This beautiful animal is Red-bellied short-necked turtle. It is found in Australia and Papua New Guinea, and in Australia it is highly endangered. These stunning colours are highly pronounced as infants and juveniles, but fade as they age. They reach about ten inches (25 cm) in length.

Inca terns are unique and beautiful birds—slender with white-tipped gray feathers, a white curly moustache, yellow lips and a bright orange-red bill. They have a distinctive call that sounds like a high pitched laugh, which is often accompanied by bowing gestures.

Inca terns are natives of the western shoreline of South America and the islands located offshore. They are especially abundant in northern Chile and Peru in the summer. They migrate in winter, venturing to Ecuador and central Chile.

Inca terns swoop down and pluck fish from near the water’s surface. They also sometimes get scraps left behind by whales, or flock to where sea lions are eating on rocks, to steal stray bits of food.

This is the Northrop Grumman B-2 Spirit (stealth bomber). This machine is capable of pin-point strikes on most any hardened target available such as underground bunkers. Needless to say, it is also capable of delivering nuclear weapons.

This stealthy aircraft was designed in a way that enemies could not anticipate its arrival, but its 22,600 Kg bomb load and a multitude of nuclear missiles would ensure they'd know when it had arrived. Named the B-2 Spirit, its advantage in battle is derived from its designation spirit; it operates like a ghost.
