Seals are cute. Sea lions are fucking mean bastards and will fuck you up if you mess with them. I was snorkeling in Monterey Bay one time when this seal lion swam up about 6" from my face, opened his mouth full of nasty teeth, and made this crazy sea lion growling noise. I started swimming away and he stayed right with me until I got out of his territory. I've had them bump me when sea kayaking too. It still sucks that 3 of them died though.
