Pictures: Secrets of world's wildlife caught on camera

The first global camera-trap survey of mammals captures rare glimpses of more than 100 different species.
It's not often you get to see shots like this. This jaguar was caught on camera in Costa Rica as part of the first global camera-trap survey of mammals, which has recorded rare glimpses of 105 different species.

In larger protected areas, researchers also found more animals like different diets, including carnivores, herbivores and species that favour fruit, like these southern pig-tailed macaques which were photographed in Indonesia.

The largest animal caught on camera was this African elephant in the Udzungwa Mountains, Tanzania, weighing almost four tonnes. The smallest was a Linnaeus's mouse opossum in Suriname, South America, which weighs just 26g.

Scientists studying the photos found that areas of continuous forest had more different species as well as a bigger variety of animal sizes. These forests were home to more large mammals, such as these mountain gorillas recorded in Uganda.

Insect-eaters such as this giant anteater, photographed in Brazil, were found to be more vulnerable to habitat loss. They were among the first species to disappear from areas under threat.

A Lowe's servaline genet was rediscovered by a hidden camera-trap in 2002, and one's been snapped in the latest study by the Tropical Ecology Assessment and Monitoring Network (Team) at Conservation International too.

Technicians fitted 420 cameras in seven protected areas across the Americas, Africa and Asia. The cameras have taken more than 52,000 photos over four years, in what is the largest camera-trap study of any animals made worldwide.

These endangered chimpanzees were caught on camera in Uganda. So were some of the people that hunt them. One of four mammals worldwide are said to be under threat from hunting, conversion of land for agriculture and climate change.

According to the researchers, the study has given them a crucial foundation for the future protection of different species, including the near-threatened South American tapir. The Team network has now extended its work to a total of 17 sites worldwide.
