Glass Squid Teuthowenia pellucida
Like many mollusks, juvenile glass squid live in the plankton, then descend to deeper, darker levels as they mature. The presence of light organs, called photophores, in the tips of their arms and in the eye may help in locating a mate. Sexually mature female glass squid are also thought to produce a chemical attractant, or pheromone.
