These high-climbing bright orange animals represent one of the world's most endangered great apes. Zoo visitors are treated to the sight of orangutans swinging on ropes among the trees. Two of the adult males have been prioritized for breeding by the orangutan Species Survival Plan of the American Zoo and Aquarium Association. If all goes well, zoo visitors can look forward to baby orangutans in the future. Native to southeast Asia, muntjac deer are found in woodlands and dense tropical forests.
Males have antlers, through they prefer to use their long canine teeth to defend themselves.
At maturity, muntjacs weigh between 20 and 25 pounds. Muntjac deer thrive in captivity and are bred frequently at zoos worldwide. Although wild populations are not threatened, they are often hunted for their meat and skins. Because they use their long front teeth to graze on tree bark, thus destroying trees, they are sometimes considered a nuisance. They have tiny claws and their toes are only partially webbed, this adaptation gives them a highly developed sense of touch.
