Brook Lamprey Lampetra planeri (L 15cm) Elongated fish, resident in unpolluted streams and rivers. It spends most of its 3-5 year lifespan as a larva living buried in silt; here it filters organic matter. Following metamorphosis, adults are sometimes seen spawning in Apilr-May in shallow gravel beds; the sucker is used to move stones to create an egg-laying site. Adults die after spawning.
