Octopoteuthis deletron is a species of
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).
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.[3]
The male O. deletron has a penis, which is unusual among squids. Males find it difficult to detect the sex of other individuals they encounter in the dark depths, so they have adopted a strategy of attaching sperm packets to all individuals they meet.[4]
O. deletron are the most common species found in the stomachs of
giant grenadier.[6] It is also eaten by the enigmatic Perrin's beaked whale (Mesoplodon perrini).[3]
