The Giant Squid (Genus Architeuthis) is a deep-ocean creature that can grow to 13m. The giant squid uses the two tentacles to catch prey which includes deep-sea fish and other squids, they then feed with the beak. The only known predator of the giant squid is the sperm whale (and possibly the pilot whale) and the smaller ones are preyed on by sharks. These creatures are very widespread but are rare to find in tropical and polar latitude.
an aggregation of sperm whales in the waters near sri lanka. photos by tony wu, who described the scene thusly: “there were hundreds, perhaps thousands, gathered in all directions as far as the eye could see. most were adult females, though there were some large males present, as well as juveniles. the whales fed intermittently, but also spent substantial time at the surface and in shallow water socializing.”
