List of 10 Animals With Hands
At the forefront of our list of animals with hands are the enchanting lemurs, exclusive to the island of Madagascar and a handful of smaller islands along the African coast.
Native solely to Madagascar, lemurs boast a diverse range of about 100 species, some of which are remarkably tiny in size.
While all lemurs possess hands, the scientific community, including New World Monkeys, debates the nature of their thumbs. Some argue that their thumbs are pseudo-opposable, not fully opposable. Regardless, lemurs effortlessly utilize their hands to grasp branches and consume their food.
These diurnal animals, adept at ground and tree habitats, form troops of up to 25 individuals. Social hierarchies within these troops are determined by sex.
Lemurs belong to the primate family and share Madagascar with other primates like pottos and lorises. The smallest lemur species measures a mere 3 inches, while others reach several feet in height. Their pseudo-opposable thumbs, akin to other primates, play a crucial role in navigating their arboreal surroundings and manipulating their sustenance.
Fun Fact: Lemurs, the exclusive primates of Madagascar, boast the unique distinction of being the only primates, aside from humans, to have blue eyes.
Koalas, the charming and often lazily characterized creatures from Australia, defy expectations with their extraordinary hands. They don’t just have opposable thumbs – they have two on each front paw and one on each foot, totaling six opposable digits. This unique hand structure is a game-changer for their tree-dwelling lifestyle.
The second thumb, cleverly positioned instead of the little finger, is the secret behind koalas’ remarkable ability to climb trees rapidly and securely grasp branches. These additional thumbs provide exceptional grip strength, vital for their life spent predominantly in tall eucalyptus forests.
Koalas are one of the few mammal species with fingerprints, emphasizing their distinctive hand anatomy. With two opposable thumbs on each hand and an opposable toe on each foot, they hold the record among animals for the number of opposable digits. This adaptation enables them to maneuver among branches efficiently.
Although not officially listed as endangered by Australia, the koala population has dwindled to less than 100,000 in the wild over the last century. Their unique hands, equipped with two opposable thumbs, play a crucial role in their survival, making them a fascinating species deserving of attention and protection.
Fun Fact: Koalas, with their diet of low-calorie eucalyptus leaves, are champion sleepers, dozing for a whopping 18 hours a day – a lifestyle that’s the envy of many animals.

The Giant Panda, native to centralwestern and southwestern China, stands out not just for its iconic black patches but also for its remarkable hands. Despite being renowned for their perceived laziness, these beautiful creatures possess opposable thumbs, often referred to as false thumbs.
Living in the mountains of central China, Giant Pandas have an extra opposable pseudo thumb on their forepaws. This pseudo thumb, working in tandem with their forefingers, enables precise grasping, particularly useful for capturing small bamboo shoots, which constitute a significant part of their diet.
As of 2014, there were approximately 1864 Giant Pandas left in the wild, a notable increase from around 1000 in the 1970s. Conservation efforts and protected areas in remote regions of central China aim to preserve these unique animals, ensuring the continuation of this captivating species.
Fun Fact: Despite their bamboo-heavy diet, pandas boast the digestive system of a carnivore, a unique trait more commonly associated with their meat-eating counterparts. Nature’s quirky touch in the world of dietary adaptations!
Possums, the marsupials of Australia, exhibit a unique feature in their hands that significantly contributes to their adept lifestyle. With opposable thumbs on both their hands and, interestingly, some on their feet, these creatures are well-equipped for their arboreal existence.
Possums, particularly the widespread Brushtail Possums, are well-adapted to arboreal life. Spending most of their time above ground, their opposable thumbs play a crucial role in climbing trees, grasping branches, and effortlessly navigating their wilderness surroundings.
While the thumbs on their hind feet lack the maneuverability of their hands, possums display remarkable dexterity. They can grasp objects, like human-like hands, making their lives in the wilderness more convenient. Additionally, the presence of a prehensile tail further enhances their ability to cling to tree limbs.
Fun Fact: Possums possess a remarkable immunity to the venom of nearly every snake in their environment, showcasing a unique and impressive adaptation in the animal kingdom.
Often confused with possums, opossums are marsupials found in North America, Mexico, and Central America.
Unlike possums, opossums have opposable thumbs without nails or claws, rendering them non-defensive. However, these thumbs serve them well in climbing trees and sprinting on thin branches. Combined with a prehensile tail, opossums effortlessly navigate arboreal life, making tree-dwelling seem like a breeze.
Opossums, scientifically known as ‘Didelphimorpias,’ are small marsupials found across the Americas, with various species inhabiting different regions. Notably, North America hosts only one species, making it the sole marsupial in the region.
Fun Fact: Opossums, when confronted with danger, instinctively play dead. Interestingly, they have no control over this defensive mechanism, including how long they remain in this seemingly lifeless state.

Waxy Monkey Leaf Frogs
The Waxy Monkey Leaf Frog (Phyllomedusa sauvagii), a recent discovery, stands out as one of the few frog species equipped with opposable thumbs. Also known as Waxy Monkey Tree Frogs, these unique amphibians call South America, specifically Argentina, Bolivia, Paraguay, and Brazil, their home, where they spend the majority of their time in the trees.
While not boasting primate-sized hands, these frogs effectively use their opposable thumbs for grabbing and climbing branches in their arboreal habitat. With a distinctive and otherworldly appearance, they earn their moniker as “monkey frogs.”
These arboreal amphibians lay their eggs on leaves suspended by branches over water sources. This strategic placement ensures that when the eggs hatch, the tadpoles swiftly reach water, facilitating their further development.
Unlike many frog species that use sticky pads on their toes for climbing, the Waxy Monkey Leaf Frog stands alone with its opposable thumb, a remarkable adaptation aiding in grasping twigs and stems while traversing the treetops.
Fun Fact: Monkey Leaf Frogs stand out from the froggy crowd by choosing to walk instead of hopping or jumping, showcasing a distinctive and unusual mode of movement.
Chameleons, renowned for their color-changing prowess, also boast tiny yet mighty hands crucial for navigating branches and diverse terrains. These reptiles possess a unique hand structure with five fingers separated into two bundles: the medial and lateral.
Chameleons employ a distinctive toe arrangement on their feet to expertly grasp twigs and branches as they climb. The “medial bundle” consists of three toes in the middle, while the “lateral bundle” has two toes extending to the side. This arrangement reverses on the rear feet, showcasing the adaptability of their gripping capabilities.
Unlike the anole lizards often seen in pet stores, the chameleons in focus hail from parts of Asia and Africa. While lacking traditional thumbs, their unique toe arrangement on both front and hind feet serves them adeptly in grasping the twigs and branches that make up their arboreal homes.
Fun Fact: Chameleons showcase incredible eye control, moving their eyes separately within a 180-degree field, allowing them to see a full circle around their axis. A remarkable feat in the animal kingdom!
Apes, a diverse group of tailless primates from Africa and Southeast Asia, encompass gorillas, chimpanzees, orangutans, gibbons, and bonobos. What sets them apart is their hands – hands with not only opposable thumbs but also opposable thumbs on their feet.
