The squidworm is measured to be nearly four inches long, quite sizable for a marine worm. It is named for its head that looks like it's covered in squid-like tentacles. This worm has an abundance of various appendages, some of which are even longer than its body. Eight arms are used for breathing, and two long, coiled appendages are used for feeding. Six pairs of sensory organs emerge from its head to provide the squidworm with the ability to taste and smell, and propulsion paddles are present down the length of its body to allow for upright swimming.
