The Class Channidae is a family of freshwater fishes that are commonly referred to as snakeheads. Other synonyms for this class include Northern snakeheads, giant snakeheads, and striped snakeheads. They belong to the Chordata phylum and are native to parts of Asia and Africa. Snakeheads have a distinct appearance with elongated bodies and sharp-toothed jaws. They are classified as invasive species in some parts of the world as they have been introduced to new environments and have negatively impacted local ecosystems. Despite their controversial status, snakeheads have been used in traditional medicine and cuisine in some cultures.
