Also known as sea cows, these herbivorous hulking creatures feed mainly on sea grass, scoffing more than a tenth of their bodyweight each day. They have a flat, paddle-shaped tail and come up for air every few minutes. Their head and face are wrinkled, with whiskers on the snout. The manatee’s closest relatives are the elephant and the hyrax (a small, gopher-sized mammal). Manatees are not to be confused with their cousins, dugongs, another sea cow species found around Australia’s Great Barrier Reef, Thailand and elsewhere. Florida’s Crystal River is a known hotspot, with manatee-spotting tours and the chance to snorkel with them.
