This and their average speed of 3 to 5 miles per hour means that manatees are way too slow to escape from the path of a speeding boat.

They move along in the water very slowly. Sonar technology is also aiding in the West Indian Manatee conservation. These herbivores munch on food for almost half the day, eating ten percent of their body weight in plant mass every day.

As many as 6, Florida manatees and 6, Antillean manatees are estimated to live in the wild currently, according to the FWS.

Donations help fund manatee conservation. Historically, Antillean manatees were hunted by local natives and sold to European explorers for food. Additionally, since studies have shown that death does not appear to be a common result of capture, it is believed that capture and care is necessary for manatees inhabiting Florida, Puerto Rico, and Belize.

After a long sea voyage, sailors may have thought they were seeing sirens, or mermaids, when they were probably seeing manatees or dugongs. Manatees evolved from the same land animals as elephants over 50 million years ago and the fossil record shows a much more diverse group of sirenians than we have today, with dugongs and manatees living together throughout their range.

They do have plenty to worry about when it comes to humans though.The West Indian manatee (Trichechus manatus) or "sea cow", also known as American manatee, is the largest surviving member of the aquatic mammal order Sirenia (which also includes the dugong and the extinct Steller's sea cow).

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