Least Brook Lamprey
Lampetra aepyptera
Adult least brook lampreys inhabit clear, small streams with gravelly areas suitable for spawning. Unlike parasitic lampreys, adults do not feed after metamorphosis and instead rely on stored energy. They use their oral disc to hold position in moving water and gather at shallow nests to reproduce. Adults die shortly after the breeding season.
