Giant Squid - world's larget eyes

"A giant squid’s eyes have a diameter of 15 inches which are the largest of any animal."
Kingdom: Animalia
Phylum: Mollusca
Class: Cephalopoda
Subclass: Coleoidea
Order: Teuthida
Suborder: Oegopsina
Family: Architeuthidae
Genus: Architeuthis

Giant squid have a sophisticated nervous system and complex brain, attracting great interest from scientists. They also have the largest eyes of any living creature except perhaps colossal squid — over 30 centimeters (1 ft) in diameter. Large eyes can better detect light (including bioluminescent light), which is scarce in deep water. Architeuthis) is a deep-ocean dwelling squid in the family Architeuthidae, represented by as many as eight species. Aristotle, who lived in the fourth century B.C., already described a large squid, which he called teuthus, distinguishing it from the smaller squid, the teuthis. He mentions that "of the calamaries the so-called teuthus is much bigger than the teuthis; for teuthi [plural of teuthus] have been found as much as five ells long."

- The larger one has eyes around 27 cm across, believed to be world's biggest
- It weighs almost half a tonne and measures about 32 feet (10 meters) in length
- Scientists believe that there may be even larger colossal squids in existence


Article from Wikipedia about Giant Squid:
The giant squid (genus: Architeuthis) is a deep-ocean dwelling squid in the family Architeuthidae, represented by as many as eight species. Giant squid can grow to a tremendous size: recent estimates put the maximum size at 13 metres (43 ft) for females and 10 metres (33 ft) for males from caudal fin to the tip of the two long tentacles (second only to the colossal squid at an estimated 14 metres (46 ft), one of the largest living organisms). The mantle is about 2 metres (7 ft) long (more for females, less for males), and the length of the squid excluding its tentacles is about 5 metres (16 ft). There have been claims reported of specimens of up to 20 metres (66 ft), but no animals of such size have been scientifically documented.
