Top 10 smallest animals in the world

There are interesting and rare creatures on Earth. Scientists spend a lot of time looking for new species. Sometimes they come across amazing representatives of the fauna, which become a sensation. They have such an unusual appearance that they delight biologists. For example, here is our ranking of the smallest animals in the world, which includes miniature birds, fish, amphibians and reptiles.

They are very tiny and fit easily in the palm of your hand. Small individuals differ from their large relatives only in size. Their physiology, habitat and lifestyle are characteristic of all representatives of a particular species. But each creature has individual characteristics. They live in specific conditions and are unique creations of nature.

The article tells about the most interesting animals, which are the smallest on the planet. The rating includes 10 species from all over the world.

10. Homopus signatus (turtle)

Tortoise homopus signatus

An adult is 6-11 cm long and weighs 95-165 g. The miniature land turtle lives in dry African forests and shrub savannas. In order not to fall prey to numerous enemies, she hides under stones. Its light beige, greenish or black color with small spots allows it to be easily camouflaged, practically merging with the surrounding area.

Dwarf reptiles feed on flowers and fruits, eat the stems and leaves of medium-sized plants. In winter, they hibernate for 6-10 weeks. This is necessary to stimulate the ability to reproduce. Outwardly, females differ from males. They are much larger and have a wider and taller carapace.

9. Craseonycteris thonglongyai (bat)

Bat Craseonycteris thonglongyai

A miniature representative of the bats order grows up to 2.9-3.3 cm and weighs about 1.7 g. A cute animal with a fleshy flat muzzle and small eyes a bit like a pig. This similarity is reflected in the name. Otherwise, this bat does not differ from other members of the order. She has rather long and wide wings, no tail, the body is covered with brown fur with a reddish tint. She is the smallest among mammals.

The habitat of these bats is very limited. They are found only in southwestern Thailand and in parts of Myanmar. During the day, the creatures gather in groups and sleep in the limestone caves of small hills, and at night they fly out to hunt. They feed mainly on insects. They rarely breed, usually the female brings only one cub per year.

Interesting fact: for the first time a small bat fell into the hands of scientists in 1973. Their number is very small and amounts to about 500 individuals.

8. Tetracheilostoma carlae (змея)

Змея Tetracheilostoma carlae

The reptile is about 10 cm long and weighs 0.5 g. A rare representative of the well-known family of snakes lives only in Barbados in the Caribbean Sea. In the central and eastern regions of the island, dense forests grow where these creatures are found. The massive felling of trees threatens the species with complete extinction.

The snake hides under rocks and in the grass. She is blind, but this does not prevent her from catching ants and termites. Along with other insects, they are its main food. The little snake is not poisonous and does not pose any danger. It reproduces once a year, laying only one egg. After hatching, the cub is about 5 cm long.

7. Suncus etruscus (shrew)

Shrew Suncus etruscus

A mammal 3-4.5 cm long and weighing 1-1.7 g. The habitat of the dwarf shrew is quite large. It can be found in the foothills and coastal thickets of Southern Europe, North Africa, Central Asia and other regions. Shrews hide in rocky crevices and dilapidated ruins. They dig holes, settle in the hollows of rotten trees and even in human buildings.

The shrew belongs to predators and is nocturnal. The animal feeds on insects, destroying garden pests. Sometimes it attacks very small cubs of lizards, frogs, and some rodents. The shrew has a very fast metabolism, which makes it eat 1.5-2 times more food than it weighs. The female feeds the cubs with milk, but after a month they can already get food.

6. Mellisuga helenae (колибри)

олибри Mellisuga helenae

Males grow up to 5.51 cm and weigh about 1.95 g; females reach 6.12 cm in length, their weight is 2.6 g. The smallest bird in the world lives in the regions of Cuba overgrown with tropical forests. Previously, the number of individuals reached 100 thousand, but due to the massive felling of trees, their number has decreased, and the species is under threat of destruction. Hummingbirds have poorly developed legs, so they spend most of their lives in the air, rising to considerable heights.

Birds feed only on nectar, collecting it on certain plants. Hanging over flowers, individuals make up to 90 strokes every second. When the breeding season comes, they build small nests. In males, the plumage on the head and neck acquires a bright pinkish-red color. In summer, females lay eggs 6.35-11.4 mm in size. After that, the couples break up.

5. Sphaerodactylus ariasae (геккон)

Еккон Sphaerodactylus ariasae

It has a length of only 1.6 cm and weighs approximately 0.2 g. This lizard is the smallest reptile. She lives only in the southwestern part of the island of Haiti, in the territory of the Dominican Republic. Occasionally found on a small island nearby. Lizards were discovered relatively recently, but the species is already endangered.

They differ from other members of the genus not only in size. They have round pupils and small suction cups on their fingers. This explains their name. They lead a terrestrial life, can easily move on smooth surfaces. They can be found in trees and among rocks. Lizards are predators and feed on small insects.

4. Hippocampus denise (seahorse)

Seahorse Hippocampus denise

Reaches a length of only 1-1.5 cm. Small seahorses belong to the needlefish family and live in tropical waters off the coast of Japan, Australia and Indonesia. As solitary creatures, they rarely form small groups. Preferred coral reefs, located at a depth of 70 meters, and thickets of seaweed. Due to their bright coloration, they almost merge with corals.

Dwarf seahorses are sedentary. Having wrapped their tail around a coral branch, they freeze, and they can only be found by chance. Plankton is suitable for them as food. They hunt down microscopic crustaceans and suck them in along with the stream of water. This takes almost half of the time. It is interesting that the offspring of miniature skates are carried by males.

3. Brookesia minima (chameleon)

Chameleon Brookesia minima

Reptile only 0.45-1 cm long. A unique species of lizards, including about 30 subspecies. Its representatives live in the northwest of Madagascar and on a small island off its northern coast. They prefer woodlands. During the day they usually hide in fallen leaves, and at night they climb tree trunks. Miniature chameleons are predators that feed on small insects.

The structure of the body of these reptiles is usual, outwardly they hardly differ from other species. They have a short, almost straight tail, and along the ridge there are two rows of tubercles. Above the eyes are jagged outgrowths. The body color is brownish-brown, reminiscent of the color of fallen leaves. The skin tone of the chameleon changes, which gives it good protection against natural enemies.

2. Paedocypris progenetica (рыба)

Fish Paedocypris progenetica

Sexually mature females are about 7.9 mm long, males grow to 9.8 mm. The small fish belongs to the carp family. She lives in fresh shady ponds and lakes with stagnant water. Leads a bottom life, avoids bright sunlight. It was first discovered on the island of Sumatra, where it is found in very acidic peat bogs. It is also found in other parts of Indonesia.

The fish has a translucent body with a deep reddish-orange color. Males have iridescent spots on their heads. There are pigmented chromatophores that reflect light along the ridge and on the belly. The species is quite rare, since microscopic eggs with a diameter of 0.15-0.3 mm are food for larger animals.

An interesting fact: these beautiful and unpretentious fish are often kept at home in small aquariums.

1. Paedophryne amauensis (frog)

Frog Paedophryne

The Paedophryne amauensis frog is considered the smallest animal in the world. Rare amphibians about 7-8 mm long. The smallest representatives of the vertebrate subtype living in the limited range of Papua New Guinea. They prefer humid tropical forests, where there is a lot of fallen leaves. They have brown skin with reddish-brown and pale bluish patches. The back is dark, and the abdomen and sides are bluish-gray.

Small frogs were accidentally discovered in 2009. Scientists have studied the flora and fauna of the region. And on the sound recordings made, their croaking was clearly distinguished, which was more like the chirping of insects. They became interested in the discovery, searched the forest floor and saw unusual creatures. The species was named Paedophryne amauensis, as the frogs were found near the village of Amau.
