The world is full of robber flies—approximately 7,000 species have been recognized worldwide and 1,000 are native to North America.
1. Javan Rhinos. Once found throughout south-east Asia, Javan rhinos have suffered a staggering decline in their numbers due to hunting and habitat loss.
What is the largest animal in Australia? The Red Kangaroo is the largest native terrestrial animal in Australia. The largest recorded male Red kangaroo stood 2.1 meters (6.9 ft) tall and weighed 91 kg (201 lb).

Losing hundreds of species over 500 or so years may not seem significant when there are millions more still living on the planet. But the speed at which species are now vanishing is unprecedented in the last 10 million years. "We are losing species now faster than they can evolve," O'Brien said.
Among animals, insects are the most species-rich taxonomic group making up more than 70 percent of the total.
