#62 || Dr. Trevor Keyler: The Hidden World Through a Walleye’s Eyes
Tuesday, 1 September, 2026
Dr. Trevor Keyler has spent years investigating what the underwater world looks like through the eyes of a walleye. His research reveals a fish with an astonishingly sophisticated visual system — one perfectly adapted to hunting in the low-light world beneath the surface.Trevor explains how walleye eyes capture incredibly faint light, why they're most sensitive to the blue-green wavelength and how water clarity dramatically changes the underwater light environment. And then there's this jaw-dropping finding: under ideal conditions, a walleye can detect light at depths approaching 77 metres .... or 250 feet.But there's much more to the story than simply, "How deep can a walleye see? " Trevor explains the crucial difference between detecting light and seeing prey well enough to capture it — and his findings offer fascinating insights into lure colour, contrast, silhouette, water colour, twilight, moonlight and why walleyes come alive as the sun is disappearing.Send us a message
