American River Diver Spots Parasitic Vampire Fish That Feed Off Sharks On 5/20/21 at 11:50 AM EDT A veteran diver in California has spotted a strange vampire fish, or lamprey, in a Sacramento river. On Tuesday, diver Karl Bly spotted two pacific lampreys in the American River, which runs for 30 miles from the Sierra Nevada mountains to where it meets Sacramento River. He wrote on Facebook that this is the second lamprey he has seen in 30 years. It looks like some sea creature from the deep, Bly said. These jawless, parasitic eel-like fish are characterized by their large sucking disk mouth, which features sharp teeth on a tongue that resembles a file. To feed, they attach their disk to other fish, and grate their scales and skin in order to devour their body fluids. Like leeches, they release an enzyme that stops their victim s blood from clotting. This way of feeding often means the fish they feed on will die due to blood loss or because of infection.
