The eyes are one of the prominent characteristics of the octopus but also of cephalopods in general. Already from outside, the eyes appear to be special.

Do octopuses have eyesight like humans?

Although the camera eye of the octopus is very similar to that of humans, phylogenetic and embryological analyses have suggested that their camera eyes have been acquired independently. It has been known as a typical example of convergent evolution.

How many eyes does the octopus have?

Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim.
