Jellyfish are such alien creatures. These pictures are somewhat cheating -- they're from the jellyfish tanks in the Monterey Bay Aquarium.
We ordered the underwater housing for the Canon XSi today. Hopefully, we'll get some good pictures with the fish looking straight towards us (instead of their tails). In Belize, I had to focus on fish that were less jumpy: angelfish, butterfly fish and squirrel fish.
