Dolphin sanctuaries to open in Bangladesh

In three districts of Bangladesh, reserves will be created to restore populations of unique river dolphins. The habitats of the largest number of these animals have been allocated under protected areas. Fishermen will not be allowed to fish here.

The number of river Gangetic (Platanista gangetica) and Irrawaddy (Orcaella brevirostris) dolphins listed in the international Red Book is constantly decreasing due to the disappearance of their usual habitat, as well as the accidental death of these animals in fishing nets.

The Gangetic dolphin is very different from other species of these animals. Instead of a dorsal fin, it has a low triangular hump. In length, this mammal reaches 2.5 meters and weighs up to 90 kilograms. Due to living in muddy river water, the animal is almost blind.

The Irrawaddy is the only beakless dolphin with a wide and short spherical head. Its length can reach 2.75 meters, and body weight – up to 140 kilograms. These animals live in small groups of 3-5 individuals.

According to RIA Novosti, reserves to preserve the natural habitat of these river mammals will appear in the areas of Dhangmari, Chandpai and Dudhmukhi, located in the eastern part of the Sundarbans, the largest mangrove forest on earth.
