Considering this, do squid have one eye or two?
The colossal squid's eyes are placed so they face forward, giving the squid binocular, or stereoscopic, vision. The giant squid, in contrast, has eyes placed on each side of the head. It can see forwards and behind to detect predators, but does not have the binocular vision needed to judge distances.
What color are an octopus's eyes?
Octopuses, squid and other cephalopods are colorblind – their eyes see only black and white – but their weirdly shaped pupils may allow them to detect color and mimic the colors of their background, according to a father/son team of researchers from the University of California, Berkeley, and Harvard University.
What is the function of a squid's eye?
