Description

The Far Eastern brook lamprey is a lamprey (Petromyzontidae) from East Asia. It is not a true fish but a jawless vertebrate (Agnatha), with an eel-like, slimy body and a round, sucker-shaped mouth without jaws. It lives in rivers, brooks, ponds and lakes, including brackish water. Unlike many lampreys this is a non-parasitic brook lamprey: the adults do not feed and reproduce shortly after metamorphosis, while the worm-like larvae (ammocoetes) feed for years buried in sediment on detritus and microorganisms. The species is harmless to humans.
