Nature is full of surprises. Some animals are so tiny they can sit on your fingertip. From the world’s smallest frog to a glowing mini shark, here are six unbelievably small creatures.

#1 The smallest frog

Measuring just 7.7 millimetres, Paedophryne amauensis is the smallest known vertebrate on Earth. Discovered in Papua New Guinea, this frog is about the size of a housefly and lives among forest leaf l

#2 The smallest gecko

The Jaragua sphaero is one of the tiniest lizards in the world. Growing to only 16 millimetres, this dwarf gecko lives in the Caribbean and can easily perch on a coin.

Madame Berthe’s mouse lemur weighs about 30 grams and measures around 9 centimetres long. Found in Madagascar, this nocturnal primate leaps through trees and feeds on insects and fruit.

#4 The smallest shark

The dwarf lanternshark grows to around 20 centimetres long, making it the smallest shark species. Living deep in the ocean, it produces a bioluminescent glow that helps camouflage it underwater.
