Shoulder Height and Body Length
All data in this list relate to the shoulder height or the so called body length. This is the length from the ground to the shoulder or thei length from the tip of the nose to the root of the tail. Head, neck, 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.
The Smallest Horse Breed
The Falabella pony is the smallest horse breed in the world. It does not get bigger than 33.85 inches (86 cm), which already is incredibly small. The smallest living Falabella does only measure 17.51 inches (44.5 cm), is named “Thumbelina”, and has got an entry in the Guinness Book of Records in 2006. With only 13,97 inches (35.5 cm), “Little Pumpkin” was even smaller. It weighed only 22 pounds (10 kg) and could be easily carried around on the arm. A handbag horse as it were.
The Smallest Amphibian
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 Smallest Bird
The smallest hummingbird is the bee hummingbird, which also is the world’s smallest bird: It does not get bigger than 2.2 inches (57 mm) and not heavier than 0.05 ounces (1.6 grams). 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 inches (10 mm) long and just weighed 0,01 ounces (0.365 grams).
The Smallest Humans
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 feet (54.6 cm) tall and weighed 31.9 pounds (14.5 kg) in 2012.
