Pycnogonids by Cliff Pickover

Pycnogonids, or "sea spiders," are among the strangest creatures on Earth. Giant pycnogonids are featured in the science-fiction novel Spider Legs, cowritten with Piers Anthony. In the novel, giant sea spiders terrorize people on the Newfoundland shores.

About 600 species are known. They are mostly small forms not over 10mm long, although some of the deep-sea forms may reach several feet in length.

Pycnogonids are carnivorous animals that suck out the juices of their prey. The sea spider's digestive system extends into the legs. Sea spiders are more common in the cold Arctic and Antarctic seas than they are elsewhere, although they are found in all seas.
