Histioteuthis
Histioteuthis is a genus of squid and the only member of the Histioteuthidae family. It goes by the common name cock-eyed squid, because in all species the right eye is normal-sized, round, blue and sunken; whereas the left eye is at least twice the diameter of the right eye, tubular, yellow-green, faces upward, and bulges out of the head.
