What are characteristics of a Humboldt squid attack?

Some scientists believe that Humboldt squids are more likely to attack divers who utilize reflective equipment or flashing lights, indicating an attraction of the squid toward this kind of phenomenon. Other scientists say that the Humboldt squid only attacks divers when it is in a feeding frenzy.

Humboldt squid live in the eastern Pacific Ocean and form large groups containing as many as 1,200 individuals. Although this squid is relatively short-lived, it can rapidly reach a length of 6 feet excluding its arms and may weigh up to 100 pounds. The diet of the Humboldt squid includes fish, crustaceans and other cephalopods. It is also cannibalistic and known to attack injured members of its group.
