It is hard to guess what a Stejneger’s beaked whale weights. But we have the answer:
An adult Stejneger’s beaked whale (Mesoplodon stejnegeri) on average weights 4800 kg (10582.18 lbs).
The Stejneger’s beaked whale is from the family Ziphiidae (genus: Mesoplodon). When reaching adult age, they grow up to 6.09 meter (20′ 0″).
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.
Stejneger’s beaked whale (Mesoplodon stejnegeri), also known as the Bering Sea beaked whale or the saber-toothed whale, is a relatively unknown member of the genus Mesoplodon inhabiting the northern North Pacific Ocean. Leonhard Hess Stejneger collected the type specimen (a beach-worn skull) on Bering Island in 1883, from which Frederick W. True provided the species’ description in 1885. In 1904, the first complete skull (from an adult male that had stranded near Newport, Oregon) was collected, which confirmed the species’ validity. The most noteworthy characteristic of the males is the very large, saber-like teeth, hence the name.
