Q: Are walleyes more sensitive to light than other fish? -Dale Mitchell, Eagle, Wis.
A: Absolutely. This helps explain much walleye behavior, such as their tendency to hang deep during the day and feed over shallow reefs or flats after dark. The eyes of a walleye (and a sauger) have an unusual reflective membrane in the retina that enhances their light-gathering power, much like those of a deer or other nocturnal animal.
