1 Hello! Thank you for downloading my Animal Life Cycles learning materials. I create this material for my son who loves animals and loves to learn anything about them. We use this file for our Animal Kingdom study and learning about the different type of Vertebrate animals. To know more on how we use this printable, visit my blog The file contains the life cycle of: Chicken for birds Dog and Kangaroo (mammal with a pouch) for mammals Snake for reptiles Salmon for fish Frog for amphibians Grasshopper, ladybug, butterfly, ant, dragonfly and honey bee for insects The presentation of the life cycle comes in different forms so you can just choose the kind of presentation you like and print it.

6 chicken laying eggs egg hatching A female bird lays eggs with hard shells. Most birds lay their eggs in nests to keep them safe. A parent sits on the eggs to keep them warm. After 21 days, the chick is ready to hatch. It pecks holes in the shell and pushes itself out. Its feathers are wet but they dry quickly and the chick can run about and feed itself within hours. young chicken adult chicken A baby bird is called a chick. They hatch from the eggs and their parents bring them food and care for them until they can look after themselves. Adult hens are ready to begin laying eggs at about 6 months. Young chickens are about 3 months old, and adult hens are ready to begin laying eggs at about 6 months.

7 frogspawn tadpoles Frogs usually reproduce in spring. Frogs are born in the water. The female lays lots of jelly-like eggs called frogspawn or toadspawn. Frog tadpoles hatch from frogspawn. Baby frogs and toads look very different from their parents. They have external gills for breathing under water, and small mouths for sucking up algae. froglet adult frog The tadpoles bodies start to change, ready for them to live out of water as froglets. This process is called Metamorph. When the froglets hop out of the water they look like frogs but still have short tails. A frog is fully developed when it has lost its tail and can live out of water and catch insects. After 1 to 4 years the males and females are ready to breed and their lifecycle starts again.

8 laying eggs eggs hatching A female salmon lays her eggs in a river. Some fish lay thousands of eggs but they do not look after the babies when they hatch. Baby salmon fish hatches from the eggs. When a baby fish hatches, it looks like a little adult. baby salmon adult salmon Baby salmon have food sac attached to them. As they grow, the young salmon swim out to sea to feed and grow. Salmon grow and mature in the ocean. When mature, it swims back to the river and lay their own eggs.

9 laying eggs Most reptiles lay eggs with tough, leathery shells. They lay their eggs on land in holes or nests. Most female snakes lay about 10 to 15 eggs. The baby snake has a sharp tooth that it uses to cut its way out of the eggshell. eggs hatching When some of the baby reptiles hatch, they look like their parents. Newborn snakes do not stay with their parents. They have to find their own food and protect themselves. young snake adult snake Young reptile like this snake feed and grow to become adults. As young snakes grow they shed, or their skin comes off as new skin grows. The male and female snake mate, or make babies. The female snake will make a nest to get ready for the eggs to be laid. She will bury the eggs to protect them.

10 newborn dogs baby dogs All newborn dogs are born blind and deaf until they reach a certain age. They heavily depend on their mother in this period. Senses such as smell, touch and taste begin to develop. During the initial month of the baby dog s lives, there's no need to feed them anything other than the milk they get straight from their mother. young dog adult dog A young dog continues to grow along with his social learning. He will also have high energy levels at this point, and will have also reached his sexual maturity. The adult age of a fully matured dog occurs when he is around 2 years old. His senior years start when he is around 7 years old. During these stages, the dog has become fully matured, independent and responsible.

11 newborn kangaroo baby kangaroo Immediately after birth the newborn kangaroo crawls up the mother's body and enters the pouch. The baby attaches its mouth to one of four teats, which then enlarges to hold the young animal in place. The baby kangaroo drinks milk from its mother and grows bigger inside the mother s pouch. young kangaroo adult kangaroo After several weeks, the joey becomes more active and gradually spends more and more time outside the pouch, which it leaves completely between 7 and 10 months of age. A mature female kangaroo can then start to mate and conceive again.

19 laying eggs Grasshoppers lay their eggs in an oval masses protected by tough overcoat. Many grasshoppers lay their eggs in the fall. After the mother places her eggs in the ground, she covers the hiding place with a gummy substance so that no intruders may work harm to it. eggs hatching Early spring, the eggs are ready to hatch. When the baby grasshopper hatches, it wiggles its way out of its egg. Then it pushes through the egg pod and makes its way up out of the hole. nymphs Grasshoppers are insects with incomplete metamorphosis, which means that the baby grasshopper, as soon as it hatches, is similar in form to its parents. Baby grasshoppers are called nymph. Nymphs eat more than adult grasshoppers. adult grasshopper As the nymph grows, it sheds its exoskeleton (called molting). As it molts, the nymph grow wings. The wings and adult grasshopper is finally formed by the time of the last molt.

20 egg larva Butterflies develop from eggs. Adult butterflies lay their eggs in a suitable host plant (in a leaf. The shells of egg may be slightly ribbed and are sometimes adorned with spines. From eggs, larva issue. This stage is devoted to feeding and to growth. It is the chief business of the larva to eat diligently, to attain maturity as soon as possible. pupa adult butterfly Once the larva has attained its full growth, it changes skin and form and becomes a pupa. take place within the body itself. The pupa of a butterfly is called a chrysalis. After some period, the pupa burst open and from it emerges the adult butterfly equipped with large beautiful wings and always provided with 6 legs and a complex body structure.

21 eggs In spring, the ladybird lays her eggs here and there in plants. The eggs are yellow or orange in color. As soon as the larva hatches, it starts to hunt for aphids and other insects. larva The larva are long and segmented, with six queer short legs that are efficient in clinging around a stem. It is usually black. spotted with orange or yellow. Its business is to crawl around on plants and eat aphids or other insects pupa ladybird This is the pupa stage wherein after the larva shed its skeleton skin several times, it hangs itself up by the rear end of some quiet corner and condenses itself into a sub-globular form. After a few days, the pupa burst open and a full grown ladybird emerges. Newly emerged ladybirds are bright yellow. But once the wing casing hardens, distinctive colour patterns develop.

22 eggs larvae The ant s eggs are very small objects oblong in shape and about the size of a pinpoint. Ant s larvae are translucent creatures and looks like rice grains with one end pointed. pupae ant The pupae are yellowish, covered with a parchment-like sac and resembles grains of wheat. Pale yellowish ant emerges from the pupa and they quickly darken as their exoskleleton matures and hardens. Ants are the longest living of all insects, they live up to 30 years!

23 eggs larvae The queen lays eggs which are mighty tiny. The queen lays a single egg in each cell of the comb that has been cleaned and prepared by the workers to raise new brood. The larvae which now is a little white grub is fed for five days with a special substance secreted by the worker bees called the royal jelly. These larvae cell will then be sealed over and starts to change into pupae. pupae honey bee This is the non-feeding stage. At this stage, the bee is gradually forms its adult structure. First the head and the thorax develops, followed by the wings. The adult bees bites its way out of the capping of its cell and emerges, while leaving the pupal envelope behind. The bee will clean the cell and other cells around it.

24 laying eggs nymph The dragonfly s eggs are laid in the water, in some instances they are simple dropped and sink to the bottom of the water. The nymph is no wise resembles the parent dragonfly. It is dingy little creature with six spider-like legs and no wings. It may remain hidden at the bottom of the pond or cling to water weeds. molt dragonfly Nymphs grow by shedding the skin as fast as it becomes too small and when finally ready to emerge, they crawl up on some object out of the water and molt for the last time. Once it leaves the exuvia (the skin that the nymph left behind, it is fully grown and will hunt for food and begin to look for a mate.
