mammals
Warm-blooded vertebrates
Mammals are warm-blooded vertebrates that nurse their young with milk produced by mammary glands—the feature that gives the class its name.
Most mammals give birth to live young, though a few like the platypus lay eggs.
Humans, whales, bats, and mice are all mammals.
The word works as both scientific classification and casual grouping: Mammals dominated after the dinosaurs disappeared.
