  6. 6. Information about a life cycle of a ButterflyButterflies in their adult stage can live from a week to nearly ayear depending on the species. Many species have long larval lifestages while others can remain dormant in their pupa or eggstages and thereby survive winters.Butterflies may have one or more broods per year. The numberof generations per year varies from temperate to tropical regionswith tropical regions showing a trend towards multivoltinism.
  7. 7. •Life Cycle Of Frog.
  8. 8. Information about life cycle of a Frog.They usually begin life in water as eggs. A ball of jelly surroundseach of the eggs, which are compiled together in a clump calledspawn. After 10 days the tadpole hatches and wiggles out of thejelly ball. These tadpoles breathe through gills that are on theoutside. Gradually the back legs begin to appear and the outsidegills begin to disappear. One week after the legs form thetadpole develops lungs and can breathe our air. Then in 10 to 12weeks the tadpole develops front legs. After its front legs formthe tadpole does not eat, but absorbs its tail for food.At about three and a half months it becomes a froglet and caneat small bugs. It now spends most of its time out of the water.Once the frog finishes growing and has lost its tail, it isconsidered an adult frog. Frogs are amphibians that can live onland or water.
  9. 9. •Life cycle of snake.
  10. 10. Information about life cycle of a Snake.Most female snakes lay about 10 to 15 eggs. The yolk of theegg feeds the baby snake inside.The baby snake has a sharptooth that it uses to cut its way out of the eggshell. Newbornsnakes do not stay with their parents. They have to find theirown food and protect themselves. Baby snakes are usuallyabout a quarter of the size of their parents. As young snakesgrow they shed, or their skin comes off as new skin grows. Afemale snake will leave a scent smell on the trail as shemoves.The male snake will smell the scent and find the femalesnake. The male and female snake mate, or make babies.Themale snake fertilizes the eggs.The female snake will make anest to get ready for the eggs to be laid.She will bury the eggsto protect them.
  11. 11. •Life cycle of a Hen.
  12. 12. Information about life cycle of a HenWhen an egg is laid, a chick starts to grow inside. Theeggs need to be kept warm. The hen will sit on top of hereggs to keep them warm. The yolk inside the egg has foodthat helps the chick grow. When a chick is strong enough,it hatches from its egg.A chick has a lump on its beakcalled an egg tooth. It uses its egg tooth to make holesaround the shell. Baby chicks learn about what is good toeat by pecking. Sometimes they even peck at their owntoes. A female chicken is called a hen. A male chicken iscalled a rooster. Most hens will lay about two eggs a day.In the winter hens stop laying eggs until spring. Chickenscan live as long as 10-12 years.
  13. 13. •Life cycle of a Horse.
  14. 14. Information about life cycle of a Horse.A newborn horse is called a foal. The mother feedsthe foal her warm milk for a year. Foals also eatgrass and hay after a few weeks. Foals can walk, butthey have wobbly legs at first. When a horse is oneyear old, it is called a yearling. A female yearling iscalled a filly and a male yearling is called a colt.Ayearling starts to learn how to carry a rider. Ayearling is usually the same size as its parents. Afemale horse is called a mare. A male horse iscalled a stallion.A mare will mate with a stallion inthe springtime. A female horse carries a baby insideher for almost a year.
  15. 15. •Life cycle of a Kiwi.
  16. 16. Information about life cycle of a Kiwi.Adult kiwi set up a territory, prepare a nestingburrow and then mate. When the femaleproduces her huge egg (or two), in some speciesonly the male that incubates it. When the egghatches, a fully feathered chick emerges to faceits first few days of life.
  17. 17. •Life cycle of a Tiger.
  18. 18. Information about life cycle of a Tiger.A tiger cub weighs about 1.1 kg, is born blind and deaf andentirely dependent of its mother. After a few weeks, cubsbegin to travel with their mother and she will teach them theart of be a tiger. At the age of 12 months, they begin toexplore their territory more often, but still depend on theirmother. At about 2-3 years old, the young adults leave theirmothers and begin a relatively lonely life.When the femalesare about 3-4 years, they have their first litter, but the malesdont mate until 4-5 years old, and only if they can get aterritory of their own. The males mostly fight for the territoryand the safety of there females and cubs.The life of a tiger is hard, but they become the most powerfulpredator of his territory. The females have a life span of about15 years while the males have a life span of about 10 years.
  19. 19. •Life cycle of a Cheetah.
  20. 20. Information about life cycle of a Cheetah.• A cheetah life cycle can be fully explained by an expert; its rare to find american farms that have one; if you ever visit an african farm, theres a slim chance youll see one. These wild felines weigh about 35-60 kilograms. Length of their body is 2.5-3 meters long including tail. Their shoulder height is 75-90 centimeters. In the wild they live up to 12 years, in captivity they can live up to 17 years.

  21. 21. •Life cycle of Fire Ant.
  22. 22. Information about life cycle of a Fire AntThe life cycle of the ant consists of four stages: egg, larva,pupa, and adult. Fertilized eggs produce female ants (queens,workers, or soldiers); unfertilized eggs produce male ants.Anteggs are oval shaped and tiny (they are on the order of 1 mmlong, but the queens egg is many times larger).The worm-likelarvae have no eyes and no legs; they eat food regurgitated byadult ants. The larvae molt (shed their skin) many times asthey increase in size.After reaching a certain size, the larvaspins a silk-like cocoon around itself (against a solid object,like the wall of the chamber) and pupates. During this timethe body metamorphoses (changes) into its adult form.The pupa emerges as an adult. The entire life cycle usuallylasts from 6 to 10 weeks. Some queens can live over 15 years,and some workers can live for up to 7 years.
  23. 23. •Life cycle of a Crab.
  24. 24. Information about life cycle of a Crab.Blue crabs start their lives as tiny zoea, floating inthe ocean waters. While growing into the megalopastage, the crabs drift back into the Chesapeake Bay,where they grow into juvenile crabs and, eventually,adults. The blue crabs life cycle is also closelyrelated to its migration patterns. Lets take a closerlook at the stages the life of the blue crab.Moveyour mouse over the image or use the descriptionsbelow to learn more about each stage in the lifecycle.
  25. 25. •Life cycle of a Mosquito.
  26. 26. Information about life cycle of a Mosquito.Mosquitoes undergo complete metamorphosis; they go through fourdistinct stages of development during a lifetime. The four stages areegg, pupa, larva, and adult. The full life-cycle of a mosquito takesabout a month. After drinking blood, adult females lay a raft of 40 to400 tiny white eggs in standing water or very slow-moving water.Within a week, the eggs hatch into larvae (sometimes called wrigglers)that breathe air through tubes which they poke above the surface ofthe water. Larvae eat bits of floating organic matter and each other.Larvae molt four times as they grow; after the fourth molt, they arecalled pupae . Pupae (also called tumblers) also live near the surface ofthe water, breathing through two horn-like tubes (called siphons) ontheir back. Pupae do not eat.An adult emerges from a pupa when the skin splits after a few days.The adult lives for only a few weeks.
  27. 27. •Life cycle of a Fish.
  28. 28. Information about life cycle of a Fish.The female fish will lay about 25 eggs, but only thehealthy ones will grow up . Sometimes the adult goldfisheat the eggs. If you have a fish tank, you should take theadults out so they are away from the eggs. The eggsusually hatch in about 5 days. A baby goldfish is called afry. Once they hatch from the egg, they stay attached tothe plants for about 2 days. When the fry start to swimthey should be fed. Goldfish need a lot of room to swimaround. They also need plants so they can hide and laytheir eggs. The female goldfish rubs against plants andsprays out her eggs.The male goldfish sprays the eggs sothey fertilize and start to grow baby fish.
  29. 29. •Life cycle of a Crocodile.
  30. 30. Information about life cycle of a Crocodile.The female crocodile digs a hole a couple of yards fromthe river bank and up to 20 inches deep, and laysbetween 25 and 80 eggs. Multiple females may nest closetogether. Nostrils, eyes, and ears are situated on the topsof their head, so the rest of the body can remainconcealed underwater.Once they are hatched, the femalemay lead the hatchlings to water, or even carry themthere, in her mouth. One man is carrying four babycrocodiles.The crocodile is the largest African crocodilian,reaching lengths of up to 16 feet or rarely up to 20 feet.Good sized males weigh 1,100 pounds and trulyexceptional specimens may exceed 2,465 pounds.
  31. 31. •Life cycle of a Mouse.
  32. 32. Information about life cycle of a Mice.• The gestation period for a house mouse is 18- 21 days. Mice are born blind and hairless. Sexual maturity is reached in 35 days. The female will average 8 litters per year, each litter averaging 5 to 8 pups. 24-48 hours after giving birth the female again is in heat.
  33. 33. •Life cycle of a penguin
  34. 34. Information about life cycle of a Penguin.• The life cycle of a penguin is: First, Every year male and female penguins get together to mate. The penguin mother laid one to two eggs in a nest. The mother and father take turn keeping the egg warm. The egg hatches in one to two months depending on what kind. A baby chick comes out. The chick grows up and finds a mate which it keeps for life.Then life cycle of a penguin is: First, Every year male and female penguins get together to mate. The penguin mother laid one to two eggs in a nest. The mother and father take turn keeping the egg warm. The egg hatches in one to two months depending on what kind. A baby chick comes out. The chick grows up and finds a mate which it keeps for life.
  35. 35. Life cycle of a •Salamender.
  36. 36. Information about life cycle of a Salamender.Roughly two hundred eggs are laid by the female, in small batches. Theeggs are attached to sticks or pond plants, enclosed in a round, jelly-like coating, and left to hatch. The adults leave the pond and the eggshatch in around thirty days.Salamander young are born with the abilityto look after themselves. Young salamanders have gills to allow themto breathe underwater and hunt for tiny creatures that live in thewater. They also have strong tails, good eyesight and a fully workingmouth.At about three weeks old, a salamanders legs start to grow.The back legs develop first, but there is little time difference betweenarrival of back and front legs. The legs allow the salamander to crawlalong the bottom of the pool, but it can also move using its tail fin.At around two months old, salamanders change to their adult shape.They develop lungs instead of gills, enabling them to live on land, losttheir tail fin and attain their adult coloring. It will take around twoyears for them to reach their full adult length, at which point they willreturn to the water to mate.
  37. 37. •Life cycle of a Snail.
  38. 38. Information about life cycle of a Snail.The reproduction process of the snail is one that has someunusual patterns to it when compared to that of other landanimals.In other ways though the process is the same as whatyou would expect. Learning more about this process will helpyou to see why there are often concerns about snails andother offspring being able to survive in the future. It takesthem about two years to be mature.Land snails engage invarious types of courting rituals to attract mates. They can lastfor a couple of hours or half a day. They don’t make sounds tocall out to each other like many types of animals do. It maysurprise you to learn that snails don’t have the ability to hear.So they use touching as a way of courting. They may covereach other in slime that they produce from their bodiesbefore mating.
  39. 39. •Life cycle of Jellyfish.
  40. 40. Information about life cycle of a Jellyfish.Most scyphozoan jellyfishes—including most of the large jellyfish with which manypeople are familiar—have a two part life cycle: free-swimming medusa and bottom-dwelling polyp (although there are notable exceptions). The free-swimming medusa(the part we call "a jellyfish") is either female or male and produces eggs or spermwhich combine to produce a larva, called a planula (plural = planulae). The planulaswims through the water to find a suitable place to settle, i.e. attach itself to a surface.In the marine lakes, Mastigias planulae settle on the surface (typically the sides orunderneath) of rocks, rotting logs, and decaying leaves that accumulate around thelakes side in the poorly oxygenated (but not anoxic) waters at intermediate depths.The planula metamorphoses into a sessile (i.e. fixed-position), usually benthic (i.e.bottom dwelling) polyp called a scyphistoma and it is the scyphistoma, still attachedto the surface on which the planula settled, that produces a new free-swimmingmedusa. The process by which new medusae are produced is called strobilation andinvolves metamorphosis of the end of a scyphistoma into an ephyra, an immaturemedusa, that subsequently detaches and swims away. Depending on the species, asingle polyp may produce one or many ephyrae all at once, over a period of time, or atdifferent intervals. The ephyra subsequently develops into a mature medusa over aperiod of weeks to months.
  41. 41. •Life cycle of a housefly.
  42. 42. Information about life cycle of a Housefly.The housefly life cycle closely mirrors that of mostinsects: a basic cycle that begins with an egg, thendevelops through a larva phase, a pupa phase, and finally,into an adult. During a warm summer -- optimalconditions for a housefly -- the cycle, from fertilized eggto adult, spans a mere seven to 10 days.After a malehousefly chases down and fertilizes a female counterpart,shes ready to lay her eggs. Houseflies are solitarycreatures. Like the rest of the insect world, males andfemales do not stick together after mating and, unlikenesting insects, females do not care for or protect eggs.Females simply leave the eggs where they will be safefrom predators and have plenty to eat upon hatching.
  43. 43. •Life cycle of a Koala.
  44. 44. Information about life cycle of a Koala.Koalas breed once a year and mate from August to January. At this time theytend to move outside their normal territories looking for a mate. The malehas a deep, guttural call and the female a high pitched catlike voice. The malehas an oily gland on the centre of his chest which emits a strong odour. Herubs his scent against tree trunks and limbs to mark his territory. When afemale is 2 years old she is ready to mate. Males are capable of reproducingat 2 years of age but often not up to competing against older, larger males.The female comes on heat for only a few days and only then she will displayher readiness for the male. 35 days after mating the female gives birth to asingle Joey.Occasionally twins are reported but a single young is the mostcommon. At birth the Joey weighs less than 1 gram, has no fur, their eyes andears are closed and are the size of a peanut. On average koalas on mainlandAustralia tend to produce one young every two years. After birth the furlessJoey makes its way, unaided, into the mother’s vertically opening pouch. Itattaches itself to one of the 2 teats and remains in the pouch forapproximately six months. During this time it develops slowly, and at about22 weeks the eyes open and it begins to peep out of the pouch
