Sperm storage and mating in the deep-sea squid Joubin, 1931 (Oegopsida: Octopoteuthidae).

Spermatangium implantation is reported in the large oceanic squid , based on ten mated females from the stomachs of sperm whales. Implanted spermatangia were located in the mantle, head and neck (on both sides) or above the nuchal cartilage, under the neck collar and were often associated with incisions. These cuts ranged from 30 to 65 mm in length and were probably made by males, using the beak or arm hooks.
