Doryteuthis opalescens is a cannibalistic predator that feeds on smaller prey species such as fish, crabs, shrimp, mollusks, and other juvenile squids. [3] It uses its two longer tentacles with tentacular clubs on the end to snare and catch its prey.
This provides the squids some advantages for jet propulsion swimming. The stiffness means that there is no necessary muscle flexing to keep the mantle the same size. In addition, tunics take up only 1% of the squid mantle's wall thickness, whereas the longitudinal muscle fibers take up to 20% of the mantle wall thickness in octopuses. [81]
Studies have shown that juveniles feed on euphausiids and arrow worms, while older individuals feed mostly on small crabs, but also on polychaetes and shrimp. Adults feed on fish (clupeids, myctophids) and squid larvae/juveniles, and those larger than 16 cm feed on fish and squid.

It is a squid in the family Gonatidae, found most commonly in the northern Pacific Ocean from Japan to California. They are one of the most abundant cephalopods off the coast of California, mostly found at deeper depths, rising during the day most likely to feed. The mantle size of G. onyx has been known to reach up to 18 cm (7.1 in).
A Humboldt squid that washed up on a Santa Barbara shoreline. The Humboldt squid lives at depths of 200 to 700 m (660 to 2,300 ft) in the eastern Pacific (Notably in Chile and Peru), ranging from Tierra del Fuego north to California. Recently, the squid have been appearing farther north, as far as British Columbia. [11]
