The West Indian Manatee
Manatees are large plant-eating slow moving aquatic mammals. Short front flippers help them steer or even crawl through shallow waters and strong paddle-shaped tails propel them.
A distant relative of the elephant they have thick, wrinkled skin that is grey or brown in color. An average adult is about 10 feet long and weighs between 1,500 and 2,200 pounds with a life expectancy of about 50-60 years.
The major threats to manatee survival are human activities: boat-related injuries and deaths, habitat loss or degradation, and in some countries, hunting.
The U.S. Geological Survey works in partnership with other Federal and State agencies and private organizations to study manatee life history, behavior, ecology, and population biology.
