The oldest recorded Irrawaddy dolphins, all of which were found dead in fishing nets, were estimated to be 28 years old. Several individuals of this age have been found, all entangled in nets, so it is believed that Irrawaddy dolphins can live longer. Due to the small population size of Irrawady dolphins and subsequent difficulty in tracking the species, no further information is known regarding average lifespan.
