It is hard to guess what a Irrawaddy dolphin weights. But we have the answer:
An adult Irrawaddy dolphin (Orcaella brevirostris) on average weights 190 kg (418.88 lbs).
The Irrawaddy dolphin is from the family Delphinidae (genus: Orcaella). When reaching adult age, they grow up to 2.5 meter (8′ 3″). Usually, Irrawaddy dolphins have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The Irrawaddy dolphin (Orcaella brevirostris) is a euryhaline species of oceanic dolphin found in discontinuous subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia.
