Polar bear
2.5 m - Length; defined specimen.
A polar bear is a large carnivorous mammal adapted to life on Arctic sea ice, mainly hunting seals.
A chosen 2.5 m, 500 kg adult male.
Defined examples — our methodologyThe length of a polar bear is about 1.43 times the height of a human. Selected basis: a defined specimen of Polar bear; an example for Human; approximate values.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.
