Platypus
Many
people call platypus duckbill because this animal has a bill like duckbill.
Platypus is a native Tasmania and southern and eastern Australia.
Platypus
has a flat tail and webbed feet. Its body length is 30 to 45cm and covered with
a thick, and woolly layer of fur. Its bill is detecting prey and stirring up
mud. Platypus' eyes and head are small. It has no ears but has ability to sense
sound and light.
Platypus
lives in streams, rivers, and lakes. Female platypus usually dig burrows in the
streams or river banks. The burrows are blocked with soil to protect it from
intruders and flooding. In the other hand, male platypus does not need any
burrow to stay.
The Red Bird Of Paradise
An Indonesian endemic, the Red Bird of
Paradise is distributed to lowland rainforests of Waigeo and Batanta islands of
West Papua. This species shares its home with another bird of paradise, the
Wilson's Bird of Paradise. Hybridisation between these two species are expected
but not recorded yet.
The Red Bird of Paradise, Paradisaea
rubra is a large, up to 33cm long, brown and yellow bird of paradise with a
dark brown iris, grey legs and yellow bill. The male has an emerald green face,
a pair of elongated black corkscrew-shaped tail wires, dark green feather
pompoms above each eye and a train of glossy crimson red plumes with whitish
tips at either side of the breast.
The male measures up to 72 cm long,
including the ornamental red plumes that require at least six years to fully
attain. The female resembles the male but is smaller in size, with a dark brown
face and has no ornamental red plumes. The diet consists mainly of fruits,
berries and arthropods.
"What
is a Tornado?"
Tornadoes are known as one of the most
damaging disasters. What is the description of tornadoes? A tornado is a very
powerful column of winds which spirals around a center of low atmospheric
pressure. A tornado will look like a large black funnel which hangs down from a
storm cloud.
The name "tornado" derives
from the Latin "tonare". It means "to thunder." While the
Spanish developed the word into "tornear" which means "to turn
or twist". This is why a tornado is sometimes called twister or cyclone.
The
winds inside a twister can spin around at speeds up to 500 miles an hour, but
it usually travels at roughly 300 miles an hour. This speed twisting makes a
tornado the most dangerous storm.
The average tornado has a diameter of
about 200 to 300 yards. The smaller tornadoes are known as satellite tornadoes.
These small offspring, about 50 yards across, can be very fierce and do lots of
damage.
The forming of a tornado can be very
quick. Sometimes it can form in a minute or less. A tornado can travel across
the ground at high speeds, then it can suddenly vanish. Most tornadoes last
less than twenty minutes and travel less than 15 miles. However, the super
storms sometimes travel over 100 miles before they are exhausted.
