Family Potamonautidae

The family Potamonautidae contains 138 species in 18 genera. Exclusively freshwater, they are found on the African continent and its offshore islands (including Madagascar and the Seychelles). I was privileged to be able to dive in Lake Malawi and photograph Potamonautes orbitospinus. I found them difficult to photograph, they are primarily nocturnal and ran for cover the instant I shone an aiming light at them.
