The "sea lamprey" is a jawless fish with a sucker-like mouth and sharp teeth. 🧛 It's known for its parasitic lifestyle, attaching to other fish and feeding on their blood. They migrate from saltwater to freshwater to spawn, a process called anadromous migration. Sea lampreys are considered an invasive species in the Great Lakes, where they have caused significant ecological damage. Think of the sea lamprey as a vampire of the fish world. 🐟
