There are ten species of bears. They are largely adapted to
omnivorous diet, subsisting on wild berries and nuts as well as insects,
roots, small birds and rodents. Bears have well developed molars and
very acute sense of smell. On the contrary they have weak eyesight and
hearing capacity. The Polar bear is unique amongst the bears in being
the largest species.
The Leopards are the most adaptable of all the higher mammals. They
are mostly found in Asia and Africa. In spite of being banned under
CITES, trade in leopard skin flourishes in many parts of south east
Asia.
Penguins are the most highly specialized of all birds for marine
life. They perform their swimming action solely by their flipper like
wings, while their webbed feet are used as rudders.
Penguins are highly gregarious and a population density of half a
million birds in 500 acres has been counted at a colony unison in
Antarctica.
We share 1.4% of our DNA with the Chimpanzees. Fifty years ago, there
were probably a million living Chimpanzees in Africa but today, as few
as 150,000 are left in the wild.
Eagles are one of the most prominent birds amongst the raptors (birds
of prey). They are capable enough to hunt even the living animals.
When you think of the porcupine you probably picture its quills
pointing from their back. These quills are a good defense against many
predators who do not like getting a mouthful of quills. They are
extremely good swimmers.
Dall sheep are the only white wild sheep. They spend most of the year
up in the mountains in rocky areas with cliffs. The cliffs give them
protection from predators. The predators can not go all the places the
Dall sheep can. The horns on a Dall sheep, both the male and female grow
horns, are made of keratin, the same material as our hair and
fingernails.
Arctic Terns are very sleek looking birds. They have long, pointed
wings, a forked tail, a black cap and red beak and feet. When hunting
the terns can hover over an area looking for prey. Arctic terns are the
furthest migrating birds; they fly from Alaska to Antarctica every year
for the Alaskan winter.
Beluga whales are white. Each summer they shed their skin. They
remove the old skin by rubbing it on gravel or coarse sand bottoms of
rivers. Before they shed, their skin is yellow and scared. After they
shed their skin is shiny and white. The beluga can swim forward,
backwards and upside down.
