要说世界上的眼睛，得数大王乌贼的眼睛了。大王乌贼是一种生活在深海中的巨型乌贼，它眼睛的直径可达35厘米，有排球般大小。

 

The eyes of the giant squid (Architeuthis dux) can be up to 35 centimeters (ten inches) across, about the size of a volleyball.

 

Those large, sensitive eyes are useful in the dark waters where the giant squid lives, 200-700 meters (660-2,300 feet) below the surface of the ocean.

 

How big does it get?

 

Up to 18 m (59 ft) 

Up to 900 kg (1,980 lb, nearly 1 ton)

 

Giant squids are among the world's most mysterious megafauna (large animals). They live in deep oceans all around the world, along with at least ten other species of very large squid.

 

Like other cephalopods such as octopi, giant squids have complex, well-developed brains. They are ferocious predators, but they are also pursued and eaten by large cetaceans such as sperm whales, some of which show the obvious scars of giant squid sucker disks.
