It looks like it leapt straight out of Picasso’s canvas, but the Cock-Eyed Squid has a good reason for its unusually mismatched eyes. However, being dwellers of the ocean’s Twilight Zone,  200-1,000 metres deep where sunlight is scarce, understanding that reason hasn’t been easy.

They were first described in the 1800s, but it took around 150 years for scientists to crack the curious case of the Cock-Eyed Squid. Finally, in 2017, researchers found that Histioteuthis uses its larger eye to see ambient sunlight while its smaller, right eye points downward to detect bioluminescence from prey animals.

Eyes aside, the Cock-Eyed Squid is sometimes nicknamed Strawberry due to its bright pink body and seed-shaped photophores. These photophores can match with light from above, allowing the squid to become nearly invisible.
