West Indian Manateeアメリカマナティー
Trichechus manatusVU— Vulnerable
The West Indian manatee is a large, gentle marine mammal found in coastal waters and rivers from the southeastern United States through the Caribbean to northern South America. A herbivore, it grazes on seagrass and other aquatic plants for several hours a day and gathers in warm-water refuges during colder months. The IUCN lists the species as Vulnerable, with boat strikes and habitat loss among the main threats to its survival.

Species Data
Did You Know?
- Its molars are continuously replaced throughout life in a process called "marching molars," migrating forward at 1 to 2 millimeters per month to replace worn teeth. Source
- Its entire body is covered in sensitive tactile hairs that are thought to function like a fish's lateral line, detecting water movement. Source
- In winter, manatees leave cooling coastal waters and gather in warm-water refuges, including areas near power plant discharge outlets. Source

FAQ
- What do West Indian manatees eat?
- They are herbivores that graze on seagrass and other aquatic and coastal plants, spending five or more hours a day feeding and consuming 4 to 10 percent of their body weight. Source
- How long do West Indian manatees live?
- In the wild they can live 50 years or more, and captive individuals have lived into their late 60s and beyond. Source
- Why do manatees gather in warm water in winter?
- Manatees are sensitive to cold, so during winter they move away from cooling coastal waters and congregate in warm-water refuges, including natural springs and areas near power plant discharge. Source
