Aquatic arthropods

Underwater World Singapore has quite unique collection of crustacean. Ranging from normal beach's yu-yu to coconut crab. Some of them are ugly, others are weird looking. Some looks fat with large shell. One of the skinny looking crab is Arrow crab (stenorhynchus seticornis). Apparently this crab is one of the famous aquarium pet. But the main attraction is the Japanese Spider crab (macrocheira kaempferi). It is the largest crab alive; fully grown it can reach a leg span of almost 4 m! And it's natural habitat is on the bottom of the Pacific Ocean (some 300 m-400 m deep) around Japan. Actually you also can find them in Meidi-ya (japanese supermarket), of course in pieces. But we did see them -alive and kicking- sold in wet market in Hongkong. Wonder how it taste ya?
