Kinds of animals and their habitats

An animal’s habitat is the place where it lives, feeds and raises young. Animals adapt to their habitat; this is called adaptation. Land-air animals have organs for taking oxygen from air, and their bodies are covered with skin, feathers or shells that protect from sun and drying out. In water, fish breathe with gills, have smooth, scaly bodies and a swim bladder. Mammals such as dolphins live in water but breathe with lungs and come to the surface. In soil there is little oxygen and light: mostly tiny invertebrates live there; animals such as the mole have weak eyes but a strong sense of smell and touch, and limbs adapted for digging. Some animals use several habitats: a frog breathes with lungs on land and through its skin in water.
