Calliteuthis heteropsis (Berry, 1913 )

Histioteuthis heteropsis, the Cock-eyed Squid, also known as the Strawberry Squid, is a species of cock-eyed squid. These squid are named for their peculiar set of differently sized eyes, one being small and blue and the other being large and yellowish. It is thought that the large eye is used to spy for food and predators in the down-welling light above the squid, while the smaller eye peers into the darkness below, seeking out bio-luminescent signals.[1]

They are slow and not easily scared, even by submersibles.[2] H. heteropsis was exhibited publicly for the first time at the Monterey Bay Aquarium on June 27, 2014[1]
