The Best Photos From This Year's Comedy Wildlife Awards

Finalists include a pair of monkeys caught in the act, two zebras that look like an a cappella singing duo and a duck being sprayed by rhino pee.

The awards, now in their fourth year, are a free-to-enter celebration of funny photos that illuminate the brilliant diversity of the world's wildlife.

"Each year we see a wider variety of of species doing funny things, whether it's a very naughty penguin or dancing lions, a chillin' chimp or even bee-eaters having a shouting match," Paul Joynson-Hicks, a British photographer who co-founded the awards, told CNN.

The competition's results will be revealed on November 13, with the winner getting a one-week safari in Kenya's Masai Mara. The contest, aimed at highlighting the importance of conservation, is run in conjunction with global wildlife charity Born Free Foundation.

The world has seen an astonishing 60 percent decline in the size of populations of mammals, birds, fish, reptiles, and amphibians in just over 40 years, according to last year's Living Planet Report by the World Wildlife Fund.
