什么動(dòng)物的眼睛最大？
[ 2007-01-15 10:14 ]
要說世界上最大的眼睛，得數(shù)大王烏賊的眼睛了。大王烏賊是一種生活在深海中的巨型烏賊，它眼睛的直徑可達(dá)21厘米，有排球般大小。
 The eyes of the giant squid (Architeuthis dux) can
be up to 25 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.
