Mammal

Explore the warm-blooded world of mammals — from the smallest shrew to the largest whale.

Mammals share a set of defining traits that set them apart: warm blood, hair or fur, and mothers that produce milk for their young. But within those shared features lies extraordinary diversity. The blue whale is the largest animal ever to have lived, while the bumblebee bat weighs less than a penny. Mammals have conquered every habitat — cheetahs sprint across savannas, dolphins surf ocean waves, bats navigate by echolocation in total darkness, and moles tunnel through the earth. Many mammals are among the most intelligent animals known, with complex social structures, tool use, and even cultural traditions passed between generations.
