📖 Overview

Obligate air-breathing ; Protopterus dolloi is not aestivating in cocoons during the dry-season, because the habitat in which it lives is never completely dry ; although it never lost the capability to aestivate . Therefore, the tunnel which it digs is not for hibernation but functions as a protected chamber during reproduction, which takes place in the dry season . The male guards the eggs and larvae in the nest, which is built in the mud of the swamps, while the females can be found in the open water of the rivers . The food of Protopterus dolloi are fishes and insects, but during the time of reproduction its food is more vegetarian .
