With three recognized species, manatees (along with their relative, the dugong) also possess a unique range, limited mostly to coastal bays and waterways of the warm southern coasts. They are also the world’s only herbivorous marine mammals, and they have a highly-developed mouth with bristles. Although much-loved, the manatee population is currently under threat…show more content…
Florida manatees aggregate in warm-water outfalls of power plants (see Figure 3) and natural springs in winter, seeking refuge from the colder ambient waters of surrounding bays, rivers, and estuaries. Aerial surveys that intensively cover manatee habitat in small, well-defined areas, like these winter aggregation sites (Packard et al. 1985), have been useful in obtaining minimum population counts.”[4] 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.[5] The freshwater Amazonian Manatee (T. inunguis) inhabits the Amazon River and its tributaries. Amazonian Manatees never venture into salt water. They are found from the mouth of the Amazon River to the upper reaches of the tributaries of Brazil, Colombia, Ecuador, Guyana and Peru.[6] West African Manatees are found in coastal marine and estuarine habitats and in freshwater river systems along the west coast of Africa from the Senegal River south to the Kwanza River in Angola. Areas included in their ranges are Gambia, Liberia, Guinea-Bissau, Guinea, Sierra Leone, Côte d'Ivoire,
