It is hard to guess what a Berardius weights. But we have the answer:
An adult Berardius (Berardius bairdii) on average weights 11390 kg (25110.62 lbs).
The Berardius is from the family Ziphiidae (genus: Berardius). They can live for up to 71 years. When reaching adult age, they grow up to 14.9 cm (0′ 6″).
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.

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.
