“Why are some littoral beasts fur covered (i.e. beavers) and others nearly naked (elephants, rhinos, hippos)?”
The pattern seems to show that all fully aquatic mammals lose their fur (cetaceans), semi-aquatic or historically semi-aquatic mammals in tropical or subtropical zones lose their fur (hippos, elephants, rhinos, pigs), while semi-aquatic mammals in colder areas adapt their fur to make it waterproof (polar bears, beavers, voles, etc.) Seal pups that are born on land in arctic conditions are born with fur, but quickly lose this and replace it with fat by the time they enter the water. Fur is obviously an important insulator in cold environments if anytime is spent on land, so beavers could not do away with it completely.

Aquatic mammals with hair usually have little hair that does not affect much or hair of types which keep the skin dry. Hominids do not have the type of hair which can keep the skin dry.
