One thing that natural history television shows and books have taught us is that animals come in all shapes and sizes. Some are huge beasts that easily dwarf humans, such as elephants or whales, while others are tiny creatures that can easily fit into the palm of your hands. Finding small animals isn’t that difficult, yet there are some very surprising examples that are closely related to other living things that usually come in far greater sizes.
Pygmy Marmoset
The Pygmy Marmoset is not only the smallest monkey in the world but it is also one of the smallest primates to have ever existed. Weighing just 0.2 pounds, they generally grow to be around six inches long. Living in the rainforests of South America, they eat tree sap, bugs, insects and tiny lizards.
