The animal kingdom is full of fascinating creatures, from the mighty elephants to the tiny hummingbirds. Among the smallest members of the mammalian class, there are species that defy expectations with their diminutive size. In this article, we’ll explore the top 10 lowest mammals, highlighting their unique adaptations, habitats, and ecological significance. From tiny rodents to miniature marsupials, these diminutive mammals prove that size is no barrier to survival and success in the natural world.
Top 10 Lowest Mammals In The World
1. Etruscan Shrew (Suncus etruscus): The Smallest Mammal on Earth
The Etruscan shrew holds the title of the world’s smallest mammal, measuring just 3 to 5 centimeters in length and weighing a mere 1.2 to 2.7 grams. Found in Europe, Asia, and Africa, these tiny insectivores are active hunters, feeding on insects, spiders, and other small invertebrates. Despite their minuscule size, Etruscan shrews have a voracious appetite, consuming up to twice their body weight in food each day to fuel their high metabolism.

2. Bumblebee Bat (Craseonycteris thonglongyai): A Miniature Flying Mammal
The bumblebee bat, also known as Kitti’s hog-nosed bat, is the smallest bat species and one of the smallest mammals in the world. Found in limestone caves in Thailand and Myanmar, these tiny bats have a wingspan of just 15 to 16 centimeters and weigh around 1.5 to 2 grams. Despite their diminutive size, bumblebee bats are capable of sustained flight, using their tiny wings to forage for insects in the night sky.
3. Pygmy Jerboa (Salpingotulus michaelis): A Desert Acrobat
The pygmy jerboa is a tiny rodent native to the deserts of Central Asia. Measuring just 4 to 6 centimeters in length and weighing around 3 to 4 grams, these pint-sized rodents have long hind legs adapted for hopping and jumping across the sandy terrain. Pygmy jerboas are nocturnal creatures, emerging at night to forage for seeds, insects, and plant matter, using their keen senses to navigate the harsh desert environment.
4. Baluchistan Pygmy Jerboa (Salpingotulus baluchistanicus): A Close Relative of the Pygmy Jerboa
The Baluchistan pygmy jerboa is another diminutive rodent species found in the deserts of Iran and Pakistan. Similar in size to the pygmy jerboa, these tiny rodents have long hind legs and a tufted tail, which they use for balance and agility as they navigate their sandy habitat. Baluchistan pygmy jerboas are skilled burrowers, excavating intricate tunnels in the desert sand to escape the heat and predators.
5. Etruscan Pygmy Shrew (Suncus etruscus): A Close Relative of the Etruscan Shrew
The Etruscan pygmy shrew is a close relative of the Etruscan shrew and shares its tiny stature. Found in Europe, Asia, and Africa, these tiny insectivores are similar in size to their larger cousins, measuring just 3 to 5 centimeters in length and weighing around 1.2 to 2.7 grams. Etruscan pygmy shrews are agile hunters, using their keen senses to detect and capture prey in their leaf litter habitats.
6. Kitti’s Hog-Nosed Bat (Craseonycteris thonglongyai): Another Name for the Bumblebee Bat
Kitti’s hog-nosed bat, also known as the bumblebee bat, is the smallest bat species and one of the smallest mammals in the world. Found in limestone caves in Thailand and Myanmar, these tiny bats have a wingspan of just 15 to 16 centimeters and weigh around 1.5 to 2 grams. Despite their diminutive size, Kitti’s hog-nosed bats are capable of sustained flight, using their tiny wings to forage for insects in the night sky.
7. Etruscan Water Shrew (Neomys anomalus): A Semi-Aquatic Tiny Mammal
The Etruscan water shrew is a small semi-aquatic mammal found in wetlands and waterways across Europe and Asia. Similar in size to the Etruscan shrew, these tiny mammals have a streamlined body and partially webbed feet adapted for swimming and diving. Etruscan water shrews are skilled hunters, preying on aquatic insects, fish, and amphibians in their freshwater habitats.
8. Least Weasel (Mustela nivalis): A Tiny Predator of the Northern Hemisphere
The least weasel is the smallest carnivorous mammal in the world, found in the northern regions of Europe, Asia, and North America. Measuring just 11 to 26 centimeters in length and weighing around 25 to 150 grams, these tiny predators are skilled hunters, preying on small mammals, birds, and insects. Despite their diminutive size, least weasels are agile and voracious hunters, able to take down prey much larger than themselves.
9. African Pygmy Mouse (Mus minutoides): A Tiny Mouse of Sub-Saharan Africa
The African pygmy mouse is one of the smallest rodents in the world, native to the grasslands and savannas of sub-Saharan Africa. Measuring just 5 to 8 centimeters in length and weighing around 5 to 10 grams, these tiny mice are skilled climbers and burrowers, using their sharp claws and keen senses to navigate their grassland habitat. African pygmy mice feed on seeds, insects, and plant matter, foraging primarily at night to avoid predators.
10. Eurasian Pygmy Shrew (Sorex minutus): A Small Insectivore of Europe and Asia
The Eurasian pygmy shrew is one of the smallest mammals in Europe and Asia, measuring just 3 to 5 centimeters in length and weighing around 2 to 6 grams. Found in a variety of habitats, including forests, grasslands, and wetlands, these tiny insectivores are agile hunters, using their sharp teeth and keen senses to capture prey. Eurasian pygmy shrews are active year-round, foraging for insects, spiders, and other small invertebrates to sustain their high metabolism.
