Butterfly

7. Information about a life cycle of a
Butterfly
Butterflies in their adult stage can live from a week to nearly a
year depending on the species. Many species have long larval life
stages while others can remain dormant in their pupa or egg
stages and thereby survive winters.
Butterflies may have one or more broods per year. The number
of generations per year varies from temperate to tropical regions
with tropical regions showing a trend towards multivoltinism.

8. •Life Cycle Of
Frog.

10. Information about life cycle of a Frog.
They usually begin life in water as eggs. A ball of jelly surrounds
each of the eggs, which are compiled together in a clump called
spawn. After 10 days the tadpole hatches and wiggles out of the
jelly ball. These tadpoles breathe through gills that are on the
outside. Gradually the back legs begin to appear and the outside
gills begin to disappear. One week after the legs form the
tadpole develops lungs and can breathe our air. Then in 10 to 12
weeks the tadpole develops front legs. After its front legs form
the tadpole does not eat, but absorbs its tail for food.
At about three and a half months it becomes a froglet and can
eat small bugs. It now spends most of its time out of the water.
Once the frog finishes growing and has lost its tail, it is
considered an adult frog. Frogs are amphibians that can live on
land or water.

11. •Life cycle of
snake.

13. Information about life cycle of a Snake.
Most female snakes lay about 10 to 15 eggs. The yolk of the
egg feeds the baby snake inside.The baby snake has a sharp
tooth that it uses to cut its way out of the eggshell. Newborn
snakes do not stay with their parents. They have to find their
own food and protect themselves. Baby snakes are usually
about a quarter of the size of their parents. As young snakes
grow they shed, or their skin comes off as new skin grows. A
female snake will leave a scent smell on the trail as she
moves.The male snake will smell the scent and find the female
snake. The male and female snake mate, or make babies.The
male snake fertilizes the eggs.The female snake will make a
nest to get ready for the eggs to be laid.She will bury the eggs
to protect them.

14. •Life cycle of a
Hen.

16. Information about life cycle of a Hen
When an egg is laid, a chick starts to grow inside. The
eggs need to be kept warm. The hen will sit on top of her
eggs to keep them warm. The yolk inside the egg has food
that helps the chick grow. When a chick is strong enough,
it hatches from its egg.A chick has a lump on its beak
called an egg tooth. It uses its egg tooth to make holes
around the shell. Baby chicks learn about what is good to
eat by pecking. Sometimes they even peck at their own
toes. A female chicken is called a hen. A male chicken is
called a rooster. Most hens will lay about two eggs a day.
In the winter hens stop laying eggs until spring. Chickens
can live as long as 10-12 years.

17. •Life cycle of a
Horse.

19. Information about life cycle of a Horse.
A newborn horse is called a foal. The mother feeds
the foal her warm milk for a year. Foals also eat
grass and hay after a few weeks. Foals can walk, but
they have wobbly legs at first. When a horse is one
year old, it is called a yearling. A female yearling is
called a filly and a male yearling is called a colt.A
yearling starts to learn how to carry a rider. A
yearling is usually the same size as its parents. A
female horse is called a mare. A male horse is
called a stallion.A mare will mate with a stallion in
the springtime. A female horse carries a baby inside
her for almost a year.

20. •Life cycle of a
Kiwi.

22. Information about life cycle of a Kiwi.
Adult kiwi set up a territory, prepare a nesting
burrow and then mate. When the female
produces her huge egg (or two), in some species
only the male that incubates it. When the egg
hatches, a fully feathered chick emerges to face
its first few days of life.

23. •Life cycle of a
Tiger.

25. Information about life cycle of a Tiger.
A tiger cub weighs about 1.1 kg, is born blind and deaf and
entirely dependent of its mother. After a few weeks, cubs
begin to travel with their mother and she will teach them the
art of be a tiger. At the age of 12 months, they begin to
explore their territory more often, but still depend on their
mother. At about 2-3 years old, the young adults leave their
mothers and begin a relatively lonely life.When the females
are about 3-4 years, they have their first litter, but the males
don't mate until 4-5 years old, and only if they can get a
territory of their own. The males mostly fight for the territory
and the safety of there females and cubs.
The life of a tiger is hard, but they become the most powerful
predator of his territory. The females have a life span of about
15 years while the males have a life span of about 10 years.

26. •Life cycle of a
Cheetah.

28. Information about life cycle of a Cheetah.
• A cheetah life cycle can be fully explained by an
expert; it's rare to find american farms that have
one; if you ever visit an african farm, there's a
slim chance you'll 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. A cheetah life cycle can be fully

farms that have one; if you ever visit an african
farm, there's a slim chance you'll see one.

29. •Life cycle of Fire
Ant.

31. Information about life cycle of a Fire Ant
The 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.Ant
eggs are oval shaped and tiny (they are on the order of 1 mm
long, but the queen's egg is many times larger).The worm-like
larvae have no eyes and no legs; they eat food regurgitated by
adult ants. The larvae molt (shed their skin) many times as
they increase in size.After reaching a certain size, the larva
spins a silk-like cocoon around itself (against a solid object,
like the wall of the chamber) and pupates. During this time
the body metamorphoses (changes) into its adult form.
The pupa emerges as an adult. The entire life cycle usually
lasts from 6 to 10 weeks. Some queens can live over 15 years,
and some workers can live for up to 7 years.

32. •Life cycle of a
Crab.

34. Information about life cycle of a Crab.
Blue crabs start their lives as tiny zoea, floating in
the ocean waters. While growing into the megalopa
stage, the crabs drift back into the Chesapeake Bay,
where they grow into juvenile crabs and, eventually,
adults. The blue crab's life cycle is also closely
related to its migration patterns. Let's take a closer
look at the stages the life of the blue crab.Move
your mouse over the image or use the descriptions
below to learn more about each stage in the life
cycle.

35. •Life cycle of a
Mosquito.

37. Information about life cycle of a Mosquito.
Mosquitoes undergo complete metamorphosis; they go through four
distinct stages of development during a lifetime. The four stages are
egg, pupa, larva, and adult. The full life-cycle of a mosquito takes
about a month. After drinking blood, adult females lay a raft of 40 to
400 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 of
the water. Larvae eat bits of floating organic matter and each other.
Larvae molt four times as they grow; after the fourth molt, they are
called pupae . Pupae (also called tumblers) also live near the surface of
the water, breathing through two horn-like tubes (called siphons) on
their 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.

38. •Life cycle of a
Fish.

40. Information about life cycle of a Fish.
The female fish will lay about 25 eggs, but only the
healthy ones will grow up . Sometimes the adult goldfish
eat the eggs. If you have a fish tank, you should take the
adults out so they are away from the eggs. The eggs
usually hatch in about 5 days. A baby goldfish is called a
fry. Once they hatch from the egg, they stay attached to
the plants for about 2 days. When the fry start to swim
they should be fed. Goldfish need a lot of room to swim
around. They also need plants so they can hide and lay
their eggs. The female goldfish rubs against plants and
sprays out her eggs.The male goldfish sprays the eggs so
they fertilize and start to grow baby fish.

41. •Life cycle of a
Crocodile.

43. Information about life cycle of a
Crocodile.
The female crocodile digs a hole a couple of yards from
the river bank and up to 20 inches deep, and lays
between 25 and 80 eggs. Multiple females may nest close
together. Nostrils, eyes, and ears are situated on the tops
of their head, so the rest of the body can remain
concealed underwater.Once they are hatched, the female
may lead the hatchlings to water, or even carry them
there, in her mouth. One man is carrying four baby
crocodiles.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 truly
exceptional specimens may exceed 2,465 pounds.

44. •Life cycle of a
Mouse.

46. 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.

47. •Life cycle of a
penguin

49. 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

50. Life cycle of a
•
Salamender.

52. Information about life cycle of a
Salamender.
Roughly two hundred eggs are laid by the female, in small batches. The
eggs 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 eggs
hatch in around thirty days.Salamander young are born with the ability
to look after themselves. Young salamanders have gills to allow them
to breathe underwater and hunt for tiny creatures that live in the
water. They also have strong tails, good eyesight and a fully working
mouth.At about three weeks old, a salamander's legs start to grow.
The back legs develop first, but there is little time difference between
arrival of back and front legs. The legs allow the salamander to crawl
along 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, lost
their tail fin and attain their adult coloring. It will take around two
years for them to reach their full adult length, at which point they will
return to the water to mate.

53. •Life cycle of a
Snail.

55. Information about life cycle of a Snail.
The reproduction process of the snail is one that has some
unusual patterns to it when compared to that of other land
animals.In other ways though the process is the same as what
you would expect. Learning more about this process will help
you to see why there are often concerns about snails and
other offspring being able to survive in the future. It takes
them about two years to be mature.Land snails engage in
various types of courting rituals to attract mates. They can last
for a couple of hours or half a day. They don’t make sounds to
call out to each other like many types of animals do. It may
surprise you to learn that snails don’t have the ability to hear.
So they use touching as a way of courting. They may cover
each other in slime that they produce from their bodies
before mating.

56. •Life cycle of
Jellyfish.

58. Information about life cycle of a
Jellyfish.
Most scyphozoan jellyfishes—including most of the large jellyfish with which many
people 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 sperm
which combine to produce a larva, called a 'planula' (plural = planulae). The planula
swims 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 or
underneath) of rocks, rotting logs, and decaying leaves that accumulate around the
lake's 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 attached
to the surface on which the planula settled, that produces a new free-swimming
medusa. The process by which new medusae are produced is called 'strobilation' and
involves metamorphosis of the end of a scyphistoma into an 'ephyra', an immature
medusa, that subsequently detaches and swims away. Depending on the species, a
single polyp may produce one or many ephyrae all at once, over a period of time, or at
different intervals. The ephyra subsequently develops into a mature medusa over a
period of weeks to months.

59. •Life cycle of a
housefly.

61. Information about life cycle of a
Housefly.
The housefly life cycle closely mirrors that of most
insects: a basic cycle that begins with an egg, then
develops through a larva phase, a pupa phase, and finally,
into an adult. During a warm summer -- optimal
conditions for a housefly -- the cycle, from fertilized egg
to adult, spans a mere seven to 10 days.After a male
housefly chases down and fertilizes a female counterpart,
she's ready to lay her eggs. Houseflies are solitary
creatures. Like the rest of the insect world, males and
females do not stick together after mating and, unlike
nesting insects, females do not care for or protect eggs.
Females simply leave the eggs where they will be safe
from predators and have plenty to eat upon hatching.

62. •Life cycle of a
Koala.

64. Information about life cycle of a Koala.
Koalas breed once a year and mate from August to January. At this time they
tend to move outside their normal territories looking for a mate. The male
has a deep, guttural call and the female a high pitched catlike voice. The male
has an oily gland on the centre of his chest which emits a strong odour. He
rubs his scent against tree trunks and limbs to mark his territory. When a
female is 2 years old she is ready to mate. Males are capable of reproducing
at 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 display
her readiness for the male. 35 days after mating the female gives birth to a
single Joey.Occasionally twins are reported but a single young is the most
common. At birth the Joey weighs less than 1 gram, has no fur, their eyes and
ears are closed and are the size of a peanut. On average koalas on mainland
Australia tend to produce one young every two years. After birth the furless
Joey makes its way, unaided, into the mother’s vertically opening pouch. It
attaches itself to one of the 2 teats and remains in the pouch for
approximately six months. During this time it develops slowly, and at about
22 weeks the eyes open and it begins to peep out of the pouch
