Oct 7

Harvey Ball created the original smiley face in 1963. This famous symbol is used worldwide to represent good will and happiness.

Since 1999, the first Friday in October is known as World Smile Day, a time to remember the true meaning of the smiley face, encourage acts of kindness and, of course, spread smiles.

If you’re feeling a bit grumpy or having a bad day, don’t worry…    
            

               Turn that frown. . .                                             . . .upside down

The Weddell seal is certainly making the effort for World Smile Day!

It is often said that smiling is contagious, so let’s hope these gleeful grins on ARKive leave you positively beaming.

The ember parrotfish’s teeth are fused into a beak, creating a dazzling smile. It uses its beak to feed on algae by scraping it from the reef.

This young mountain gorilla could do with a scale and polish! Eating plants with a high tannin content is thought to contribute to the black tartar staining on the teeth. The tartar accumulates over time and gum disease is a common problem in older gorillas.

Green grin

The beautiful green and golden bell frog looks very relaxed in the water, although it is equally as happy foraging and basking in dense vegetation and grassy habitats.

The rare recurve-billed bushbird, also known as the ‘smiling bird’ has an unusual appearance, caused by its up-turned bill. It uses its bill to break open small twigs and bamboo in search for arthropods.

Why not join in on World Smile Day and “Do an act of kindness. Help one person smile!”
