There are 121 species of mammals (including 5 marine species), 690 birds (380 resident, 209 winter visitor, 11 summer visitor and 88 vagrant), 158 reptiles (including 19 marine species) and 53 amphibians in Bangladesh. These include some species whose occurrences are predicted on the basis of their known occurrence very close to Bangladesh.

New species are added every year in the national checklist. There are no wildlife species that occur only in Bangladesh (endemic), because Bangladesh has never been isolated from Mainland Asia and the habitat types found in Bangladesh are also available in the neighboring countries.
