ANIMALS OF THE DESERT

Animals of the deserts have developed special bodies and ways of life that enable them to survive in

extreme heat.

Many desert dwellers have light coloured skin which helps to keep them cool by reflecting sunlight.

These animals include desert foxes, jack rabbits, and various kinds of snakes.

Desert foxes have long ears. When overheated, these animals move to a cool cave or burrow where they can

get rid of excess body heat through their ears.

Centipedes, kangaroo rats, rattle snakes and scorpions spend the day in burrows, they come out to search

for food when temperatures drop at night.

Some snails, lizards, and ground squirrels aestivate or sleep through the summer.

Somme animals have developed more unusual ways to cope with the desert climate; for example the cape

ground squirrel makes its own shade using its bushy tail like a parasol.

Fairy shrimps and spotted toads spend months or years underground waiting for rain to create ponds they

may then quickly feed and reproduce before the ponds dry again.

All animals of the desert must drink water which is often in short supply. They obtain water from plants,

small ponds and from the animals they eat.

DESERTS

Life is a constant struggle for survival in desert areas which exist on every continent but Antarctica.

Most deserts receive less than five inches of rain annually.

In fact the Atacama Desert in Chile goes for years with no rain at all.

Some deserts like the Sahara of North Africa and the Mohave Desert of the United States are hot all the year

round.

Others, such as the Gobi desert in Asia are cold in winter.

To cope up with almost constant drought plants are small and have water conserving leaves and cacti inAmerican deserts store water in their stems.

To prevent overheating, desert snakes and lizards conserve water.

Activity 1: let us understand it.

Freshwater life

Most of the ponds, lakes and rivers on the continents contain fresh water which is less salty than ocean

water.

Plants and animals that are adapted to this low salt content would not survive in the ocean.

Pond and lake animals include a variety of fishes, as well as insects, frogs, turtles, ducks and birds.

Vegetation includes algae along with rooted and floating plants such as waters lilies and cattails.

In rivers however, vegetation is often swept away by swift flowing water, as a result, animals in rivers tend

to feed on insects, dead plants and animals that fall into the water from the banks.

River animals are also adapted to survive currents. Tadpoles for example, may use suckers to attach

themselves to the rocks and streamlined bodies make trout and salmon powerful swimmers.

LIFE IN THE OCEANS

From the smallest creatures in the world to the largest, animals are also and live in the vast oceans.

Some of the tiniest creatures called plankton are also among the most important to life in the ocean.

Plankton includes shrimp like creatures, known as krill and copepods. They commonly live in the open seaand provide food for many other sea animals, including many fish and even some whales.

The frigid waters of the polar seas contain such animals such as cod, halibut, seals and whales. Many animals

thrive in the coral reefs of warm tropical seas, including lobsters and many types of brightly coloured fish.

Various ocean animals can live in shallow water near the shore, in tidal pools and on rocks; they include

anemones, barnacles, mussels, octopuses and starfish.

The great depths of the ocean are completely dark and the water there are bitterly cold; even so, animals

such as anglerfish, clams and tube worms live in these harsh environments.


8/18

Animals such as flying fish, manta rays, marlins and porpoises, generally stay close to the ocean surface. Just

above these animals, albatrosses, gulls and petrels fly over the sea.

Many marine animals are at the mercy of human activity. The demand for seafood has led to overfishing of

halibut, herring, salmon and some other sea creatures. Millions of dolphins have drawn in fishing nets that

were intended to catch cod, tuna and other fish. In addition, spills of toxic material and other forms ofpollution have reduced the numbers of some ocean species.

Activity 1: Do you remember the animals mentioned in the video? Look at the power point animals names

and then, write the names of the following animals.

LIFE IN POLAR REGIONS

However the seas in the arctic and the Antarctic have large numbers of wild life including fish, giant sponges,

whales and tiny shrimplike creatures called krill.

Krill provide food for many other sea animals including numerous fish and some whales. Various animals live

on the coasts of polar seas, polar bears, sea lions and walruses spend much of their time on floating sheets o

ice in the arctic. Penguins and seals live on the Antarctic coast.

Many animals inhabit the vast arctic tundra, the cold treeless planes of northern Asia, North America and

Europe. They include caribous, ermines, musk oxen, reindeer, lemmings, snowy owls and wolves.


10/18

Shallow ponds in this region provide a place for mosquitoes and many other insects to lay their eggs. These

insects serve as food of birds that migrate to the tundra each summer to nest. Animals that live in Polar

Regions have developed bodies and ways of life that enable them to deal with the frigid polar weather.

Caribou, musk oxen and polar bears have thick fur which helps them stay warm. The arctic fox and arctic

hare have short ears and tails which keep them from losing too much body heat. Arctic ground squirrels

hibernate or sleep through the long polar winter they curl up on a burrow and their body temperature drops

saving energy during their sleep.

Activity 1.- Look at the power-point presentation, and then write the names of the following animals


11/18

Activity 2.- The first three animals have many things in common and sometimes are confused. Read the

following text and then do the exercise of the marine mammal center.

. Suborder Pinnipedia are "flipper-footed" marine mammals. Pinnipeds can safely come out on land to rest, breed,

and give birth, and are comprised of three families:

1. Family Otariidae:Sea lions and fur seals have visible external ears and can "walk" on all four flippers by rotating

their rear flippers forward. They are more mobile on land than true seals, and are often seen in circuses andaquariums. Their swimming power comes from their large front flippers. In California, this family includes California

sea lions, Steller sea lions, northern fur seals, and Guadalupe fur seals.

2. Family Phocidae:True seals have no external ears and crawl on land because their front flippers are small and

their hind flippers cannot rotate forward. Their swimming power comes from their large, almost fan-like rear

flippers. In California, this family includes harbor seals and northern elephant seals.

3. Family Odobenidae: Walruses are distinctive for their two long tusks. Walruses inhabit the Arctic seas and ice

floes. They have no external ears, but can rotate their hind flippers and "walk" on land. They are set apart from

other pinnipeds not only by their tusks, but also by the presence of two large air pouches, or sacs, extending from

each side the pharynx (in the neck). These pouches can be inflated to hold the head above water when sleeping, or

used as resonance chambers to enhance underwater sound.

THE TAIGA FOREST

Boreal forests encircle the earth across North America from Alaska to Labrador, and across Eurasia from

Sweden to northern China, Korea and Japan.

Boreal means northern. The boreal forest is also known by its Russian name taiga. Few people live in boreal

forest because of their harsh climate; short warm summers, hot in some places, and long severely coldwinters.

Only a few species of trees such as pine, fir and spruce can survive such a climate.

Some forest animals such as squirrels, chipmunks and bears cope with the icy winters by hibernating.

Moose, elk and reindeer must search for tender mosses and lichens by scraping through the snow. Wolves

and lynxes compete for the few small animals that continue to move.

Activity 1: Not always British English and American English use the same words. Here there is an example:

LIFE IN THE TEMPERATE FORESTS

Temperate forests have warm summers and cold winters. Most of these forests occur in Asia, Europe,

Australia and North America.

Many animals in temperate forests have small bodies that allow them to move easily through the

underbrush.

These include mammals such as chipmunks, mice, racoons, squirrels. Larger forests animals include bears,

deer and wild boar. In wet forests slugs and other snails are common; beavers, fish, frogs, muskrats, otters,

salamanders and turtles live in or on near woodland streams, ponds and lakes. Salamanders are often

plentiful they hide in the leaf litters and under rocks where they feed on insects and other small organisms.

A great number of birds also find their home in the temperate forests; they nest in the trees and trunks.

The destruction of temperate forests, threatens the survival of temperate forests animals. Many temperate

forests have been cleared for farms and cities while many others have been cut down for fuel and lumber.

Extensive lugging in the pacific northwest of United States for example, has destroyed much of the habitat of

the spotted owl threatening the continue of existence of this animal

Activity 1: look at the power point presentation and try to learn the names of the animals

TROPICAL RAINFOREST SLIDE SHOW

Large tropical rainforest grow around the world in lands near the equator, in central and South America,

Africa, southern Asia, Australia and some islands of the pacific.

The rain forests flourish in warm areas that have year-round rainfall as much as 80 to 160 inches of rain a

year.

Each acre of rainforest has more vegetation than an acre on anywhere else on earth.

Tall trees create a leafy green canopy above. Smaller trees, shrubs and ferns fill on the spaces bellow.

Dangling wines encircle the trees and shrubs.

Millions of species of insects thrive in the rainforest. Slots, monkeys, parrots and snakes live in the trees. A

few large mammals hunt on the forest floor below.

The ant eater in central and south America, the hippopotamus in Africa and the tiger in southern Asia

People count in the rainforest to provide timber.

Coral Reef Ecosystem

Coral reefs are usually found in tropical waters near the surface because the coral needs energy from the

sun to survive.

The plants and algae there, convert light energy into chemical energy through photosynthesis.

As fish and other creatures eat the algae and each other, energy is passed on through the food chain.

The reef could not exist without coral. Each small circle of coral or polyp is made up of many coral organisms.

The brown spots here are plant cells; they live inside the coral organisms. The plant cells collect energy from

the sun through photosynthesis. This provides oxygen and sugar for the coral organisms to feed on.

As the organisms grow, the polyp forms a compartment of calcium carbonate mineral. The polyps each live

in their individual compartments like neighbours in an apartment building.

Each polyp has a mouth surrounded by stinging tentacles.

During the day the corals algae cells photosynthesise, but at night the polyps extend their tentacles to feed

on plankton, tiny organisms that drift in the water.

Meet another creature that feeds on plankton, the spiny leny watches for plankton that may drift close

enough to be snatched and eaten.

When this parrot fish takes a large bite of coral rock, it is actually to feed on the polyps. The fish is able to

extract the living coral by chewing it up with its extra set of internal jaws. Parrot fish creates much of the

sand at bottom of the reef.

The sea cucumber eats the sand and collects algae and organic debris from it. Creatures like the sea

cucumber make sure that the reefs floor stays clean.

The ruffle sea slug like the coral organism, has a double diet, it both eats plants and get energy from the sun.

The ruffles on its back act as a solar collector. Theyre filled with chloroplasts; the organelles that also carry

out the photosynthesis in plant cells.

The slug spends less time looking for food because it can get energy from the sun in the daytime.

Were not for the plant eaters or herbivores, the reef might be overgrown with algae.

The long spine sea urchin helps keep the algae in check. By day, it stays close to the coral. Its mouth is

conveniently located on its underside for easy grazing.

The urchin is well protected, but less fortunate herbivores must watch out for flesh eating or carnivorous

predators.

The great barracuda cruises overhead, hunting at dawn and at dusk.

The moray eel is generally nocturnal and spend its days lurking in caves. It comes out at night to feed onsmall fish.


18/18

The yellow-tail snapper may not look like much, but it is a mighty hunter. Of all the predators in the reef it is

the most abundant.

One day, this predator too may become prey or it may die at old age and make a meal for scavenger.

In the coral reef, as in all ecosystems, energy will have flowed from the sun to the plants, to herbivores, tocarnivores, to scavengers and decomposers.
