Orangutan, Protected by Law

Orangutans are the most intelligent primates and use a variety of sophisticated tools, also making sleeping nests each night from branches and foliage. They are more solitary than other apes; males and females generally come together only to mate. Orangutans may live for up to 50 years in the wild. Unlike gorillas and chimpanzees, orangutans are not true knuckle-walkers, and are instead fist-walkers. Like the other great apes, orangutans are among the most intelligent primates Orangutans do not swim. Fruit makes up 65–90 percent of the orangutan' food,

The most recent estimate for the Sumatran Orangutan is around 7,300 individuals in the wild. Orangutan habitat destruction due to logging, mining and forest fires, as well as fragmentation by roads, has been increasing rapidly in the last decade.

Elephants, Symbol of Wisdom

Elephants are the largest land animals now living. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kilograms. They typically live for 50 to 70 years. The largest elephant ever recorded was shot in Angola in 1956. This male weighed about 11,000 kg.

Elephants are a symbol of wisdom in Asian cultures and are famed for their memory and intelligence

The Sumatran Elephant is found only on Sumatra. Population estimates for this group range from 2,100 to 3,000 individuals. It is very light grey in colour and has less depigmentation than the other Asians, with pink spots only on the ears. Mature Sumatrans will usually only measure 1.7–2.6 m at the shoulder and weigh less than 3,000 kg

One thing that interesting from elephants are their trunk which is used for drinking. Elephants suck water up into the trunk up to 14 litres at a time and then blow it into their mouth. Elephants also suck up water to spray on their body during bathing. Beside that, familiar elephants will greet each other by entwining their trunks, much like a handshake.

Tiger, Pooh's Friend in Winnie The Pooh

The Sumatran Tiger itself is found only on the Indonesian island of Sumatra, and is critically endangered. It is the smallest of all living tiger subspecies, with adult males weighing between 100–140 kg and females 75–110 kg. Their small size is an adaptation to the thick, dense forests of the island of Sumatra where they reside, as well as the smaller-sized prey. They have a lifespan of 10-15 years in the wild, but can live longer than 20 years in captivity. The wild population is estimated at between 400 and 500, seen chiefly in the island's national parks. Recent genetic testing has revealed the presence of unique genetic markers, indicating that it may develop into a separate species. This has led to suggestions that Sumatran tigers should have greater priority for conservation than any other subspecies. While habitat destruction is the main threat to existing tiger population (logging continues even in the supposedly protected national parks), 66 tigers were recorded as being shot and killed between 1998 and 2000, or nearly 20% of the total population.
