Why do lampreys attach to other fish?
AnimalsParasitism
Quick Answer
Lampreys are parasitic on many species and feed by using their suction-like mouth and tooth-covered disc. They rasp away tissue and drink blood and body fluids.
The Full Story
Many lamprey species attach to other fish with a circular mouth lined with horny teeth. Using a rasping tongue, they cut into the host’s skin and feed on blood and other bodily fluids. This parasitic lifestyle is most famous in some marine and freshwater lampreys, though not all lampreys are parasitic. Their attachment strategy makes them effective but often unpopular predators. Lampreys are ancient jawless vertebrates, which makes their feeding biology especially interesting to scientists.
