Here, we show clearly that cuttlefish must be color blind, as they showed non-disruptive coloration on the checkerboards whose color intensities were matched to the Sepia visual system, suggesting that the substrates appeared to their eyes as uniform backgrounds. it just has one type of cone cell. But cephalopods a group that includes octopuses, squid, and cuttlefish have only 1 type of light receptor in their eyes, which has led scientists to believe that they are incapable of color vision.

Cuttlefish have big, dark red eyes with a distinctive w-shaped pupil; these eyes are extremely well-developed and have no blind spot because the cuttlefish's optic nerve is behind the retina. Cuttlefish are colorblind, but they can see contrasts in light caused by polarization. Most cuttlefish are expected to have a 2 year life span and female cuttlefish will die shortly after laying eggs. mboydp June 17, 2017 at 3:31 pm.
