River and sea lamprey

Lamprey are a member of the jawless fishes Petromyzonidae.   Lamprey are one of the most primitive of all living vertebrate animals having a distinct mouth with no lower jaw, instead it is surrounded by a round sucker-like disc within which the adults have strong, rasping teeth.

The river and sea lamprey are anadromous species which spawns in freshwater but complete part of their lifestyle in estuaries or at sea.  Estuaries are considered important migratory routes with near-shore coastal margins being important migratory and feeding grounds
