Largest eye
Last updated: October 11, 2017 at 2:24 am
Scientists have extrapolated that the colossal squid (Mesonychoteuthis hamiltoni) has the largest eyeballs of any living creature today at up to 30.5 cm (12 in.) in diameter. It is reported that the eyes of a giant squid washed up in Newfoundland, Canada, measured 40 cm (15.75 in.).
