They belong to the pelagic squids of order Oegopsida. Found at depths of {{convert|400|to|800|m|abbr=on}} in the Pacific Ocean, they have been known to grow to {{convert|24|cm|abbr=on}}. 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 northern elephant seals sampled off the coast of California.[5] It is an important prey item of the giant grenadier.[6] It is also eaten by the enigmatic Perrin's beaked whale (Mesoplodon perrini).[3]References1. ^{{cite journal | author1 = Barratt, I. | author2 = Allcock, L. | last-author-amp = yes | year = 2014 | title = Octopoteuthis deletron | journal = The IUCN Red List of Threatened Species | volume = 2014 | page = e.T163334A999352 | doi = 10.2305/IUCN.UK.2014-1.RLTS.T163334A999352.en}} Downloaded on 10 March 2018. 2. ^{{cite web | url = http://www.marinespecies.org/aphia.php?p=taxdetails&id=342057 | title = Octopoteuthis deletron Young, 1972 | accessdate = 10 March 2018 | publisher = Flanders Marine Institute | year = 2016 | author = Julian Finn | work = World Register of Marine Species}} 3. ^1 {{cite web |url=http://blogs.smithsonianmag.com/science/2012/08/video-this-deep-sea-squid-breaks-off-its-own-arms-to-confuse-predators/ |title=This Deep-Sea Squid Breaks Off Its Own Arms to Confuse Predators |publisher=Smithsonian.com |last=Stromberg |first=Michael |at=With video |accessdate=August 4, 2012}} 4. ^{{Citation | last=Gorman| first=James | title=Amorous Squid Seeks Partner: Any Sex Will Do | newspaper=The New York Times | publication-place=New York | date=21 September 2011 | page=A1 | url=https://www.nytimes.com/2011/09/21/science/21squid.html?nl=todaysheadlines&emc=tha23 }} 5. ^{{cite book |title=Elephant Seals: Population ecology, behavior, and physiology |last=Le Beouf |first=Burney J. |authorlink= |author2=Richard M.
