The Anjajavy Forest is named for a kind of "Salvadora" species, the "jajavy" tree, which might be endemic only to the forest itself. Abundant diurnal lemurs that are found here include the Coquerel's sifaka and the common brown lemur. Three nocturnal species of mouse lemur are seen, but their precise species are yet to be documented. A large variety of birds are present including the endangered Madagascar fish eagle, which has four (of the approximately 99 known) breeding pairs resident in Anjajavy Forest. Other birdlife present are the sacred ibis, crested coua, kingfishers and Madagascar wagtail. Butterflies include the magpie crow. Numerous lizards, chameleons and snakes populate the forest and are easily seen from the sparse trail network.
