Orangutan

The orangutan, Pongo pygmeus, a great ape like gorilla, is native to the forest on the island of Borneo and Sumatra. Its name is Malayan and means, "man of the woods." Orangs have a shaggy coat of long, coarse, reddish brown hair. Adult males also have reddish blond beards and mustaches, well developed cheek pads, and a large throat pouch that is used as a sound resonator to reinforce calls. Males are markedly larger than females averaging about 75 kg (165 lb) in weight, females, averaging about 40 kg (90 lb). A large male in the wild may weigh 100 kg (220 lb) and stand about 1.4 m (4.5 ft) tall. The orang's arm to ankles when the animal stands erect.

Orangs often live in small group of two to four animals, but adult males may be solitary. Orangs are arboreal, seldom leaving the trees, where they feed primarily on fruit but also on leaves, bark, and birds eggs. They build simple sleeping nests, or platforms, on which they spend the night.

Full maturity is attained at 10 to 12 years of age, sexual maturity is reached at about 8 years. Gestation lasts about 9 months. Humans are the orangs only significant enemy, and unless hunting and destruction of their forest are curtailed, orangs will soon become extinct.

The Biggest Insect

A ranger former who was traveling in New Zealand found the largest insect in the world: a Weta. The span of wings reached 18 cm, while weight is 3 times the weight of mice.

The giant Weta is the biggest insect on the world, and this founding is more bigger that founded before. Motffet and his friend find out this giant insect by combing plants deliberately in order to look for the giant Weta. Mostly people afraid to this giant insect, but Moffet is lying on his hand and giving them a carrot for feed.

This biggest insect behavior look different like other normal insect, don't affraid to human being. This weta eat his carrot, this insect is like don’t care to the human existence, it enjoy the carrot given. After take a picture of this weta then Moffet lying this insect to the ground. Weta has been there for 180 years before dinosaurus exist, and was believed have extinct.

Turtle Eggs Speak Before Hatch

Australian species of river turtle (Emyduramacquarii) lay a set of eggs in the sand river. Eggs that laid lower have development more slowly than above. However, eggs in the second part turned out to be hatched together.

Ricky-John Spencer from University of Western Sydney in Australia intrigued by that fact. He suspects that the eggs are "talking" first before hatching.

To prove his hunch, he designed experiments. Spencer dividing the number of eggs into two parts. One part was incubated at higher temperatures, while other parts were incubated at lower temperatures. After a two-thirds of the development of eggs, both parts then put back together.

According to Spencer, the two parts of the egg might communicate chemically. "Eggs were actually breathing. They breathe in oxygen and release CO2," he said as quoted by New Scientist.

Spencer explained that the faster development of eggs of CO2 would spend more. The concentration of CO2 is the kind of "call" as well as a trigger to make another egg grow faster.

Spencer's research results published in the Proceedings of the Royal Society B latest edition of November 2011. Spencer explained that hatched together is very important for the survival of sea turtles. This will ensure that vulnerable individuals are protected from predators. They have friends who protect.
