Classification/Description
The scientific
name for Walleye has changed recently from
Stizostedion vitreum to Sander vitreus. The name
has changed due to the fact that the species
Zander's (Stizostedion
lucioperca) genus is so closely related to that of
the walleye that they are practically considered the
same fish now. Since the Zander was documented first, they had to change
the genus for walleye. The genus Sander remained and
that is how the name changed.

Walleye can range in color from dark olive to a yellow/gold
appearance that fades to white on the belly. Their body
is very streamline and cylindrical. They are named for
their large glossy eyes. The reason for their larger
eyes is the tapetum lucidum, a reflective layer of
pigment, that helps them see their prey even in poor conditions. Another defining aspect of walleye is
they have dark bars that run horizontal down the back
and have dark blotches on their sides. Walleye also have
a mouthful of very prominent teeth that are used to
capture their prey. Learn what
