Killers whales. They eat practically everything (cetaceans, sirenians, pinnipeds, sea otters, sea turtles, sharks, rays, bony fishes, squid).
The dugong is a marine mammal belonging to the group known as Sirenians. It is the manatee's closest relative.
They are called sirenians. Named after sirens also known as mermaids.
Most probably the manatee or dugong, sea mammals known as sirenians. The female nurses her young from teats that are placed high on the torso, as are human breasts.

The non avian dinosaurs became extinct 65.5 million years ago. The earliest sirenians, (the order that includes manatees), didn't evolve until about 50 million years ago, 15 million years after the extinction of the non avian dinosaurs. However, scientists consider birds a group of dinosaurs, and, because birds still exist today, manatees do coexist with avian dinosaurs.
All mammals have some hair, but cetaceans, sirenians, elephants, domestic pigs, naked mole rats, hippopotamuses, rhinoceroses, walruses, sea lions, some seals, and others lack dense, inslulating body hair. Humans' body hair is not very dense either. Thus, hair is a characteristic of mammals, but dense hair covering the entire body is not.
