Animals happy on a blue Monday

It may be a blue Monday, but at least the animals are happy! These hilarious shots show a variety of euphoric animals enjoying a hearty belly laugh.

The pictures, captured by a host of photographers around the world, prove that a drop of sunshine can transform the mood of all creatures great and small.

A mischievous-looking macaque snapped a selfie of herself posing in Indonesia, while a grinning gorilla is seen creased up as he enjoys life. Another shot shows a raccoon that looks like he's just heard the punch line of a joke, and a chuckling cheetah was caught throwing his head back midlaugh.

Even those with arachnophobia won't be able to help themselves from having a smile at the aptly named Hawaiian happy-face spider who was pictured with a grin plastered across his back. (Caters News)
