text: Vampire squids are well-adapted to live in deep sea environments with photophores, large circular organs found on the posterior (rear) end of each fin and distributed on their mantle, a funnel, head, and aboral surface (the surface opposite the mouth (or oral surface)), that produce luminescent clouds of glowing particles that last between 2-9 minutes (Grzimek 1972, Wood and Ellis 1999, Wood 1999).
