The Sirenia are fully aquatic, herbivorous mammals that inhabit rivers, estuaries and coastal marine waters. Commonly called manatees, dugongs, or seacows, they have major aquatic adaptations: forelimbs have modified into arms used for steering, the tail has modified into a paddle used for propulsion, hindlimbs (legs) are but 2 small remnant bones floating deep in the muscle. They appear fat, but are fusiform and hydrodynamic. Skulls are highly modified for taking breaths at the water's surface and dentition is greatly reduced. They have only two teats, located under their forelimbs, similar to elephants (see the picture of manatee mother/calf pair).

Manatees (Trichechidae) and dugongs (Dugongidae) are endangered species. All four living species are vulnerable to extinction from habitat loss and other negative impacts related to human population growth and coastal development. Manatees and dugongs are the only marine mammal classified as herbivores. Unlike the other marine mammals (dolphins, whales, seals, sea lions, sea otters, walruses, and polar bears) sirenians only eat seagrasses and other aquatic vegetation. Unlike other marine mammals, sirenians have an extremely low metabolism and zero tolerance for cold water. Like dolphins and whales, manatees and dugongs are totally aquatic mammals that never leave the water - not even to give birth. The combination of these factors means that sirenians are restricted to warm shallow coastal waters, estuaries, and rivers, with healthy ecosystems that support large amounts of seagrass and/or other vegetation.
