[2] This species is known by the common name spear squid,[3][4] or yari-ika in Japanese.

[3] This squid is native to the western Pacific Ocean along the coast of Asia.

It spawns in spring and summer in the northern part of its range, and in winter farther south.

The consort sperm fertilize eggs internally, while sneaker sperm fertilize the eggs as they emerge from the female's body and brush past the external sperm-deposition site near the mouth.

In order to increase catches, artificial substrates have been installed along the coast of Japan to provide more egg-laying sites.
