You HAVE to read this article about a diver/photographer named Scott Cassell, who goes looking for giant squid. It's amazing. An excerpt:
For most people, the word “squid” probably conjures images of deep-fried appetizers, not flesh-eating carnivores. But the truth is, Humboldt squid have approximately 1,200 sucker discs, each one lined with 20 to 26 needle-sharp teeth. This allows the Humboldt to attack its prey with more than 24,000 teeth at once. And nestled in its bed of eight muscular arms and two feeding tentacles is a disproportionately large, knife-edged beak similar to a parrot’s. But the Humboldt is much larger than a parrot: they have been found as large as 14 feet in length and weighing more than 700 pounds.
In addition to the Humboldt’s enormity and impressive array of weapons, this magnificent mollusk possesses a legendary ferocity. The local Mexican fishermen call it Rojo Diablo, or Red Demon. When I arrived in Mexico for the dive, several fishermen told tales of how people had experienced violent deaths after falling in the water with these red demons: “…they would be pulled down and devoured in moments.”
