giant sea spider

Some exotic creatures lurk in the polar seas, but perhaps none is more bizarre than the giant sea spider. There are hundreds of sea spiders in oceans around the world, but the giant sea spider weighs about 1,000 times more than its relatives. Its legs can span up to two feet across, but its body usually measures just a couple inches long.
