I love pinnipeds. They make me laugh.
We came across hundreds of California sea lions (Zalophus californianus) out in open ocean the other day...barking, frolicking, and being generally ridiculous.

There are a lot of sea lion colonies around, but from what I gather, it's rather unusual to see so many individuals together in open water, so it was quite a treat to be among them (though they certainly smelled bad at times!).
Perhaps the most amusing sight was watching them catch some R&R, thermal regulating by sticking their flippers up in the air while dunking the rest of their bodies in the water.
Here's a pair of the posing pinnipeds, which for all practical purposes looked to me like a sculpture you might find at a museum of modern art:

In this instance, it was a husky male and adorable female. On a thermal-regulating date perhaps?
