World’s Smallest Frog

World's Smallest FrogWorld’s Smallest Frog, Perched on a coin the size of a 5p piece, there is still probably room for two. At half the size of a Smartie sweet, this is the world’s smallest frog, measuring just a quarter of an inch long.

Scientists discovered the previously unknown creature, speckled in red and black, sitting on a leaf on the tropical island of Papua New Guinea.

At just 7.7mm in size when fully grown, it has snatched the title as the smallest of the world’s 60,000 vertebrates – creatures with a backbone – previously held by a tiny Indonesian fish which measures 7.9mm.

Experts are baffled by the find as it was previously thought extreme body size in vertebrates, whether large or small, was associated with living in water.

Professor Chris Austin, of Louisiana State University, who discovered the frog on a three-month field trip to the Pacific island, said by contrast these creatures make their habitats on fallen leaves on the floor of tropical rainforests.
