Animal comes in all sizes and shapes. Some are very small, exactly very smaller than you think...
Some invertebrates not even visible to the human eye: some mites are known to measure only 200μm (0.0002mm) in length, a parasitic wasp can be as small as 139μm (0.0001mm) long, and there’s a tiny beetle which is less than 1 mm long. Given the minute size of these animals, who knows what we have yet to discover.
Here is a selection of the smallest vertebrate animals on earth. Some people think the smallest animals are the shortest in height, or length, or the lightest. Which ever way you measure them these really are some amazing little animals.
(These animals are not in order of small size. According to the natural, animals are born with different size, this content just show about the type of animal which is far smaller than the other type of its genres. For example: Pygmy Rabbit is far smaller than other rabbits, but not smaller than other general snakes...)
Pygmy Marmoset
The Pygmy Marmoset or Dwarf Monkey (Cebuella pygmaea) is the world’s smallest monkey. It is native to the rainforest canopies of Brazil, Columbia, Ecuador, Peru and Bolivia. It is one of the smallest primates, and the smallest true monkey, with its body length ranging from 14 to 16cm (excluding the 15 to 20cm tail). Males weigh around 140g, and females only 120g. They weigh only 15g at the time of birth. The lifespan of these monkeys is 11 to 16 years. They usually give birth to twins.
Madame Berthe's Mouse Lemur
The smallest primate is the Madame Berthe's Mouse Lemur (Microcebus berthae), found in Madagascar, with an average body length of 92 mm and weight of around 30g. It is found in the Kirindy Mitea National Park in Western Madagascar.
Pygmy Rabbit
The Pygmy Rabbit (Brachylagus idahoensis) is the smallest rabbit. It is found in North America. The adult pygmy rabbit weighs about 400 g having a body length of 24cm to 29cm; females are slightly larger than males. They are generally limited to areas on deep soils with tall, dense sagebrush which they use for cover and food. Extensive, well-used runways interlace sage thickets and provide travel and escape routes from predators such as weasels.
Paedocypris
The Paedocypris (Paedocypris) is the smallest fish, at only 7.9mm in length. This is also considered as the smallest vertebrate. It is found in the peat swamp forests of Indonesia’s Sumatra Island and can survive extreme drought in part due to their small size (just 7.9 mm long at maturity). Much of their habitat is acid water, with pH as low as 2.9. The members of the genus are thought to be highly endangered.
Gold Frog
Smallest frog in the Southern Hemisphere is the Gold or Brazilian Frog (Psyllophryne Didactyla). Adult Gold Frogs measure grow to only 9.8 millimetres in body length (with legs drawn in). Equally small is the smallest frog in the Northern Hemisphere, only recently discovered (1996) in Monte Iberia, Cuba. It doesn't have a common name yet, but its scientific name is Eleutherodactylus iberia.
