Giant squid, any member of a genus of large, elusive cephalopods inhabiting deep regions of temperate to subtropical marine waters. Thought to be the largest or second largest living invertebrate, the giant squid has been frequently depicted as a sea mon
Background The eyes of giant and colossal squid are among the largest eyes in the history of life. It was recently proposed that sperm whale predation is the main driver of eye size evolution in giant squid, on the basis of an optical model that suggested optimal performance in detecting ...
The eye diameter of the giant squid, which measures up to 27 cm (10.6 inches), is among the largest of all living animals; it is second only to that of the colossal squid. Such large eyes are thought to have given the giant squid and the colossal squid the ability to discern large ...
Eye of the giant squid has 10 inches in diameter. It is the size of the beach ball. Giant squids move like all other Cephalopods by rapidly expelling the water from their mantle. Due to their size, they can expel a lot of water, which make them one of the fastest squids in the ...
this extreme absolute eye size, we developed a theory for visual performance in aquatic habitats, leading to the conclusion that the huge eyes of giant and colossal squid are uniquely suited for detection of sperm whales, which are important squid-predators in the depths where these squid live....
The eyes of giant and colossal squid are among the largest eyes in the history of life. It was recently proposed that sperm whale predation is the main driver of eye size evolution in giant squid, on the basis of an optical model that suggested optimal performance in detecting large luminous...
"The reason we succeeded where others have failed is because we paid attention to the visual system of the squid. It has the largest eye of any animal on Earth, it's a visual predator," she says. "Before, I went down in submersibles and shined a light only to wonder how many animals...

A recent, lucky opportunity to study part of a giant squid brain up close in Taiwan suggests that, compared with cephalopods that live in shallow waters, giant squids have a small optic lobe relative to their eye size. Furthermore, the region in their optic lobes that integrates visual infor...
* Since Giant Squids live on the depth of 3,000 to 6,000 feet, they have huge eyes which enable them to detect objects in the light-less ambient. The eye of the Giant Squid is on the average 10 inches in diameter, about the size of the beach ball. * Giant Squids move like all...
