Glass Squids

Squids in the family Cranchiidae are referred to as glass squid because of the transparent nature of most species. They are characterized by a swollen body and short arms. They are also sometimes referred to as cockatoo squid because several deep-sea species have been observed exhibiting a peculiar posture (cockatoo posture) with the arms and tentacles folded back over the head.
