The sea lamprey (Petromyzon marinus) is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". In its original habitats, the sea lamprey coevolved with its hosts, and those hosts evolved a measure of resistance to the sea lampreys.
Sea lamprey is the most sought-after species in Portugal and one of only two that can legally bear the commercial name "lamprey" (lampreia): the other one being Lampetra fluviatilis, the European river lamprey, both according to Portaria (Government regulation no. 587/2006, from 22 June).

Each larva that grows into a juvenile sea lamprey will migrate into Lake Michigan and can kill 40 pounds of fish in its 12- to 18-month feeding period.
Petromyzontidae are a family of lampreys native to the Northern Hemisphere, comprising the vast majority of living lampreys. [1] Petromyzontids have the highest number of chromosomes (164–174) among vertebrates.
The threat to native species is primarily caused by impacts on the food web; however, invasive species also bring dangerous pathogens and physically interfere with existing aquatic life. [2] Invasive species include sea lampreys, zebra mussels, smallmouth bass, European green crab, vase tunicate, and sea squirts.
A major threat to the lake whitefish is an invasive parasite species, the sea lamprey. It is one of a number of species (in addition to the lake trout and lake herring) aggressively attacked by sea lamprey. In Lake Michigan the sea lamprey began to decimate indigenous fish populations in the 1930s and 1940s.
