West Branch Warroad River
Roseau County, Minnesota
Spawning sea lamprey throughout the stream.
This is a Southern Brook Lamprey that was found in a creek in Georgia. This was pulled up while seining. We pulled up multiple of them. However, they are an invasive species here. The shape of the head along with the dorsal fin shows that this is an adult.

Lampreys (sometimes also called lamprey eels) are an order of jawless fish, the adult of which is characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is derived from lampetra, which translated from Latin means "stone licker" (lambere "to lick" + Greek πέτρα "stone").
