"The Humboldt squid is a large, predatory squid found in the waters of the Humboldt Current in the Eastern Pacific Ocean. These squid hunt in packs of up to 1,200 and use their ability to rapidly change color to communicate with each other. Scientists believe that they are highly intelligent and use complex communication. Each tentacle is covered with suckers filled with razor sharp teeth which they use to drag their prey to their beaks. They often approach prey quickly with all ten appendages extended forward in a cone-like shape. Upon reaching striking distance, they will 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 dramatic lacerations to human flesh. The whole process takes place in seconds. To make matters worse, these creatures love hunting humans – they do it very frequently and most fisherman in the area know of at least one or two friends who have been eaten by a pack of these monsters."
