“Dad, is it really so that mass depends on energy?”, C. Adler, an American physicist was asked by his son.

“No! Or rather - yes. Actually it doesn’t, but don't tell your teacher about it”, C. Adler answered.

The next day the physicist’s son stopped studying physics.

Fresh Water Fish: Giant Pangasius

Assalamualaikum..





Fresh Water Fish: Giant Pangasius

1st.. Thanks to someone coz went to Zoo Negara with me.. This is one of the biggest fresh water fish in the world, it called Giant Pangasius. This species can be found in Chao Pyraya and Mekong Basin in Indochina.

It has declined drastically mainly due to over fishing and it is now considered Critically Endangered. It has a wide, flat, whiskerless head. It has a silver, curved underside and a dark brown back. Its dorsal, pectoral and pelvic fins are dark gray and the first soft ray is extended into a filament. Full-grown adults can reach 3 meters (120 in)  in length and weigh up to 300 kg (660 lb).

Interesting Places In Borneo - Part 2

           
Danum Valley


           Danum Valley Conservation Area is a 438 square kilometres tract of relatively undisturbed lowland dipterocarp forest in Sabah,Malaysia. The area holds unique status in the sense that before it became a conservation area there were no human settlements within the area, meaning that hunting, logging and other human interference was non existent making the area almost unique.










A two-hour car journey from the nearest town of Lahad Datu, the rainforest here has an isolated and pristine beauty all of its own. From the viewpoints along the treetop canopy, dense jungle foliage and dramatic mountains stretch for miles on every side and it is easy to forget the hustle and bustle of everyday life.

Wildlife of the Danum Valley

A nature lover’s paradise, the area is known for its huge variety of birds and other wildlife. It is possible to spot wild cats, orang-utans, macaques, gibbons, red leaf monkeys, pygmy elephants and - if you are very lucky - the rare clouded leopard. The canopy walkway is a great way to experience life in the treetops where much of the wildlife is to be found.
A number of jungle trails are available, including the trek to the viewpoint which passes Coffin Cliff, an ancient Kadazan Dusun burial site.

Interesting Places In Borneo - Part 1

Mulu National Park, Borneo

            Under the national park’s blanket of jungle can be found the world’s largest limestone cave system, dominated by the towering Gunung Mulu. The area is so isolated that it is accessible only by light aircraft and, once in the park, exploration is on foot or by boat.







Cave systems

A highlight is to follow the labyrinthine passages of Clearwater Cave, perhaps swimming in its pellucid waters, or to visit Lang Cave or Deer Cave at dusk to witness the bats emerging in their shadowy hordes.

Wildlife of Mulu National Park

The park has been estimated to be at least five million years old and, with its soaring peaks and dense forest, it seems to defy time. The forest itself may seem peaceful, but the silence is often broken by the sounds of the gibbons, cicada, hornbills, bats and frogs, while in the steamy heat you can almost hear the creaking, as 8,000 species of plants and trees edge their way to a distant sky.
