What is the maximal age a False killer whale reaches?
An adult False killer whale (Pseudorca crassidens) usually gets as old as 22 years.
False killer whales are around 462 days in the womb of their mother. When born, they weight 102 grams (0.22 lbs) and measure 19.1 cm (0′ 8″). They are a member of the Delphinidae family (genus: Pseudorca). Fully grown, they reach a bodylength of 47.2 cm (1′ 7″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The false killer whale (Pseudorca crassidens) is an oceanic dolphin that inhabits oceans worldwide but mainly frequents tropical regions. It was first described in 1846 as a species of porpoise based on a skull, which was revised when the first carcasses were observed in 1861. The name “false killer whale” comes from the similar skull characteristics to the killer whale (Orcinus orca).The false killer whale reaches a maximum length of 6 m (20 ft), though size can vary around the world. It is highly sociable, known to form pods of up to 500 members, and can also form pods with other dolphin species, such as bottlenose dolphins (Tursiops truncatus). Further, it can form close bonds with other species, as well as partake in sexual (including both heterosexual and homosexual) interactions with them. Conversely, the false killer whale has also been known to feed on other dolphins, though it typically eats squid and fish. It is a deep-diving dolphin, with a maximum recorded depth of 927.5 m (3,043 ft); its maximum speed is around 29 km/h (18 mph).The false killer whale easily adapts to captivity and is kept in several aquariums around the world, though its aggression towards other dolphins makes it less desirable. It is threatened by fishing operations, as it can become entangled in fishing gear. It is drive hunted in some Japanese villages. The false killer whale has a tendency to mass strand given its highly social nature, with the largest stranding consisting of 805 beached at Mar del Plata, Argentina. Most of what is known of false killer whale comes from examining stranded individuals.
