What is cold-blooded animals? What is warm-blooded animals?

3. Cold-blooded animals
• Cold-blooded animals, like reptiles, amphibians, and fish, become
hotter and colder, depending on the temperature outside.
• For example, when the sun sets at night, their bodies are cooler
because it is less warm outside. When the sun is out, however, their
bodies soak up the heat and become warmer.
• Cold-blooded animals are much more active in warm environments
and are very sluggish in cold environments. This is because their
muscle activity depends on chemical reactions which run quickly
when it is hot and slowly when it is cold.
• A cold-blooded animal can convert much more of its food into body
mass compared with a warm-blooded animal.

4. How do cold-blooded animals maintain their
body temperature?
• Cold-blooded animals often like to bask in the sun to warm up and increase
their metabolism. They will also expand their rib cage to increase their
surface area and will darken their skin to absorb more heat.
• When a reptile is too hot, it will lie parallel to the sun's rays, go into a shady
area, open its mouth wide, lighten its skin color or burrow into cool soil.
• Fish who live in areas where the winters are cold move to deeper waters
during the colder months or migrate to warmer waters.
• Snakes, lizards, toads, frogs, salamanders and most turtles will hibernate
during cool winters.
• Some insects die when it gets too cold, however others survive by
migrating to warmer areas or moving underground.

5. The advantages
• Cold-blooded animals require much less energy to survive than warm-
blooded animals do. Mammals and birds require much more food
and energy than do cold-blooded animals of the same weight.
• The ratio of a body's surface area to its mass is less the larger the
animal is. This means that larger warm-blooded animals can generate
more heat than they loose and more easily keep their body
temperatures stable

6. The disadvantages
• A cold-blooded animal's level of activity depends upon the
temperature of its surroundings.
• A reptile, for example, will increase its body temperature before
hunting and is better able to escape predators when it is warm.
• Cold-blooded animals also need to be warm and active to find a mate
and reproduce.

7. Warm-blooded animals
• Warm-blooded animals keep the inside of their bodies at a constant
temperature.
• They generate their own heat when they are in a cooler environment,
and by cooling themselves when they are in a hotter environment.
• It generates heat by burning the food you eat. Thus, they have to eat
a lot of food.
• Only a small amount of the food that a warm-blooded animal eats is
converted into body mass.
• The rest is used to fuel a constant body temperature.

8. How do warm-blooded animals maintain their
body temperature?
• When overheated, mammals sweat or pant to allow evaporation to
take away excess heat.
• Some mammals have body parts designed to prevent overheating.
For example, elephants have huge ears that radiate heat, keeping the
elephant comfortable in scorching temperatures.
• They also reduce their temperature by entering water or finding
shade.
• In extreme cold, warm-blooded animals shiver to generate heat
• Furred mammals have thick, insulating winter coats but shed them to
avoid overheating in the spring and summer.
• Birds get rid of excess body heat by breathing it out.

9. The advantages
• Warm-blooded animals can live in almost any surface environment on
Earth, like in arctic regions or on high mountains.
• Easy to survive everywhere
• They can make their own body heat even when it is cold outside
• Warm-blooded animals can remain active, seek food, and defend
themselves in a wide range of outdoor temperatures.

10. The disadvantages
• Warm-blooded animals’ body provides a nice warm environment for
viruses, bacteria and parasites to live in.
• Mammals and birds tend to have more problems with these
infections.
• Heat is a very serious problem for small warm-blooded animals

11. BOA
• The boa constrictor also called
red-tailed boa, is a species of
large, heavy-bodied snake.
• Boas are nonvenomous
constrictors found in tropical
Central and South America.
• Like their anaconda cousins,
they are excellent swimmers,
but prefer to stay on dry land,
living primarily in hollow logs
and abandoned mammal
burrows. Did you know?
Some South Americans keep boas in their houses to control rat
infestations.

12. IGUANA
• Iguanas are lizards identified by
their stocky stature, the saggy
skin on their throats and the
spines that protrude from their
heads, necks, backs and tails.
• The outside temperature is what
keeps them warm since they
have no way to regulate internal
heat with their own bodies.
• These lizards are found in
Mexico, Central and South
America, the Galápagos Islands,
on some of the Caribbean
islands, Fiji and Madagascar.

13. RED-EARED
SLIDERS• They are almost entirely aquatic,
but as they are cold-blooded,
they leave the water to sunbathe
to regulate their temperature.
• Red-eared sliders get their name
from the small red stripe around
their ears.. The "slider" in their name
comes from their ability to slide off
rocks and logs and into the water
quickly.
It is the most popular
pet turtle in the United
States and is also
popular as a pet in the
rest of the world.

14. TURTLES • Turtles are classified as amniotes,
along with other reptiles, birds,
and mammals. Like other
amniotes, turtles breathe air and
do not lay eggs underwater,
although many species live in or
around water.
• Their internal temperature varies
according to the ambient
environment.

15. ANTS• Ants typically live in structured
nest communities that may be
located underground, in ground-
level mounds, or in trees.
• Ants can lift and carry more than
three times their own weight.

16. BEE
• All honeybees are social and
cooperative insects.
• The queen's job is simple—
laying the eggs that will spawn
the hive's next generation of
bees. There is usually only a
single queen in a hive. If the
queen dies, workers will create a
new queen.

18. BUTTERFLY• Butterflies have the typical four-
stage insect life cycle.
- Winged adults lay eggs on the food
plant on which their larvae, known
as caterpillars, will feed.
- The caterpillars grow, sometimes
very rapidly, and when fully
developed, pupate in a chrysalis.
- When metamorphosis is complete,
the pupal skin splits, the adult
insect climbs out, and after its
wings have expanded and dried, it
flies off.

19. BEETLE
• Beetles are a group
of insects that form the order
Coleoptera, in the
superorder Endopterygota.
• Their front pair of wings is
hardened into wing-
cases, elytra, distinguishing
them from most other insects.
• Beetles play many roles in
human culture, from the sacred
scarabs of ancient
Egypt to beetlewing art and use
as pets or fighting insects for
entertainment and gambling.

20. SALMON
• Salmon is considered to be
healthy due to the fish's
high protein, high omega-3 fatty
acids, and high vitamin
D content.
• Salmon is also a source of
cholesterol, with a range of 23–
214 mg/100 g depending on the
species.
• They are born in fresh water,
migrate to the ocean, then
return to fresh water
to reproduce.
Salmon is a popular
food.

21. SHARKS
• Sharks have adapted to living in
a wide range of aquatic habitats
at various temperatures.
• Most sharks are especially active
in the evening and night when
they hunt.
• Some sharks migrate over great
distances to feed and breed.
• Sharks mature slowly, and reach
reproductive age anywhere from
12 to 15 years.
• This, combined with the fact
that many species only give birth
to one or two pups at a time,
means that sharks have great
difficulty recovering after their
populations have declined.

22. GOLDFISH
• The goldfish is one of the
smallest fish.
• Despite it being available
throughout the year and day, it
is actually quite rare.
• It can be found in the river. It has
a tiny shadow and is 15
centimeters long.
• It was one of the earliest fish to
be domesticated, and is one of
the most commonly
kept aquarium fish.

23. SWORDFISH
• The Swordfish offers a very
interesting body.
• They have the long bill that looks
similar to a sword and that is
where their name derives from.
• They are very predatory fish and
they are also a class that many
sport fishermen love to be able
to capture.
• The long bill is very sharp and it
helps them to remain left alone
from other forms of aquatic life.
• When they are threatened
though they can use it to help
them to have some type of
defense against the predator.

24. BEARS
• Some species of Asiatic bear build
nests in the trees. They can use
these for hiding, eating and even
sleeping.
• Bears have great senses of smell,
sight and hearing. A bear can smell
food, cubs, a mate or danger from
miles away.
• They also rely on other bears'
sense of smell when they mark
their territory with urine and
droppings.
• Bears have two layers of fur. A
short layer of fur keeps the bear
warm. And a long layer keeps
water away from the skin and short
fur.
• The shape of a bear’s claw differs
according to the type of bear.
Bears can run up to 40 miles per hour, fast enough
to catch a running horse.

25. LIONS• Lions are the only big cats to live in
groups, called prides. They work
together to defend territory and hunt.
• The females in the pride tend to do
the majority of the hunting. They
work as a group and use intelligent
hunting tactics to catch prey.
• Lions enjoy relaxing and lazing
around. They spend between 16 and
20 hours each day resting and
sleeping.
• They have few sweat glands so they
wisely tend to conserve their energy
by resting during the day and become
more active at night when it is cooler.
• Lions have terrific night vision. They
are 6 times more sensitive to light
than humans. This gives them a
distinct advantage over some prey
species when hunting at night.
• Lions communicate through a range of
behaviours and their expressive
movements are very highly
developed.

26. MOUSE
• The mouse is a small rodent that is
spread widely throughout nearly
every country.
• There are nearly 40 different
known species of mouse found
throughout the world. The
different mouse species range
in size and colour.
• Mice are usually nocturnal animals.
They have poor eyesight but make
up for this with their very good
hearing and smell.
• The mouse is often
easy prey around the world. Due to
this the mouse generally does not
live for much longer than a few
months in the wild
Mice tails can grow as long as their bodies.

27. DOGS
• A dog’s sense of smell is 10,000
better than human. They can
even use this super sense to
detect diseases such as cancers
and diabetes.
• Dogs only have sweat glands in
their paws. This helps to wet the
bottom of their feet on a hot
day, and it’s also why dogs rely
on panting as a means of cooling
down.
• Dog’s nose print is as unique in
identifying them as our
fingerprint is to us.
• Dogs are capable of locating the
source of a sound by using their
swiveling ears like radar dishes.

28. DUCK
• Ducks are omnivores. They feed on
aquatic plants, small fish, insects,
worms, grubs and more.
• Ducks can live from 2-12 years,
depending on species
• Ducks have water-proof feathers.
There is a special gland that
produces oil near the duck's tail
which spreads and covers the outer
coat of the duck's feathers, making
it water-proof. Beneath the water-
proof coat are fluffy and soft
feathers to keep the duck warm.
• Some species of ducks migrate or
travel long distances every year to
breed.
• Ducks are found everywhere in the
world except the Antarctica which
is too cold for them.
• Ducklings are able to fly within 5-8
weeks.
• The production of eggs are affected
by daylight. When there is more
daylight, the ducks will lay more
eggs.

29. CHICKEN
• Chickens form complex social
groups and communicate using
over 30 types of calls.
• The male is called a rooster. The
female is called a hen while the
young are called chicks.
• The male has a larger comb
compared to the female. The live
span of a chicken is about 10 to
15 years.
• The male is larger and more
brightly colored than the female.
• Roosters perform a little dance
called ‘tidbitting’ in which they
make sounds (food calls) and
move their head up and down,
picking up and dropping a bit of
food.

30. OSTRICH• Even though it has wings, it can't fly,
but it help a lot to balance when the
ostrich is running at full speed and
needs to change directions.
• The ostrich is famous for its speed on
the ground. Its powerful legs enable it
to reach speeds of 40 miles per hour.
• Ostriches have three stomachs.
• Ostriches sometimes eat stones and
pebbles which help them to digest
their food.
• Ostriches don’t really bury their heads
in the sand. They do lie on the ground
and stretch their necks out to hide
when trouble appears.
• The ostrich has the largest eye of any
land animal, measuring almost 5 cm
allowing predators such as lions to be
seen at long distances.
The ostrich is the largest bird in the world

31. SEAGULLS
• Seagulls are omnivores.
• Seagulls can drink both fresh and
salt water because they have a
special pair of glands right above
their eyes to flush the salt.
• A small claw halfway up their lower
leg enables them to sit and roost
on high ledges without being
blown off.
• They eat fish, squid, shellfish and
mussels. They also eat bugs and
earthworms.
• Seagulls make nests simply by
hollowing out a soft spot in the
sand. They try to choose an area
near grass, rocks or logs for
protection.

32. WHALES• The tongue alone of a blue whale
can weigh as much as an elephant.
• Whales breathe air as we do.
• Therefore, they need to reach the
surface of the ocean to breathe.
• When they reach the surface, they
take air in through this blowhole.
• Whales can swim as fast as 30
miles per hour.
• Some Whales can stay underwater
for as long as 90 minutes.
• They travel alone or in groups, or
pods, on their annual migrations.
• There are two types of whales.
• Baleen whales have a comb-like
fringe, called a baleen, on the
upper jaw. They are the largest
species of whale.
• Toothed whales have teeth. They
sense their surrounding
environment through echolocation.
The blue whale is the largest animal on Earth.

33. KANGAROO
• Kangaroos are large marsupials
found only in Australia.
• Kangaroos are the only animals
that hop. Their springy hind legs
and feet are much stronger and
larger than their arms.
• Kangaroos are grazing herbivores.
Their diet consists mainly of
grasses. They can survive long
periods without water.
• Kangaroos live in varied habitats,
from forests and woodland areas
to grassy plains and savannas.
• Kangaroos are social and live in
groups called a mob, a herd or a
troop. If a kangaroo suspects there
is danger in the area, it will stomp
its foot on the ground to alert
others.
• A female kangaroo is pregnant for
21 to 38 days, give birth to up to
four offspring at one time.
• At birth, the baby can be as small
as a grain of rice, or as big as a bee.

34. PANDA
• Giant pandas live in bamboo
forests in remote mountainous
regions of western China.
• Giant pandas have broad paws
with furry undersides and long
retractile claws that help them grip
when climbing trees.
• Giant pandas are omnivores, which
means their diet consists of both
vegetation and meat. However,
bamboo is by far their favourite
food.
• Baby pandas are born pink and
measure about 15cm.
• They are also born blind and only
open their eyes six to eight weeks
after birth.
• They do no hibernate during winter
months, but instead may migrate
short distances.
• They are shy animals that prefer to
live alone.

35. GIRAFFE
• Giraffe is the tallest mammal in the
world.
• Giraffes spend most of their lives
standing up. They even sleep and
give birth standing up.
• Giraffes are sociable, peaceful
animals which rarely fight.
• No two giraffes have the same spot
pattern.
• Giraffe tongues are huge to allow
giraffes to forage on trees.
• When giraffes walk, they move
both legs on one side of their body
and then both legs on the other
side.
• These long legs allow giraffes to
run as fast as 35 miles an hour over
short distances and cruise
comfortably at 10 miles an hour
over longer distances.
• A swift kick from one of their long
legs can do serious damage to—or
even kill—an unlucky lion.
