Although not considered an acrobatic animal, the Irrawaddy dolphin occasionally leaps into the air.
Researchers with the Wildlife Conservation Society estimate that nearly 6,000 Irrawaddy dolphins, marine mammals that are related to orcas or killer whales, were found living in freshwater regions of Bangladesh's Sundarbans mangrove forest and adjacent waters of the Bay of Bengal.
There has been hardly any marine mammal research done in this area up to this point.
Each discovery of Irrawaddy dolphins is important because scientists do not know how many remain on the planet. Prior to this study, the largest known populations of Irrawaddy dolphins numbered in the low hundreds or less.
