The eye of the beast was measured at about 11 in (28 cm), larger than a dinner plate and by far the largest animal eye on Earth. Blue whales, the largest living animals (up to 33 m (110 ft) long and 180 tonnes heavy), have eyes the size of those of a cow. The eye lens of the colossal squid is as big as an orange and it was found intact in one of the eyes. This is the only intact eye [of a colossal squid] that's ever been found. It's spectacular. It's the largest known eye in the animal kingdom, co-researcher Kat Bolstad, a squid specialist at the Auckland University of Technology told the Associated Press. This is the largest eye ever recorded in history and studied.
