The giant squid, in contrast, has eyes placed on each side of the head. To explain the squids' eye size, Johnsen and his collaborators first measured giant and colossal squid eyes using photos and captured animals. They obtained photographs of the eye of a freshly caught giant squid and were able examine the corpse of a colossal squid, an even larger species, from New Zealand. Their eyes are the size of basketballs. How-ever, even though the eyes of these squid may be much larger than the eyes of similarly-sized fish as indicated by the comparison of giant squid to swordfish, they may not be out of proportion compared to other squid [2]. Why do giant squid need such large eyes?" With its enormous eyes, a giant squid could see the huge glowing mass headed its way, and use its jet propulsion to make a quick escape. To find out, Johnsen and her colleagues first had to confirm the eye size of these elusive creatures, because most eye size reports were based on anecdotes. Giant squid's giant eye. The giant squid is among the largest invertebrates on Earth—with lengths measuring nearly 60 feet. For comparison, the largest fish eye is the 9-centimetre orb of the swordfish. The largest measured giant squid eye is 27 centimeters (10.63 inches), roughly the size of a large dinner plate. Background: We recently reported (Curr Biol 22:683-688, 2012) that the eyes of giant and colossal squid can grow to three times the diameter of the eyes of any other animal, including large fishes and whales. THE GIST - The pupils in squid's dinner-plate-sized eyes are 3.5 inches (9 cm) across. It is the only recognized member of the genus Mesonychoteuthis and is known from only a small number of specimens. Giant squids have eyes as big as basketballs – measuring two or three times that of any other animal. The giant squid can be seen lurching from the darkness and attacking the probe. Giant Squid Facts Description. In a search for more reliable data on the eye size of the largest deep-sea squid, we were fortunate to obtain a photograph of a freshly caught giant squid (Architeuthis sp. However, the giant squid can probably only see black and white. They are very large in size with the females being approximately 10 feet longer than the males. The Colossal squid (Mesonychoteuthis hamiltoni) is part of the family Cranchiidae. Giant squid can grow up to 43 feet long, and their terrifying size is thought to have inspired belief in the existence of the kraken, a mythological sea monster.

Whereas all giant squids don't have goliath fine china size eyeballs, most are between 5-15 centimeters (~2-6 inches), their peepers are huge.

In 2007, a stunned fishing boat crew in Antarctica filmed as their lines hauled in something that they had never seen before – a living colossal squid. found that the eye size of adult giant squid is on or above the linear regression line on a log-log plot representing the scaling relationship for 87 smaller squid species. It is almost size of the beach ball. These massive organs allow giant squid to detect objects in the lightless depths where most other animals would see nothing. Because the exponent of the power law is below 1, allometry does indeed reveal a general tendency for larger squid to have relatively smaller eyes, as predicted by our law of diminishing returns. A GIANT squid has been caught on camera in US waters for the first time ever by researchers who were looking for creatures living in the "midnight zone" of the sea.
