More About Amazon River Dolphins:

Amazon river dolphin, also known as the โ€œpink river dolphin or botoโ€, is found in freshwater rivers in the Amazon and Orinoco basins in South America. Unlike marine dolphins, this species has a distinctive body structure perfectly suitable for the turbid river environment. They have a long neck, elongated snout, and teeth that can be shifted to crush the prey. They differ in colour, can turn pink for males, and are generally light grey, especially in the younger stage.

Unlike many other dolphin species, Amazon river dolphins are solitary and do not travel in large pods. They use their flexible necks to search for prey, mainly fish, crustaceans, and even small terrestrial mammals that fall into the water. Their diet and hunting adaptations allow them to thrive in the complex ecosystem of the Amazon basin.

These animals exhibit various behaviours, including play and other interactions, as well as hunting, occasionally. They also share common responses with people, especially within the territories where people consider them holy or that they are protective spirits of the river.

Status of Amazon River Dolphins

IUCN Status: Endangered

Amazon river dolphins have been historically widespread in the regions they inhabit. However, the population of the Amazon River dolphin is threatened by habitat loss, water pollution, accidental entanglement in fishing nets, dam construction and mercury found from mining activities too. 

Due to these factors, the IUCN has listed the Amazon river dolphin under the threatened species category as endangered. Present conservation measures are being employed to ensure that the last populations of these species are saved but the future of this extraordinary freshwater cetacean remains bleak.
