Manatees, Dugongs, and Sea Cows

Manatees and dugongs (of the order Sirenia) are large mammals that live in tropical and subtropical waters. Due to their size, demeanor, and the fact that they graze on seagrass, they’re known as sea cows, but they’re more closely related to elephants.

A recently extinct dugong, the Steller’s sea cow, was the largest modern sirenian, measuring more than 20 feet and weighing more than 20,000 pounds.
