Mammals

From the cheetah's sprint to the red fox raiding a winter hedgerow, this collection answers the questions people actually type about mammals: how fast, how big, how long, and what's on the menu. Each guide focuses on one species or one clear question and answers it fully before moving on. Our standard here is simple: figures are given as honest ranges from well-established natural-history knowledge, wild and captive numbers are separated when they differ, and myths get labeled as myths. If a number is contested or commonly exaggerated, we say so rather than repeat it.
