Family: Petromyzontidae (lamprey)
Profile - University of Michigan, Museum of Zoology
5 species of lamprey inhabit the Great Lakes watershed. These lamprey
species may be distinguished by the form of the dorsal fin(s), number
of body segments, and teeth. Larval (young) lamprey are generally distinguished
by their pigment patterns (color). Although both the native chestnut
and silver lampreys are parasitic on fish as adults, only the invasive
sea lamprey has serious impacts on fish populations.
