Cock-eyed Squids [Histioteuthis]

Description

Histioteuthis is a genus of squids known for the notable size difference between their left and right eyes, a feature that aids in their adaptation to deep-sea environments. These squids have a unique bioluminescent capability, which they use for counter-illumination against the faint light from above, making them less visible to predators from below. The genus encompasses a variety of species, each adapted to specific depths of the ocean's twilight zone. Their diet mainly consists of small fish and other cephalopods. Members of this genus exhibit a wide range of body sizes and colorations, reflecting their diverse habitats within the ocean's mesopelagic to bathypelagic zones.
