Everything is in the legs

Sea spiders can make any arachnophobe sweat. With their long, spaghetti-like legs, they do not look like any other marine animal. The body is almost nonexistent, and most organs are located in the upper joints of the legs. In spite of the name, they have nothing to do with spiders apart from sucking life out of their prey. Sea spiders feed on small, defenceless prey, as larger animals would easily be able to break their thin legs.
