The Churaumi Aquarium at Ocean Expo Park (the site of the 1975 World Expo) in Nago, Okinawa has a lot of local aquatic life. The main attraction are a trio of whale sharks. Japan currently has five whale sharks in captivity, while the rest of the world combined has eight. The three in Okinawa are often the focus of animal rights groups because of their status as endangered species as well as the fact that they are ocean-dwelling creatures in a small tank.
The critter posing for me in this photo is the giant Okinawan Spiny Lobster. I wanted to eat him, along with the Japanese people muttering "美味しそう。。。" ("Looks delicious...") behind me.
