In their freshwater habitat they are apex predators and gatherings depend more on food sources and habitat availability than in oceanic dolphins where protection from larger predators is necessary. [26] Captive studies have shown that the Amazon river dolphin is less shy than the bottlenose dolphin, but also less sociable. It is very curious ...
River dolphins are thought to have relictual distributions, that is, their ancestors originally occupied marine habitats, but were then displaced from these habitats by modern dolphin lineages. [ 12 ] [ 13 ] Many of the morphological similarities and adaptations to freshwater habitats arose due to convergent evolution ; thus, a grouping of all ...

The dolphins were protected in Cambodia and Laos and explosive fishing and use of gillnets were restricted in many of the Irrawaddy dolphin's habitats ...
