Bangladesh has many flagship species, mainly in the protected areas, including the Tiger, Asian Elephant and Hoolock Gibbon. Each of these flagship species plays a key role in its respective ecosystems and is necessary to ensuring the delicate ecological balance.

The Tiger is the national animal of both Bangladesh and India, and it is used as a national symbol of both countries.

Many globally threatened birds can be easily viewed in Bangladesh, including notably the White-rumped Vulture, Pallas’s Fish Eagle, Lesser Adjutant and Masked Finfoot.

Although the country has no endemic species of wildlife, the Bostami Softshell Turtle was treated as endemic until in 2007 when it was established that the species also occurs in Assam, India.

Although not globally threatened, the Estuarine Crocodile is threatened nationally and it is treated as a flagship species for the aquatic ecosystem of the Sundarbans. Other than the flagship or threatened species there are many interesting minor species.
