It is hard to guess what a Pygmy killer whale weights. But we have the answer:
An adult Pygmy killer whale (Feresa attenuata) on average weights 170 kg (374.79 lbs).
The Pygmy killer whale is from the family Delphinidae (genus: Feresa). When reaching adult age, they grow up to 50 cm (1′ 8″). Usually, Pygmy killer whales 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 pygmy killer whale (Feresa attenuata) is a poorly known and rarely seen oceanic dolphin. It derives its common name from sharing some physical characteristics with the killer whale. It is the smallest cetacean species that has “whale” in its common name. Although the species has been known to be extremely aggressive in captivity, this aggressive behavior has not been observed in the wild.The species had been described by John Gray in 1874, based on two skulls identified in 1827 and 1874. The next recorded sighting was in 1952 which led to its formal naming by Japanese cetologist Munesato Yamada in 1954.
