These comical creatures are clearly up FUR a laugh in these sidesplitting images which show a variety of ecstatic animals enjoying a good old chuckle. The hilarious snaps, taken by a whole host of photographers from around the globe, prove life in the jungle is most definitely jolly, as creatures from an orangutan to an elephant seal are pictured mid-laugh. A cheery chimpanzee can be seen sporting a toothy grin as he enjoys life at Chimfunshi Wildlife Orphanage in Zambia. And a pot-bellied pig is clearly tickled pink at his home in Lower Saxony, Germany. In another image an Icelandic horse appears to crack up when he spots a photographer's camera, while a chuckling cheetah creases up in Kenya.
