Rating of the smallest animals


I invite you to the world of the smallest animals on our planet. I will make a reservation that we will only talk about those that can be seen without a microscope and touched with your hands.

Scientists claim that the smallest land animal in the world is the frog Paedophryne amanuensis. The minimum length of this vertebrate is about 7.7 mm, and the maximum is not more than 11.3. Females of these frogs are larger than males. The brown color of the body perfectly masks them on the ground, tree trunks, among the foliage. These frogs were discovered recently, found in the southeast of Papua New Guinea at an altitude of 900 meters above sea level.

In water, the smallest animal is recognized as the fish Paedocypris progenetica. It can be found in peat bogs and sewage streams in Indonesia. Females of these fish reach the largest size, but even they do not exceed 10.3 mm in length. Record, officially registered size - 7.9 mm. An unusual fact is that these tiny fish belong to the cyprinid family (oil painting: went fishing for carp.).

Chameleon Lesser Brukesia (Brookesia minima) lives in the tropical forests of Madagascar. This is the smallest lizard in the world. But you can see it, unless by accident, because the size of an adult does not exceed 1.2 cm, and the ability to change the color of the skin depending on the environment even in this tiny species is preserved.

The shortest snake Tetracheilostoma carlae lives in the Caribbean. The baby from the family of narrow-snakes grows up to 100 mm in length. Shorty lives under stones and in the soil, and feeds on ant eggs and termites.

Well, everyone has heard about this pichuga. Hummingbirds mainly live in Cuba. Weight does not exceed 2 grams, and the length is not more than 6 cm, this together with the beak. If you compare with some medium sized beetle, then the weight of this insect is 20 times more than a hummingbird bird, so it can be difficult to distinguish from an ordinary bee, especially since they feed only on nectar. And the sound that this pichuga makes is very reminiscent of the “buzzing” of insects. Another such fact: the length of the egg of a dwarf hummingbird is from 6 to 11 mm.

The smallest mammal - a dwarf polydent (Suncus etruscus) - grows up to 3-4.5 cm in length (without tail). The tail length is sometimes comparable to body length (3-3.5 cm). The mass of her body is about 1-1.7 g. Outwardly, the multi-tooth resembles an ordinary shrew in miniature. Despite its size, the multi-tooth is a predator. It eats insects, including pests, thereby benefiting man and nature.

The smallest primates are dwarf marmosets. They live in South America and reach "gigantic proportions" - from 10 to 15 cm. Its weight does not exceed 150 grams. The tail of the marmoset is longer than the body - 20-22 cm. Due to the thick coat, it seems more than it actually is.

To what mother nature invented, a man had a hand in it. As an example, a few miniature pets.
Dwarf horse. If you compare a pony (just a little horse) and this baby, then the first is just a giant. Zoologists cannot understand why the horse stopped growing and remained a dwarf. The height at the withers of such a horse is from 40 cm, and the weight is about 30 kg. In the US, these babies are becoming popular pets. The most interesting thing is that they do not have fleas, and US veterinarians recognized them as the best guide for blind people. By the way, the cost of such horses - from $ 40,000

Mini-goby and mini-cows. In India they brought out dwarf zebu. An adult animal reaches a height of 81 cm, and weighs almost 80 kg. They look more like calves, only with a small hump on the scruff of their neck. Dwarf cows today have about 26 breeds. Several of these cows were brought to the United States and sent to the zoo. After some time, the ranchers began to breed them for a rodeo. And then these cows turned into pets. In size, they are like a dog: height - 80-90 cm, weight - 90-150 kg. The difference is that these "handsome" give 3 liters of milk per day.

Many breeds of small dogs were bred that fit comfortably in a handbag. And the smallest dog in the world is recognized as a Chihuahua from Puerto Rico, whose height is only 9.6 cm.

And finally, the smallest cat in the world. His name is Mr. Peebles and he was born in the US state of Illinois. Mr. Pibbles set a Guinness record as the smallest feline. It weighs only 1.5 kilograms, and its length (without tail) is about 15 centimeters.

Micro-fowls Paedophryne

The smallest land animal. Mikrokvakshi (lat. Paedophryne) - This little frog belongs to the family of narrow-breeds, or micro-frogs.

It is considered the smallest in the world, its length does not exceed 7.7 mm, but sometimes it grows to 11.3 mm. This baby was discovered recently; it was found in Papua New Guinea. Females of these amphibians are slightly larger than males. Due to its brown color, this frog is not visible either on the ground, or among foliage, or on tree trunks.

Fish Paedocypris progenetica

The smallest aquatic animal. Fish Paedocypris progenetica - recognized as the smallest inhabitant of water bodies. It can be found in the sewage streams and peat bogs of Indonesia.

The largest are the females of these fish, but they are also small - 10.3 mm in length. The smallest officially recorded length of this fish is 7.9 mm. Interestingly, these crumbs belong to one of the largest families of cyprinids!

Chameleon Lesser Brukesia

The smallest lizard in the world. Chameleon minor brukesia (lat. Brookesia minima) - an inhabitant of the rainforests of Madagascar and the smallest lizard.

Due to its tiny size (1.2 cm) and the ability to change color (in fact, like all chameleons), it is not easy to notice in natural conditions. It was discovered in 2007 near the island of Madagascar, and it was possible to describe this chameleon only in 2012.

Denis Seahorse

Denis Seahorse (lat. Hippocampus denise) - Another baby and a master of disguise. It lives in the warm waters of the western part of the Pacific Ocean at a depth of about 16-90 m.

One can only be surprised at how such a tiny creature, whose length does not exceed 1 cm, manages to survive among the cruel world of marine life. And it turns out you can survive: it perfectly disguises itself as the gorgonians or corals in which they live, painting their body in orange or yellow.

Dwarf gecko

Dwarf gecko (lat. Sphaerodactylus ariasae) - a small creature, the size of which does not exceed 1.6-1.8 cm, fits easily on the thumbnail. This baby weighs just nothing - 0.2 grams.

It is worth noting that this gecko was discovered in 2001, but, despite this, it is already under the threat of complete extinction. You should probably thank those researchers who timely calculated its number, in view of which the dwarf gecko was immediately listed in the Red Book.

Jellyfish irukanji

Jellyfish Irukanji (lat. Carukia barnesi) Is an unusually poisonous and very small creature that lives in the Pacific Ocean, off the coast of Australia. Outwardly, this jellyfish resembles a white translucent bell. Its dimensions are only 12x25 mm, and tentacles are from 1 mm to 1 m long.

But not only because of its size, it attracted the attention of researchers. This baby can not only paralyze a person, but even kill him. The antidote does not exist yet, since this species has not yet been sufficiently studied, and therefore its poison, too.

Hummingbird Bee

The smallest bird. Hummingbird bee (lat. Mellisuga helenae) - the smallest among birds.

It was discovered in 1844 in Cuba, Juan Cristobal. Her weight is only 1.6-2 g, and her body length is 5-7 cm. She eats like all hummingbirds - with nectar of flowers. Interestingly, the heart of this miniature bird beats with a frequency of 300-500 beats per minute.

Dwarf shrew

The smallest mammal. Dwarf shrew, or Etruscan shrew (lat. Suncus etruscus) - an inhabitant of southern Europe, southern Asia and northern Africa.

Many scientists believe that the animal should exist normally, it should weigh at least 2.5 g, but this baby, whose weight is only 1.5 g and body length is 3-4.5 cm, lives and lives perfectly. But for this she has to eat all the time, and therefore she hardly sleeps. The heart rate of a dwarf shrew is 1300 beats per minute.

Pig Bat

Pig-bat, or bumblebee mouse (lat. Craseonycteris thonglongyai) - lives in the west of Thailand and southeast of Burma.

Its mass is only 2 g, and the body length is not more than 4 cm. According to the latest data, their number is several hundred individuals, therefore, it belongs to vulnerable species listed in the Red Book. In flight, it resembles a hummingbird.

Snake Tetracheilostoma carlae

The snake Tetracheilostoma carlae is the shortest snake in the Caribbean.

This baby grows up to 100-104 mm in length, it is easy to confuse it with an earthworm. Likes to hide under stones, as well as in the soil. It feeds on termites, ant eggs and other small insects. Not poisonous.

In order to survive, many creatures during evolution have to take the most bizarre shapes and unusual sizes. The most striking evidence that nature has prepared many surprises for us are miniature animals of our planet.


It lives in the Andes, in the southern part of Peru in tropical forests.

The adult frog reaches a length of only 10–13 mm.

She lays only 2 eggs and looks after them until the frogs hatch.

Which, bypassing the stage of the tadpole, are born full-fledged frogs.

Among the fish, the smallest was a relative of the carp Paedocypris progenetica.

Its length in males is only 10.3 millimeters, and in females - 7.9 mm.

It lives in peat bogs of Indonesia.

These fish have almost no cranial bones, and the body is so transparent that you can see all the internal organs.


Among the chameleons, the tiniest is Brookesia micra.

It lives on the island of Nosy Be off the northwestern coast of Madagascar.

In length reaches only 28 mm, it is able to change the color of the skin for masking.

Denis Seahorse

A funny predator that feeds on carrion, insects, bird eggs, has incredibly large ears that allow them to catch the slightest rustle around. In addition, the Phoenixes are excellent jumpers: they are able to bounce to a height of more than half a meter. Such features of the animal make it an unsurpassed predator, which is difficult to hide from and escape from. Phoenixes live more often in the Sahara. Due to their small size and beautiful appearance, they are now more and more often bred as pets, but if such a pet is expensive, it will be quite expensive.

9. Starbringer

Stargazer not only one of the smallest, but also unusual animals in the world. The inhabitant of North America from the mole family has growths on its head that resemble the shape of a star. Hence the name of the animal. On average, the size of star-carriers is 1 decimeter in length and weight is less than 100 g. These representatives of the mole family, like their closest relatives, live underground. Starfish are also excellent swimmers who prefer to hunt at the bottom of ponds, but can earn their livelihood on the surface of the earth. Monogamy is characteristic of these unusual animals: the female and the male continue to live together even after the mating season.

The length of the body of this animal ranges from 3-5 centimeters, and the average body weight is only 1.5 grams. The habitat of dwarf moths is chosen by thickets near ponds, as well as mountain gorges. Also, this amazing animal can be found on cultivated land by humans - gardens and vegetable gardens. They are able to independently dig holes, but often occupy the dwellings of moles. Despite their tiny size, these are natural predators that boldly attack not only insects, but also animals that exceed their size - frogs, lizards, young rodents, etc.

2. Dwarf mouse lemur

Dwarf mouse lemur refers to the smallest animals in the world, whose body length is only 10 centimeters, and body weight does not exceed 50 grams.

Interestingly, the brain of the shrew is the largest in proportion to the body among all other animals, including humans.

Cape Speckled Tortoise

This adorable turtle is mottled flat; it lives in South Africa. Males of this species are 6–8 cm in size, and females are 10 cm. They live on stone elevations, where they hide from predators in crevices and get vegetation for food.


Hummingbird - this bird received the status of the smallest warm-blooded vertebrate. With a body length of only 5.7 cm and a width of 2-3 cm and weighs some 1.8 g. Despite its tiny size, the hummingbird becomes so bold during hatching that it attacks birds much larger than itself.

Barbados snake

The Barbados narrow-snake, or carla, is the least known representative of this species in the world. The length of the adult is 10 cm, and the largest is only 10.4 cm. This species of snake was discovered in 2008 on the island of Barbados, near the Caribbean Sea, its main habitat is the eastern and central forests. The favorite pastime of these kids is to hide under stones or in the grass.

Paedophryne amauensis

This baby from the sight of narrow-frogs, the smallest that a man has ever met. Her body is 7.7 mm long and this makes her an amazing vertebrate that has reached the smallest size.

It was the top of the smallest animals ever discovered by humans. Maybe someday you will be able to see these amazing animals with your own eyes.
