What is a "lamprey"?

A lamprey is a primitive and jawless fish known for its distinctive appearance and unique feeding habits. It has a long, slender body with a cylindrical shape and a circular mouth filled with sharp teeth. Lampreys are primarily found in freshwater and marine environments across the globe. They are known as parasitic feeders, attaching themselves to the bodies of other fish with their suction-like mouths and feeding on their blood and bodily fluids. However, not all lampreys are parasitic, as some species are non-parasitic and feed on detritus or small invertebrates. Lampreys play an important ecological role by serving as prey for larger fish and contributing to nutrient cycling. With their ancient lineage and distinct characteristics, lampreys provide a fascinating glimpse into the diversity of aquatic life.
