A "lamper eel" isn't actually an eel, but a type of lamprey! π² Lampreys are jawless fish characterized by a toothed, funnel-like sucking mouth. They use this to latch onto other fish and suck their blood β kind of like a vampire fish. π§ They live in both fresh and saltwater environments. Unlike true eels, lampreys have a more primitive body structure. Think of them as living fossils, representing an ancient lineage of fish.
