Irrawaddy dolphins are more susceptible to human conflict than most other dolphins that live farther out in the ocean. Drowning in gillnets is the main threat to them throughout their range. Between 1995 and 2001, 38 deaths were reported and 74% died as a result of entanglement in gillnets with large mesh sizes. [ 34 ]
The Irrawaddy dolphin shares similar physical characteristics with the beluga whale, but its genetic makeup ties the Irrawaddy dolphin and the killer whale as close relatives of one another. [13] Irrawaddy dolphins have a slate blue to a slate gray color and their bodies can grow up to 180-275 centimeters in length. [14]
It closely resembles the Irrawaddy dolphin (of the same genus, Orcaella) and was not described as a separate species until 2005. The closest relative to the genus Orcaella is the killer whale, Orcinus orca. [citation needed] The Australian snubfin has three colors on its skin, while the Irrawaddy dolphin only has two.

Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea.Close to forty extant species are recognised. They include several big species whose common names contain "whale" rather than "dolphin", such as the Globicephalinae (round-headed whales, which include the false killer whale and pilot whale).
The Irrawaddy dolphin was once placed in the same family, though recent genetic evidence suggests these dolphins belong to the family Delphinidae. [ 10 ] [ 11 ] The narwhal is the only other species within the Monodontidae. [ 12 ]
