Humboldt squid squid uses its barbed tentacle suckers to grab its prey and slices and tears the victim's flesh with its beak and radula. They often approach prey quickly with all 10 appendages extended forward in a cone-like shape.

These two longer tentacles can reach full length, grab prey, and retract so fast that almost the entire event happens in one
Neon flying squid fourth arm. Another distinguishing characteristic of "O. bartramii" is the presence of 4 to 7 toothed suckers on the tentacular club, near the nearest carpal suckers of the carpal locking apparatus. This is especially useful in differentiating it from the orangeback flying squid ("Sthenoteuthis pteropus"). Photophores are present but are small, irregular, and restricted to the ventral side of the mantle, head, and tentacles. Visceral photophores are absent. Like other ommastrephids and onychoteuthids known as 'flying squid', neon flying squid are so named for their ability to shoot out of the water, much like flying fishes. They sometimes unintentionally land
