3: "All frogs are basically small and green." Fiction

Frogs come in a wide range of sizes and a rainbow of colors. The goliath frog of West Africa is the size of a small dog, measuring about 15 inches from nose to rump. On the other end of the scale is Pyllophryne didactyla, the world's smallest frog, which is found in Brazil. This little frog is about the size of a firefly and could sit easily on top of a pencil eraser.
