Sea lamprey migration in the Sheepscot River, Maine

NRCM's Allison Wells and her young son happened upon the sea lamprey migration in the Sheepscot River, Coopers Mills, Maine, and captured this video. The sea lamprey is a native, parasitic fish that has a strange, disc-like mouth that it uses for feeding on the flesh of other fish. It also uses it to grasp onto rocks as it migrates up rivers from the ocean to spawn.
