The sea lamprey (Petromyzon marinus) is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". 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.
Only some non-native species are considered invasive. While nearly 200 non-native species have moved into the region and established populations, Lower said scientists are watching another 100 to ...
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.

The mucus and serum of several lamprey species, including the Caspian lamprey (Caspiomyzon wagneri), river lampreys (Lampetra fluviatilis and L. planeri), and sea lamprey (Petromyzon marinus), are known to be toxic, and require thorough cleaning before cooking and consumption. [101] [102]
In the Great Lakes region the sea lamprey is an invasive species. In its original habitat, it had co-evolved as a parasite that did not kill its host. However, in the Great Lakes Region, it acts as a predator and can consume up to 40 pounds of fish in its 12–18 month feeding period. [116]

The Sea Lamprey has become such a big problem since the Lamprey is an invasive species; they must be controlled to keep the ecosystems in check and be given the best ability for survival. [8] Sea Lamprey will be controlled by a specific lampricide known as TFM. TFM kills sea lamprey largely; as the TFM has little to no impact to fish.
