ANTS
Ants
belong to insect. They are small animals. They are usually black, but there are
some red ones. The body consist of three parts :
the head, the thorax, and the abdomen. Ants have several nerve centers, are the
largest being the brains, situated in the insect’s head. Most of these
creatures have a compound eye on each side of the head. These eyes may consist
of six to over a thousand lenses. Additionally, certain winged ants possess
three simple eyes on the back of the head though ant vision is often very dim.
The ant’s three pairs of legs are
attached to the thorax. So are wings, if the insect happens to have any. Next,
the abdomen, containing the crop, in which food
is stored and carried to others of the ant community. The ant’s stomatch and
intestines are situated behind the crop on its abdomen. One more thing, some
ants have a pain-producing sting. In fact, by stinging, fire ants have been
known to kill young birds that have not yet left the nest.
KOALA
The
koala is a marsupial mammal which means it has a pouch and suckles its young.
Koala is considered arboreal (tree dweling) mammals however they do descend to
the ground to move from one tree to the other.
Koala
has grey fur and large rounded ears on top of a big head. They are usually
approximately 60 – 85 cm tall with a stout body and short legs used for
climbing. Their size, coloring, and shape vary depending on Geographic range.
Males can weigh between 6 – 10 kilograms compared to females who are slightly
smaller and range between 5 – 7 kilograms.
Being
mostly nocturnal, a koala will spend most of its time sleeping in branches
throughout the day and feed mostly at dusk (they sleep for around 18 hours each
day).
Koalas
are specialist leaf eaters, feeding predominantly on eucalypt leaves. According
to the original word, koala means “no drink”, koalas will drink in time of
drought, extreme heat, and if they are sick. They will also feed on other
closely related species such as Lophostemon (swamp box) and corymba (blood woods).
SEA HORSE
Many
people imagine the sea-horse to be real horse living in the sea. This is not
true at all. The sea-horse is so called because it is a timy creature with a
horse – liked head which lives in the sea.
Sea-horse
are found mostly in warm sea. They have a long flexible tail which used for
wrapping around weeds for support. They swim in upright position, their
movements being helped by a rapidly oscillating fin in their back. The male
sea-horse lays her eggs in this pouch.
The
most remarkable thing about the sea-horse is that part of the process of
reproductionis taken over by the male creature. One the female sea-horse has
laid her eggs in the male creature’s pouch, she leaves. The hatching of the egg
is done by the male fish.
Malting
begins with the male and female sea-horse doing courtship dance. The male and
female creatures swim around each other in circles. At the end of the dance,
the male appears to bow to its partner, but in actually, the male is bending to
pump water from his pouch. Next, the female fish lays eggs into the male’s
pouch. About two hundred eggs are laid. The pouch, then close up. The female
sea-horse now swim away, leaving the male sea-horse to do hatching.
The
eggs are hatched about a month later. The young sea-horse are ejected from the
male creature’s pouch by means of muscular contractions.
THE TASMANIA DEVIL
The
Tasmanian devil is a marsupial – an animal that feeds and carries its young in
a pouch. It lives only in Tasmania and was called a devil by the early European
settlers because of its fierce appearance and loud screeching.
The
devil is the same size as a small doq. 1it has a large head, a stocky body, and
a short thick tail. While the fur is mostly black, there are often white
marking on the back and chest. Because the devil is a nocturnal animal (it is
active at night), it spends the days in the dense bush and hunts for food after
dark.
While
it can catch prey the size of a small wallaby the devil often feeds on the
bodies of dead sheep and cows from farms. Its very powerful –jaws and teeth
enable it to eat bones as well as the meat.
Devils
breedvin March and the young are born in April. While more are born, only two
or three babies survive to live in their mother’s pouch for four month. They
move with their mother into a whole or a hollow log until they are ready to
live on their own in the bush at the end of December. Devils live until they are
seven or eight years old.
