Night Vision

At almost 10 inches in diameter, these are the largest eyes ever recorded. The huge pupils take in 144 times as much light as a human’s. “Vision is obviously an important sense, since so much investment has been made in the eyes and the optic lobes,” says Eric Warrant, an invertebrate-vision specialist at the University of Lund in Sweden.

Killer Tentacles

One common hunting strategy among smaller squid (it’s thought that all squid exhibit similar behavior) is to strike prey first with their tentacles. The 10-foot-long tentacles of the colossal squid have hooks that swivel, grabbing hold of prey. When this squid was caught, it was eating a 6.5-foot-long Patagonian toothfish.

Clues to Their Size

From beak remnants, researchers have determined that colossal squid account for 77 percent of the sperm whale’s Antarctic diet. “The biggest beaks recorded are still larger than the ones we’ve had in our specimens, so we know the animal must get bigger still,” Bolstad says.
