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.
