Picture from www.bbc.co.uk  Sumatran tigers are especially well represented in zoos around the world, most of which participate in sophisticated global conservation breeding programs. More than 270 Sumatran tigers are now documented in formal studbooks and are involved in captive breeding programs aimed at preserving their genetic uniqueness. This captive population is occasionally supplemented by... 

  Picture From www.lablink.or.id Wild Sumatran tigers have survived within the isolated and somewhat continuous political environment of the Island of Sumatra. This has afforded researchers, such as The Sumatran Tiger Project team, an opportunity to study these animals’ genetic status in their natural habitat over an extended period of time. As a result, important first-hand field data has been... 

Picture from www.worldwildlife.org   The Sumatran tiger (Panthera tigris sumatrae) is the smallest of the remaining five tiger subspecies. It has lived exclusively, for over a million years, in the once extensive moist tropical jungles of the island of Sumatra, Indonesia. The Sumatran tiger is only found in Sumatra, a large island in western Indonesia. It lives anywhere from lowland forests to... 

Sperm Whale (Physeter Catodon) This large whale weighs an average of 40 tonnes, and can reach weights of 50 tonnes. Large males can grow to 20 metres in length, and females only 12 metres. The females weigh on average one third of what the male whale weighs. They have a large box type head, which makes it easily distinguishable and sets the sperm whale aside from other whales. These whales can swim... 

Long-Beaked Echidna (Zaglossus Bruijni) The echidnas and the duck-billed platypus differ from all other mammals in that they lay shell-covered eggs that are incubated and hatched outside of the body of the mother. A female long-beaked echidna usually lays 1 egg into its pouch. The eggs of the long-beaked echidna are soft-shelled and hatch after 10 days, whereupon the young remain in a pouch, dependent... 

Humpback Whale (Megaptera Novaeangliae) This large whale weighs an average of 30 tonnes, ranging in length from 12 to 16 metres. The female Humpback Whale is normally one or two metres longer than the male Humpback Whale. They have two blowholes. They range in colour from almost white through to gray and black. The word “Megaptera” translates to “huge wings” referring to the... 

Sei Whale (Balaenoptera Borealis) The Sei Whale. The Sei Whale is found in waters all over the world, although it avoids tropical or polar regions. They are found in the Indian Ocean, Atlantic Ocean and Pacific Ocean. They range in size from around 12 to 15 metres. The largest specimen ever reported was 20 metres in length. They weigh an average of 23 tonnes but weights of 27 tonnes have been reported.... 

Fin Whale (Balaenoptera Physalus) The Fin Whale is found in oceans all over the world, from the tropics to the polar areas. They are known as a pelagic species, often occuring in shallow waters close to the shore. Even though they are found in oceans across the world, they are not as common in tropical waters or ice laden seas. They are around 19 to 20 metres in length, and can weigh as much as an... 

White-Handed Gibbon (Hylobates Lar) The White-Handed Gibbon (Hylobates lar) is an endangered, tree-living primate. Because of hunting and clearing of the rainforests where they make their home, these animals are in danger of extinction. It is estimated that a mere 10% of their natural habitat remains, and most of this falls in protected sanctuaries. The young are often captured and sold as pets. White-Handed... 

Blue Whale (Balaenoptera Musculus) The Blue Whale The blue whale (Balaenoptera musculus) is the largest mammal found on the planet, perhaps the largest mammal that has ever lived, thought to be even larger than even the largest of the dinosaurs. It belongs to a family of animals known as the rorquals and is termed a baleen whale. Unfortunately, it is currently listed as endangered and was hunted nearly...
