In this article you will find a list of the world’s smallest animals as well as exciting information and pictures!
All data in this list relate to the so called snout-vent length, i. e. the length has been measured from the snout/tip of the nose to the root of the tail. Legs, arms, and the tail have not been considered, because the lengths of arms, legs, and tails often significantly differ within one species. Often curvatures and joints make measuring even more difficult. Therefore the snout-to-vent-length is simply more informative.
Below the chart there is even more information! Do not miss the picture of the smallest pony and the smallest chameleon in the world :)

These animals are not much bigger than fluffy toys! The Falabella horse is particularly cuddly. The pony does not get bigger than 33.85 inch (86 cm), which already is incredibly small.
The smallest living Falabella does only measure 17.51 inch (44.5 cm), is named “Thumbelina”, and has got an entry in the Guinness Book of Records in 2006.
With only 13,97 inch (35.5 cm), “Little Pumpkin” was even smaller. It weighed only 10 kg and could be easily carried around on the arm. A handbag horse as it were.
Mini Mini Mini Frog
Smaller than a coin and yet fully grown: the smallest amphibian in the world is a narrow-mouthed frogs (Paedophryne amauensis). It is also the smallest vertebrate in the world.
The frog lives in Papua New Guinea and was discovered just in 2009. That's not surprising, considering its size! Unlike other frogs, it does not develop from a tadpole, but hatches ready from the egg.
The hummingbirds are cute little hummers, too. They use their long bills to slurp delicious nectar.
The smallest hummingbird is the bee hummingbird, which also is the world’s smallest bird: It does not get bigger than 57 mm and not heavier than 0.05 oz (1.6 g).
The vervain hummingbird is a few millimeters bigger, but it lays the world’s smallest bird’s eggs. In 1998, a vervain hummingbird laid an egg that was not even 0.39 inch (10 mm) long and just weighed 0,01 oz (0.365 g). (Our photo shows a Costa’s hummingbird.)
The Smallest Human Beings
Chandra Bahadur Dangi from Nepal is said to be the smallest man of the world. He was born in 1939 and was only 1.79 ft (54.6 cm) tall and weighed 31.9 lb (14.5 kg) in 2012. The world’s smallest woman is Jyoti Kisanji Amge from India. She was born in 1993 and was just 2.06 ft (62.8 cm) tall at her 18th birthday in 2011.
