Octopoteuthis deletron is a species of squid in the genus Octopoteuthis of the family Octopoteuthidae. They belong to the pelagic squids of order Oegopsida. Found at depths of 400 to 800 m (1,300 to 2,600 ft) in the Pacific Ocean, they have been known to grow to 24 cm (9.4 in).

Trophic ecology

This species is described as an inactive predator, having a lower metabolism and relying on ambush,[3][4] though members of this genus are higher in trophic level than glass squids and active hunters like Todaropsis eblanae.[5]

O. deletron has been found to break off its arms as a defense strategy. The squid digs hooks in one of its arms into a predator and jets away, leaving the arm in the predator's skin.[6]

O. deletron are the most common species found in the stomachs of northern elephant seals sampled off the coast of California.[7] It is an important prey item of the giant grenadier.[8] It is also eaten by the enigmatic Perrin's beaked whale (Mesoplodon perrini).[6]
