White Sturgeon
Tucked away from the powerful embrace of the current, white-tip reef sharks huddle in the cradle of a coral bastion. Their collective stillness offers a striking contrast to the dynamic flow just beyond their refuge, a natural haven within the rhythm of the reef.

The dugong is a medium-sized marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century. The dugong is the only strictly marine herbivorous mammal, as all species of manatee use fresh water to some degree.

Adults of Humphead or Napoleon Wrasse Cheilinus undulatus develop thick lips and a prominent bulbous hump on the forehead and can grow up to more than 2.2 meters. The species inhabits steep outer reef slopes, channel slopes and lagoon reefs. Primary food are mollusks, fishes, sea urchins, crustaceans and other invertebrates. Napoleon Wrasse is one of the few predators of toxic animals such as sea hares, boxfishes and crown-of-thorns starfish. Napoleon Wrasse is is seriously endangered, being hunted to the brink of extinction to feed a growing demand among wealthy Chinese diners for luxury live fish. Not wise, so crown-of-thorns starfishes take over and destroy the reefs.
Unique ancient lungfish, surviving from the Jurassic period. Lives in reservoirs with stagnant water, often drying up and overgrown with aquatic vegetation. In the dry season digs in the ground \
