The number of mountain gorillas in the world has increased by more than 26% in regions in eastern Africa, according to a survey released in January. CNN has this report.

This increase brings the world population to 786 mountain gorillas, the organization said.

"The mountain gorilla population has made an absolutely remarkable recovery. We are very pleased to see yet another increase in the numbers of this critically endangered species," said Allard Blom, a director with the World Wildlife Fund.
