eyeshine

They can almost completely camouflage their eyeballs, using a glittery “eyeshine” that they tune to blend in with different shades of blue-green ocean water.

So the larvae shrimp and larvae prawns and many other larval crustaceans just covered the dark eye pigments with crystals that make their eyeshine color the same as the water color in their native habitat.

This eyeshine adaptation was first discovered in mantis shrimp larvae in 2014.

The best part, he said: “If you have a headlamp on, you’ll see their eyeshine.”

You likely have caught larger glimpses of deer or raccoon eyeshine in the headlights, the work of specialized tissue called tapetum.
