Covered by a dense tropical forest and surrounded by clear waters,
Nosy Komba is home to a multitude of animals among which :  Makis Macacos, Chameleons, lizards, snakes, spiders, but also sea turtles, rays, dolphins. There are about twenty kinds of batrachians, various reptiles and 19 species of identified birds.

188 sorts of tropical flora can be found all over the island as well as about 70 of medicinal plants used locally as current remedies.

During colonial times, monks of the religious Capucin congregation developed an Arboretum, composed of a number of imported tress from different parts of the world, which several  hurricanes and storms damaged over the years. The ones remaining belong to a reforestation project of 60 ha, managed by "Water and Forests Malagasy”.
