I made a post about what to do when you're not surfing about the Long Beach Aquarium, but I had some extra photos. At the Long Beach Aquarium, there are a huge host of creatures (yes, even some birds). When I visited, I took photos of some of the most exotic species including the Saw Tooth Shark. See the photos below (you'll recognize which is the Saw Tooth). You don't want to run into one of these in the water.
We were also able to feed and hold tropical birds that live around the water where these exotic species of marine mammals are found. When you're out surfing, try not to think too hard about what's lurking underneath.
