Histioteuthis heteropsis

Histioteuthis heteropsis, also known as the Strawberry Squid, is a species of cock-eyed squid. The scientific nomenclature of these squid stems from 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 see objects against dim light, while the smaller eye is more able to view bioluminescent light sources.[1]
