a single nostril is located between the eyes. Larvae are a brown to tan all over have no eyes (instead they have eyespots) and are called ammocoetes. They also have seven gill openings and do not have any paired fins, they have only a long continuous fin runs from the dorsal to the ventral side. Ammocoetes also have no teeth and instead have an oral hood which houses skin extensions that help them filter particles out of the water as they draw it into their oral cavity.

Silver lampreys use their oral discs to attach to their hosts, then cut through the skin and scales with their teeth. The lamprey will remain attached to the host over a long period of time, but they seldom kill their host (which have coevolved with these lampreys). Adults feed on a variety of fishes, including

Silver lampreys possess a cartilaginous skeleton, and adults generally grow to a length of 12 inches and are silvery or bluish in color when spawning. Prior to spawning adults are often a dull brown or tan color. The

Adult silver lampreys prefer the clear waters of large streams, rivers, and lakes. Adults migrate to nest in flowing water that has stoney or gravelly bottom material. When they hatch, the larvae move to slowly flowing areas initially with thick organic layers. As they grow in size, they begin to
