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. Upon reaching striking distance, they open their eight swimming and grasping arms, and extend two long tentacles covered in sharp 'teeth', grabbing their prey and pulling it back towards a parrot-like beak, which can easily cause serious lacerations to human flesh. These two longer tentacles can reach full length, grab prey, and retract so fast that almost the entire event happens in one
Little flying squid slightly less than half of the mantle length. The largest arm suckers have 9-11 sharp different sized teeth on distal two thirds of their rings. The height of the protective membrane on the arms is uniform and it is not higher than that of the suckers. The manus of the tentacles has 6-8 sucker rows in four series and the rings of the medial suckers on the manus have 16-18 moderately large, subconical teeth which alternate with low plates and are around 2.5 times largers than the marginal suckers in diameter. On the tentacles the protective membranes extends to the
