Mammals
Mammals are warm-blooded vertebrates that nurse their young with milk and, with a few exceptions, give birth to live offspring. The class Mammalia spans over 5,500 known species — from the 1.5-gram Bumblebee bat to the 180-tonne Blue whale — occupying virtually every habitat on Earth.
About This Section
Mammal profiles on FaunaHub cover species classification, geographic range and preferred habitat, diet and foraging behavior, social structure, reproduction, and conservation status based on IUCN Red List data. Profiles aim to be factually accurate and clearly distinguish between well-established science and areas where research is ongoing or contested.
