à 8 kilomètres par heure.

Espérance de vie, Mortalité et Población

Ils n'ont pas d'ennemis naturels et croient qu'ils peuvent vivre jusqu'à 60 ans ou plus. Comme dans toutes les situations d'animaux sauvages, un certain pourcentage de mortalité chez les humains est attribué à des causes de mort naturelle telles que le syndrome de l'hiver, l'inflammation gastro-intestinale, la pneumonie et d'autres maladies. Un haut numéro de morts supplémentaires est lié à la cause humaine. La plupart des morts de personnes liées au être humain sont produites par des colisiones avec des embarcations en Floride. D'autres causes de mortalité humaine liées à l'être humain comprennent les personnes aplastées et/ou agréées dans les zones fermées et les structures de contrôle des inondations ; l'ingestion d'anszuelos, de basuras, ou de lignes de pêche, et d'enredos dans des lignes de trampas pour les cangrejos.

En fin de compte, la perte d'habitat est l'amenaza la plus grave qui affecte les hommes dans divers pays. Dans l'exemple le plus urgent de l'EE.UU., l'Indian River Lagoon (localisé sur la côte est de la Floride) a subi une série de floraisons d'algues nocives. Les histoires de floraison aboutissent à une perte massive de pâtes marines, ce qui a provoqué des morts de siècles de manatíes qui ne peuvent pas trouver suffisamment de nourriture. Cet événement inhabituel de mortalité des hommes s’est produit pendant la période 2020-2021 et s’est poursuivi aujourd’hui dans la journée.

Créations et reproductions

La tâche de reproduction des lectures est basse. Les hommes ne sont pas des fils sexuels de femmes jusqu'à cinq ans. Il semble qu'une naissance naisse chaque mois de cinq ans, et les jumeaux son peu fréquents. La période de gestation dure 13 mois. Les mères aiment leurs enfants au cours d'une ou deux années, pendant un certain temps, elles dépendent de leur mère.

Protection Légale

En EE.UU., les autorités sont protégées par la loi fédérale sur les espèces en péril de 1973 et la loi de protection des mammifères marins de 1972. Ces lois déclarent illégalement acosar, hacer daño, capturar, o matar un cualquier mamífero marino. Les hommes sont également protégés par la Loi du Sanctuaire pour les hommes de 1978, qui définit l'acoso comme « tout acte intentionnel ou négligent, ou l'omission qui pourrait occasionner un dommage à un homme en colère doit modifier notamment ses patrons de comportement qu'ils reproduisent ». , alimentar, y refugiarse. Les sanctions pénales pour une première infraction peuvent inclure plusieurs mesures jusqu'à $500 et/ou l'incarcération jusqu'à 60 jours.

Au niveau international, toutes les sirènes sont protégées par le protocole de la Convention de Carthagène (SPAW) qui interdit de faire du commerce, de l'achat ou du vendeur, y compris des pièces ou des produits qu'il a choisis à partir des autorités.

COLOMBIE

Au niveau national, les hommes sont protégés en Colombie depuis 1969, par la résolution n° 574 qui interdit la chasse aux animaux en danger. Cette résolution interdit également le transport, la commercialisation et l'utilisation des travailleurs et de leurs produits.

COSTA RICA

Au niveau national, les hommes sont protégés depuis 1953 au Costa Rica. En 1992, la ley de Conservación de la Vida Silvestre no 7315 définit les manatíes comme en peligro.

GUATEMALA

Au niveau national, les hommes furent protégés au Guatemala depuis 1959 avec la création de l'Acuerdo Presidencial déclarant la affaire des hommes illégale. Sans embargo, cette loi a été peu efficace et a été renforcée en particulier en 1981 et en 1989.

MEXIQUE

Au niveau national, les hommes sont protégés depuis 1921 lorsque la affaire a été déclarée illégale. En 1981, il a été interdit la commercialisation de produits similaires à partir de manatíes.

RÉPUBLIQUE DOMINICAINE

Le niveau national des travailleurs protégés depuis 1938 et en 1962 a interdit la vente de produits qu'ils ont fabriqués à partir de travailleurs.

Conservation

La conservation des dirigeants se dirige vers le corps des organisations gouvernementales et non gouvernementales. Les mesures de conservation sont orientées vers cinq thèmes principaux :

  1. L'incrémentation et l'application de la législation en faveur de la protection des hommes à travers les avions de manœuvre et la mise en œuvre de mesures de protection des hommes ;
  2. L'éducation des populations locales aux nécessités de la protection des hommes. Diverses actions sont mises en œuvre dans les directions des pêcheurs pour éviter que cela ne se produise aux mains, mais aussi pour qu'elles s'abattent sur les rescates des mismos. Dans certains pays, ils privilégient également les alternatives économiques d'écotourisme pour compenser le coût des hommes. Plusieurs centres sont organisés pour éduquer les enfants sur l'importance de la protection des hommes. Au Mexique, on célèbre chaque année le jour national du gouvernement le 7 septembre avec diverses activités de diffusion au public.
  3. Développement de projets d'enquête sur l'espèce, pour générer des connaissances sur les dirigeants spécifiques à chaque pays. Les projets actuels concernent notamment des projets pour l'estimation de la population, la télémétrie, des études de comportement telles que la prudence en matière de vie forestière, des études de génétique et d'évaluation de la santé des animaux.
  4. Protection de l'habitat des animaux grâce aux actions locales et à la création de zones protégées.
  5. Les mesures de réhabilitation des animaux domestiques, des enfants ou des hommes à travers les réseaux de restauration, la réhabilitation des animaux et leurs réintroductions, même si cette dernière partie est aujourd'hui mise en œuvre dans quelques pays avec succès.

Fonction de Save the Manatee Club

La mission du Save the Manatee Club (SMC) est de protéger les oiseaux en danger d'extinction et leur habitat aquatique pour les générations futures. Pour enregistrer cette mission, nous travaillons à accroître la conscience publique et l'éducation, à patrouiller les enquêtes, les sauvetages, la réhabilitation et la libération des hommes et à abattre les forces de protection, comme les zones de limite de vitesse pour les bateaux et les sanctuaires. SMC s'occupe également des recherches et de la conservation d'autres espèces de sirènes dans tout le monde.
