Clarias maclareni is a catfish that lives only in one lake in Cameroon. This fish can breathe air and sometimes move on moist land using its pectoral fins.
Clarias maclareni differs from related catfishes by a special organ for air breathing and the ability to go on land. It is important for nature as a predator that regulates the population of small animals in the lake.
Immature form that undergoes metamorphosis before adulthood.
