The Pacific lamprey (Entosphenus tridentatus) is a fish that lives in both fresh and salt water of the family Petromyzontidae that grows up to 76 cm.
Description
The Pacific lamprey is a lamprey of the family Petromyzontidae, an eel-shaped, jawless animal from the north-eastern Pacific. The species grows to about 76 cm and has a naked, eel-shaped body with a round sucking-disc mouth full of horny teeth instead of jaws. It is anadromous: adults live in the sea and run up rivers to spawn, though resident freshwater populations also exist. In the marine phase it is a parasite that attaches with its sucker to larger fishes and rasps body fluids and tissue; the larvae live for years as filter feeders in river sediment. The species is of great cultural and food importance to indigenous peoples and is harmless to humans.
