Researchers in New Zealand have had the rare opportunity to study the world's largest eyes, those from a remarkably well-preserved specimen of a colossal squid. (Lest you think this is hyperbole in reporting: no, in fact, the colossal squid is indeed a different and larger species than the giant squid.) The eyes are the size of soccer balls—the pupils alone measure three inches across—and could very well be the largest ocular organs to have ever existed in the animal kingdom.
