Abstract:The squid Histioteuthis dofleini, like other members of the family
Histioteuthidae, has a large left eye and a small right eye. The large eye points in a
dorsal posterior direction while the squid typically orients at an oblique angle with
the arms downward. The large eye, as a result, points vertically upward. The small
eye appears to be directed ventrolaterally. This squid occurs primarily at depths of
500 to 700 m during the day where it is exposed to low levels of downwelling light.
Presumably the large eye utilizes this faint downwelling light while the smaller eye
utilizes bioluminescent light.
