Life Cycle of a butterfly egg Larva (caterpillar) pupa adult

Egg When a female butterfly is ready to lay its eggs, it flies around to find the right plant. Then it flies off and leaves the eggs to hatch on their own Back

Larva Each egg hatches into a larva. The larva is the young of an insect. The larva of a butterfly has a special name. It is called a caterpillar. Back

Pupa The caterpillar has now changed into a pupa. The pupa may look inactive on the outside, but inside, amazing changes are taking place. Back

Adult When the case finally breaks open, a beautiful butterfly comes out of it. The butterfly spreads its wings to dry. Then it takes off on its first flight. Back

Fish Surface Sea birds prey on shoals of fish; mammals, such as dolphins and whales, surface for air.

Bird Toucans The large serrated bill of the toucan is adapted for grasping and tearing fruit. It helps the bird reach fruit on the end of thin twigs that cannot support its weight. Once collected, food has to be moved from the tip of the bill into the bird's throat- a task that is achieved with a quick backward toss of the head. Toucans help disperse the seeds of some trees by eating them and passing them through their bodies, as do many other forest birds, such as parrots

Mammal Aquatic Mammals Three groups of mammals have adapted to aquatic life, developing a streamlined body and the ability to stay underwater for long periods (although all of them return to the surface to breathe). The largest group are whales and dolphins. Like whales, seals and sea lions rely on subcutaneous fat to keep warm, but they have retained their fur, which is kept waterproof by an oily secretion. Sirenians (the manatees and dugong) live in warm coastal waters and estuaries and are the only herbivorous aquatic mammals.
