Daily fish fact #395
Walleye!
It is named after its rather opaque eyes, which are adapted to seeing in the dark well; their eyes are equipped with an extremely reflective layer, the tapetum lucidum, which can also be found in the eyes of felines! Walleyes are nocturnal predators, choosing to hide among logs or aquatic plants during the day.

Walleye!
Also called yellow walleye, yellow pike or pickerel! They're named for their very opaque-looking eyes, caused by the reflective tapetum lucidum; a layer of tissue found in the eyes of many nocturnal animals that enhances night vision, the shine in a cat's eye is due to the tapetum lucidum, for example. Thanks to this enhanced night vision they can thrive in waters with low visibility, giving them an edge over other fish that hunt with sight!
