The document describes the key characteristics of different types of animals. Mammals have fur or hair, breathe with lungs, and feed their young milk. Birds have two legs, most fly with wings, and hatch from eggs. Fish live only in water, breathe with gills, and are born live or hatch from eggs. Reptiles are land animals with scales, have lungs for breathing, and hatch from eggs. Amphibians usually live first in water and later on land, lay eggs, and have moist skin.
