Are snakehead fish a dangerous invasive species in the USA? Invasive species, whether they are animals, fish or plants, are causing a huge problem around the world. An invasive species can cause huge disruptions to fragile, local ecosystems, as they often have no natural predators in their new habitat, take over territory and food sources required by indigenous animals for survival and sometimes even destroy terrain.
The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land.umans have been introducing snakeheads to nonindigenous waters for over 100 years. In parts of Asia and Africa, the snakehead is considered a valuable food fish, and is produced in aquacultures (fisheries motivation) or by ignorance (as was the case in Crofton, Maryland).
