Description
Phractolaemus ansorgii is an unusual African freshwater fish and the only species of the family Phractolaemidae. It lives in forest pools and swamps of West and Central Africa and reaches about 25 cm. The species has a remarkable mouth that can be projected as a small trunk and a swim bladder entirely organised as a lung, with which the fish can breathe air and survive in almost oxygen-free water. It is microphagous, feeding mainly on epiphytes (algae) and detritus. Because of these adaptations the species is sometimes found in extreme, oxygen-poor habitats, such as near lungfish nests.
