What is the maximal age a Berardius reaches?
An adult Berardius (Berardius bairdii) usually gets as old as 71 years.
Berardiuss are around 396 days in the womb of their mother. When born, they weight 27 grams (0.06 lbs) and measure 6.27 meter (20′ 7″). They are a member of the Ziphiidae family (genus: Berardius). Fully grown, they reach a bodylength of 61.3 cm (2′ 1″).
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.
Four-toothed whales or giant beaked whales are beaked whales in the genus Berardius. They include Arnoux’s beaked whale (Berardius arnuxii, minami-tsuchi) in cold Southern Hemisphere waters, and Baird’s beaked whale (Berardius bairdii, “tsuchi-kujira”) in the cold temperate waters of the North Pacific. A third species, Berardius minimus, (Latin transliteration=”least four-toothed whale”, commonly called “kuro-tsuchi”) was distinguished from B. bairdii in the 2010s.Arnoux’s and Baird’s beaked whales are so similar that researchers have debated whether or not they are simply two populations of the same species. However, genetic evidence and their wide geographical separation has led them to be classified as separate. Lifespan estimates, based on earwax plug samples, indicate these whales can live up to 85 years. At ~4m at birth, growing to ~10m, these are the largest whales belonging to the family Ziphiidae. The kurotsuchi is much smaller, with adult males having a length of ~7m.This article currently largely treats four-toothed whales as monospecific, due to a lack of species-specific information.
