List of Top 20 Smallest Animals in the World

Dwarf Three-Toed Jerboa

The endearing Dwarf Three-Toed Jerboa, also known as the Baluchistan Pygmy Jerboa, stands as one of the tiniest rodents globally. These petite creatures typically measure just 4.4 centimeters in length. Thus, primarily inhabit the challenging desert conditions of Pakistan and Afghanistan. They thrive by creating burrows beneath small shrubs and sustain themselves on seeds carried by the wind and tender leaves.

Long-Tailed Planigale

The Long-Tailed Planigale holds the title of being the smallest marsupial on the planet. Thus, ranking among the tiniest mammals ever recorded, measuring a mere 3 to 4 millimeters from top to bottom. To enhance its prowess as a predator (and to better navigate as prey), the entire body of this marsupial is notably flat. This is including its skull, which is only a fifth as deep as it is wide. These adaptations however, enable the Long-Tailed Planigale to adeptly slip into even the most minuscule soil crevices in pursuit of its prey. This diminutive mammal flourishes in the northern regions of Australia, where there is an abundance of cracked soil. Subsequently, there is equally an ample supply of insects, larvae, and even young mammals similar in size.

Pygmy Marmoset

Spotting these miniature monkeys is quite a challenge. They originate from the lofty rainforests of South America, where they expertly navigate through the branches of trees and vines, employing leaps, ducks, and dives. At times, they’ll abruptly freeze, resembling a statue, only to swiftly resume their agile movements, much like a squirrel. Their appearance is akin to a squirrel, with brown fur and a tail that closely resembles that of the rodent. This coloration provides excellent camouflage against potential threats. These pygmy marmosets hold the distinction of being the world’s tiniest monkeys. When fully grown, they can easily fit into an adult’s hand, weighing no more than a stick of butter. Interestingly, their tail is longer than their body, playing a crucial role in maintaining balance as they bound from tree to tree in their arboreal habitats.

They establish their homes in the treetops, displaying a preference for bamboo thickets along riverbanks. Additionally, they seek shelter and forage within the dense vegetation surrounding their abode. Due to their small size, they face predation from birds of prey like hawks and eagles. As well as members of the cat family and snakes. This vulnerability necessitates their swift movements from one location to another. In terms of diet, they favor nectar and fruit in their natural habitat. However, in captive settings such as zoos, they may consume items like mealworms, crickets, hard-boiled eggs, and wax worms.

Bee Hummingbird

The Bee Hummingbird (Mellisuga helenae) is a remarkable species known for being the smallest bird in the world. They are incredibly tiny, with adults weighing only about 2.6 grams. They measure approximately 6.1 centimeters (2.4 inches) in length. Bee Hummingbird are endemic to Cuba and the Isle of Youth, which means they are found nowhere else in the world. in addition, they are known for their vibrant and iridescent plumage. Males have striking iridescent feathers, with patches of bright blue, red, and orange on their bodies. Their primary diet consists of nectar from various flowering plants.

Like all hummingbirds, Bee Hummingbirds are exceptional flyers and can hover in mid-air by rapidly flapping their wings. They have a high metabolic rate, which requires them to consume large quantities of nectar. Also, their nests are extremely small, often constructed from cobwebs, lichens, and plant fibers. The female typically lays one or two eggs, which are about the size of a pea.

Bee Hummingbirds are agile and quick fliers. They are capable of rapid wing beats, with some species known to reach up to 80 beats per second. This animal plays a crucial role in pollination, as they transfer pollen from one flower to another while feeding. This helps in the reproduction of flowering plants. Some populations of Bee Hummingbirds are known to be migratory, moving to different altitudes or latitudes depending on the season and availability of food. These fascinating creatures are not only a testament to the diversity of life on Earth but also play a vital role in the ecosystems they inhabit. They are a subject of fascination for bird enthusiasts and researchers alike.

Madame Berthe Mouse Lemur

The charming Madame Berthe Mouse Lemur bears a resemblance to a mouse. These lemurs possess a greyish-brown body coupled with brown heads and notably large ears. They rely on their keen sense of hearing to pick up bird alarm calls and the calls of fellow lemurs. Thus, using this information to deter potential predators. These lemurs hold the distinction of being the smallest primates globally and are exclusive to Western Madagascar.

They exhibit hues of cinnamon and yellow, accented with light grey. Their under-fur displays a neutral palette of black and grey shades. Madame Berthe Mouse Lemurs lead a solitary lifestyle and are active during the nighttime. Throughout the day, they rest in nests within trees or sheltered holes. However, it is common to observe them engaging in mutual grooming or seeking warmth by huddling together for short periods.

Distinguishing them from other lemur species, Madame Berthe Mouse Lemurs do not undergo hibernation in the winter; instead, they expand their territory to search for food. Their primary diet consists of fruits and flowers sourced from a variety of trees and shrubs. Additionally, they consume insect secretions, arthropods, gum, and small vertebrates like chameleons and geckos. Regrettably, if deforestation persists, experts predict that this invaluable creature may face extinction within a decade.

Speckled Padloper Tortoise

The Speckled Padloper Tortoise, the world’s tiniest, is not suited for domestication as a pet. They boast a golden-beige hue, with their shell adorned with black spots. Their primary diet consists mainly of plants. These tortoises are indigenous to South Africa. Distinguishing this particular species from others in its genus is the presence of five toes on its forefeet, as well as its distinctive speckles. Additionally, they inhabit rocky terrains and outcrops, where they forage for food among the stones. These rock formations offer both refuge from the heat and protection from predators. As herbivores, they consume leaves, flowers, grasses, shrubs, succulents, and forbs. Known for their reclusive nature, they are most active during the early hours of the morning.


As of March 2018, there were only 12 vaquitas remaining in the Gulf of California, thus placing them on the verge of extinction. Vaquitas are a special type of Dolphin. Interestingly, females, with an average length of 55.4 inches, are larger than males. Scientists posit that a significant factor in their imminent extinction is their relative lack of social behavior compared to others in their species. This means that when they find themselves in life-threatening situations, such as being ensnared in gillnets set by fishermen targeting other fish, their distress calls often go unheeded. Without immediate protective measures for this critically endangered species, it is highly likely that they ceased to exist by the close of 2018.

Etruscan Shrew

The Etruscan Shrew holds the distinction of being the smallest mammal in terms of mass. Noteworthy characteristics include its remarkably swift movements and rapid feeding habits, consuming about 1.5-2 times its body weight daily. It possesses a disproportionately large head compared to its body, alongside diminutive hind limbs. In addition, this shrew boasts large ears and features pale fur close to the body that transitions to a light grey hue on its stomach. It sports short whiskers around its mouth, which it employs for nocturnal prey detection. They prefer warm, moist habitats with shrubbery, thus providing them with quick retreat options from potential predators.

Etruscan Shrews create nests in natural crevices and uninhabited burrows. Hence they are frequently gravitating towards rocks, boulders, and ruins, darting in and out of them. They lead solitary lives and are almost constantly in motion, except when seeking refuge or resting. They exhibit peak activity during the night, opting to spend their days near their nests or hiding spots. As omnivores, they consume a varied diet that includes earthworms, larvae, lizards, rodents, and more. keep reading this post on Top 20 Smallest Animals in the World.

Spruce-fir Moss Spider

The Spruce-fir Moss Spider is another minuscule species teetering on the edge of extinction. Primarily found in the American Appalachian Mountains, these spiders belong to one of the tiniest varieties. They are usually measuring a mere three to four millimeters. Their coloration can vary from a light brown to a darker reddish-brown. Also, they do not bear any markings on their abdomen. Since 1995, the inclusion of the Spruce-fir Moss Spider on the Endangered Species List has been attributed to the widespread decline of Fraser Fir trees. This decline has led to a thinning of the forest canopies. Thus, consequently resulting in a scarcity of moss mats crucial to the spider’s survival. In recent years, initiatives have been launched to establish captive breeding programs for these spiders in order to ensure their future existence.

Thorius Arborius

For centuries, these petite salamanders have been navigating the dense vegetation covering the forest floors in Sierra de Juarez, Oaxaca, Mexico. However, their population has started dwindling due to recent logging and agricultural activities. The salamanders are recognized by their lengthy, slender bodies. Thus, typically ranging from 16.1 to 18.4 millimeters, and distinctive large, insect-like eyes. Keep reading to see more animals that made it to the top 20 smallest animals in the world list.

Hippocampus Denise

The Hippocampus Denise is also referred to as Denise’s pygmy seahorse or the yellow pygmy seahorse. It is among the tiniest seahorses ever identified, with a maximum length of about 2.4 centimeters. Although this species is exceptionally rare, it has been spotted in various locations across the western Pacific. These locations include Indonesia, Vanuatu, Palau, Malaysia, the Solomon Islands, and Micronesia. This seahorse exhibits remarkable adaptability, owing to its impressive camouflage capabilities. Like other seahorse species, the male carries and protects the eggs in its ventral brood pouch. However, once fully developed, the offspring leave the pouch to explore independently.

Bumblebee Bat

The Bumblebee Bat, also known as Kitti’s hog-nosed bat, holds the title of being the world’s tiniest bat species. This is due to the fact that it is small enough to comfortably rest in the palm of your hand. Weighing a mere two grams, these bats reside in caves near the Thai community of Tenasserim Hills in Sai Yok District, Kanchanaburi Province. Thus, often forming colonies alongside up to 100 other bats. They are distinctive for their pig-like snouts and coats that range in color from reddish-brown to grey.

Sphaerodactylus Ariasae

Known colloquially as the Jaragua Sphaero or the Jaragua Dwarf Gecko, this is an exceptionally tiny lizard specie. Measuring merely 16 to 18 millimeters in length, this specie is extremely scarce and exclusive to Jaragua National Park. They are located in the far southwest of the Dominican Republic, as well as the nearby Beata Island.
