The cock-eyed squid has one large, yellow, protruding left eye and one smaller, blue, embedded right eye. Scientists think the squid uses the large eye to see sunlight and the smaller one to see bioluminescence.
This squid is found in the deep sea to depths of about 3,000 feet, and is prey for deep-diving elephant seals. It is also covered in tiny photophoresorgans that produce lightwhich can flash in complex patterns, presumably to communicate with other squid and warn off predators.
