The reedfish, ropefish (more commonly used in the United States), or snakefish, Erpetoichthys calabaricus, is a species of fish in the family Polypteridae alongside the bichirs. It is the only member of the genus Erpetoichthys. It is native to fresh and brackish waters in West and Central Africa. The reedfish possesses a pair of lungs in addition to gills, allowing it to survive in very oxygen-poor water. It is threatened by habitat loss through palm oil plantations, other agriculture, deforestation, and urban development
The roundworm, Contracaecum rudolphii, is a parasitic nematode belonging to the family Anisakidae. Fish are by far the main source of infection as they serve as intermediate host of the nematodes. The final hosts are marine mammals (e.g. seals) or piscivorous birds (e.g. cormorants and pelicans). Identification of these nematodes is important in terms of seafood safety and public health, as humans may be infected following consumption of infected seafood.
