Sea Spider
Despite their superficial resemblance to spiders, sea spiders are not related to them. The 500 to 600 species are distributed in all seas, from shallow waters down to 12,000 feet. They are most numerous in polar seas, in both Arctic and Antarctic Oceans. The smallest sea spiders are only a fraction of a inch across. The largest, living in deep waters, are over two feet across. They probably got the name sea spider because of their appearance and also because when they latch onto their prey, they puncture their victims skin and suck out all of their body fluids, just as a spider does.
