Today I read an article about how manatees are smarter than we think. Apparently when the manatee bumps a ball with his nose he gets a snack. My betta could do that (well probably not now).
I don't mean to be an asshole, but aren't dolphins like 3 million times smarter than that? And really while we're at it; I don't think any animal is truly intelligent until they can invent things that can destroy their entire species.
