Glycera sp.:
Glycera sp.: This genus of worms is recognized by the fact that when one presses down on the part of the body behind the head and the pharynx is everted, four tiny dark "teeth" can be seen arranged around the perimeter of the pharynx. Earthworm-like seaworm (Lumbrineris luti) has four "teeth" arranged like jaws on the same plane, and Nereis procera has two pincer-like jaws. Glycera has hemoglobin, like us, which explains the red stripe and pinkish coloration. While many worms in this group can inflict a nasty bite, this is not one of them.
