What structure behind the retina grants walleye advantage in dim conditions?
Answer
Tapetum lucidum layer
The walleye possesses a unique anatomical feature behind its retina called the tapetum lucidum layer. This specialized structure is highly sensitive to light, granting the fish a significant competitive advantage, especially in low-light environments. This adaptation allows them to hunt effectively when many other species struggle to gather sufficient visual information, which is why anglers commonly observe peak activity during dawn, dusk, and throughout the night.
