Reply to comment by LornAltElthMer in A cougar was observed swimming 1.1 km (0.68 miles) to an uninhabited island in Pugent Sound. Researchers find other records implying mountain lions can swim even farther to hop between islands, likely >2 km. “We are redefining the mountain lion in our minds as an animal that can swim.” by TR_54

Oh damn, true, I forgot that, as they're pretty aquatic, but yeah, you are right, they just run underwater, haha.

Eh, they're just the part of the branch that stayed in the shallows. (Whale evolution docs are cool)

Seems like going back from land to water has happened quite a few times. Taxonomy is interesting and your comment made me look a bit, and to my surprise, hippos are more closely related to cetaceans than they are to manatees. I mean, I had never given it any thought before, but I didn't realise how different manatees and dugongs are from cetaceans.

Also, seals and walruses. Weird that a hippo can't swim, but walruses can. They both look heavy enough, but guess hippos do be a bit denser.

I'm guessing with the walruses it's the flippers that make the difference.

Just going by appearance I'd have guessed a hippo and a manatee would be more closely related, but here we are ;-)
