Delhi and Mumbai are the most popular destinations, with each seeing over 4.5 million visitors in 2014. Additionally, the introduction of a new visa-on-arrival process for 46 countries, including the US, Germany and Australia, has helped encourage visitors to India. Vietnam saw three of its cities in the top 100 for the first time: Ho Chi Minh City, Hanoi and Halong.
In total there are 13 tree kangaroos species in Australia, Papua New Guinea: all face the same threats of habitat loss. The stocky wallaroo, with his shaggy coat and short limbs, is well-adapted for leaping around rocks.
The Grey kangaroo is the next largest. Two species, the Western and Eastern grey, belong to this family. The Western kangaroo lives as you might expect in Western Australia, but the Eastern kangaroo likes forest and grassland areas of Australia's east coast, and is the only kangaroo species on the island of Tasmania. The species has a woolly textured coat, compared to the Red kangaroo's silkier one, and is a grayish-brown color. Males measure up to 5 feet in height and weigh about 145 pounds. Females are only 4 feet tall by comparison and weigh in at 77 pounds.
