Least Brook Lamprey

Lampetra aepyptera

Classification

The least brook lamprey (Lampetra aepyptera) is a common, non-parasitic lamprey distributed in the Mississippi River watershed, and a limited range along the Atlantic coast. Description As with all lamprey species, the least brook lamprey spends the majority of its life as a worm-like ammocoete. The ammocoete (5 mm–20 cm) is clear with a pigmented head when small (<5 cm), but becomes a dark/golden brown as it matures.
