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
Cephalopod limb infundibulum and acetabulum causes attachment and detachment. Many octopus arm anomalies have been recorded, including a 6-armed octopus (nicknamed Henry the Hexapus), a 7-armed octopus, a 10-armed "Octopus briareus", one with a forked arm tip, octopuses with double or bilateral hectocotylization, and specimens with up to 96 arm branches. Branched arms and other limb abnormalities have also been recorded in cuttlefish, squid, and bobtail squid. Cephalopod limbs and the suckers they bear are shaped in many distinctive ways, and vary considerably between species. Some examples are shown below. For hectocotylized arms see hectocotylus variability. Cephalopod limb All cephalopods possess flexible
