Long tongues serve many purposes in the animal kingdom, from catching prey to gathering nectar. Some of the world’s most fascinating species rely on their elongated tongues to survive and thrive in their environments.
This list showcases 16 animals known for their impressive tongues, with interesting facts and photos for each. Whether you’re curious about mammals, reptiles, or birds, you’ll find some surprising contenders here.
Mammals with Remarkably Long Tongues
Giant Anteater
The giant anteater’s tongue can reach up to 2 feet (60 cm) long-far longer than its own head. This sticky, flexible tongue flicks in and out of anthills up to 160 times per minute, scooping up ants and termites. Its tongue is coated with saliva and covered in backward-facing spines that help trap insects.
Giraffe
A giraffe’s prehensile tongue measures about 18-20 inches (45-50 cm). It’s dark blue to protect against sunburn and strong enough to strip leaves from thorny acacia trees. Giraffes use their tongues like hands to grab food high in the trees that few other herbivores can reach.
Pangolin
Pangolins, scaly insectivores found in Asia and Africa, have tongues that can exceed the length of their bodies when fully extended. Their tongues aren’t attached to the mouth floor but to the chest, allowing them to probe deep into termite tunnels. The tongue’s sticky coating helps them slurp up thousands of insects per night.
Surprising Long-Tongued Birds
Hummingbird
Hummingbirds have tongues that are roughly twice as long as their beaks. Their tongues are split, forming two tubes that pump nectar through capillary action. The tongue flicks in and out up to 20 times per second, allowing them to feed on flower nectar efficiently.
Woodpecker
Woodpeckers, such as the Northern Flicker, have tongues that can stretch up to 4 inches (10 cm)-often longer than their beaks and even their heads. The tongue wraps around the skull when retracted and is tipped with a barbed end for extracting insects from tree bark.
Honeycreeper
The Hawaiian honeycreeper’s tongue is long and tubular, designed for reaching deep into flowers to gather nectar. Their specialized feeding technique allows them to access food sources that other birds cannot.
Reptiles with Notable Tongues
Chameleon
The chameleon’s tongue can be up to twice the length of its body. When hunting, it shoots its tongue out at lightning speed (up to 13 mph), striking insects in a fraction of a second. The sticky tip grasps prey with incredible accuracy. The tongue is powered by specialized muscles and a unique bone called the entoglossal process.
Blue-tongued Skink
While not the longest, the blue-tongued skink’s tongue is still impressive. Its broad, bright blue tongue is used as a defense mechanism to startle predators and signal that the skink is not an easy meal. The tongue can extend well outside the mouth in display.
Amphibians with Elastic, Fast-Moving Tongues
Frog
Many frog species have tongues that can stretch to twice their body length. The tongue is anchored at the front of the mouth, allowing it to flip out rapidly to catch insects. The tip is sticky and coated with mucus, ensuring prey sticks as the tongue snaps back. Examples include the common toad and the American bullfrog.
Salamander
Some salamanders, like the lungless plethodontid family, have projectile tongues that can reach up to 80% of their body length. These amphibians rely on their ballistic tongues to grab prey with remarkable speed and accuracy, especially in humid forest environments where insects abound.
Unusual Insect Tongues
Butterfly
Butterflies and moths have a proboscis, a tube-like tongue that uncoils to reach nectar deep within flowers. The proboscis can be longer than the butterfly's body in species like the Morgan’s sphinx moth, whose tongue can reach over 11 inches (28 cm). This adaptation allows them to feed from flowers that are inaccessible to other pollinators.
Hawk Moth
Hawk moths, another group of long-tongued insects, are famous for their hovering flight and extremely long proboscises. The Madagascan sphinx moth (Xanthopan morganii) was predicted by Darwin to have a tongue long enough (up to 12 inches) to reach the nectar of the star orchid. This was confirmed decades later when the moth was discovered with its coiled tongue matching the plant’s nectar spur.
Fish and Marsupials with Amazing Tongues
Tube-lipped Nectar Bat
Found in Ecuador, the tube-lipped nectar bat has the longest tongue relative to its body of any mammal. Its tongue can stretch 1.5 times its body length-over 3.3 inches (8.5 cm)-allowing it to reach deep into flowers for nectar. The tongue retracts into the bat’s rib cage when not in use.
Okapi
The okapi, a relative of the giraffe from the Congo, has a tongue that reaches about 18 inches (45 cm). Its tongue is prehensile, helping the okapi strip leaves and clean its own eyes and ears. The dark color also protects against sunburn.
Lingcod
The lingcod is a fish native to the North American Pacific coast. It has a large, muscular tongue covered in small teeth-like projections called 'odontodes,' which help it grip slippery prey. While not the longest tongue, it’s notable for its function and appearance in the fish world.
Primates and Pets with Noteworthy Tongues
Sun Bear
The sun bear, native to Southeast Asia, has a long tongue-up to 10 inches (25 cm)-which it uses to extract honey from beehives and insects from tree crevices. The tongue’s length and flexibility make the sun bear an expert at raiding nests and gathering food that other bears can’t reach.
Dog
Domestic dogs may not have tongues as long as anteaters, but some breeds, like St. Bernards and bloodhounds, have notably long, floppy tongues. Dogs use their tongues for cooling, grooming, and social communication. Some dogs, due to genetics or injury, have tongues that hang out more than usual. The Guinness World Record for the longest dog tongue belongs to a St. Bernard named Mochi, whose tongue measured over 7 inches (18.5 cm).
Spider Monkey
Spider monkeys have long, flexible tongues that help them manipulate fruit and leaves in treetops. Their tongues, combined with agile limbs and a prehensile tail, are part of their adaptation to a diet rich in soft plant material and occasional insects.
Frequently asked questions
Which animal has the longest tongue relative to its body?
The tube-lipped nectar bat holds the record, with a tongue 1.5 times its body length.
Why do some animals have such long tongues?
Long tongues help animals access food sources that are otherwise hard to reach, such as insects deep in tunnels, nectar in long flowers, or leaves among thorny branches.
Are there any pets with unusually long tongues?
Yes. Some dog breeds, particularly St. Bernards and bloodhounds, can have remarkably long tongues, sometimes due to genetics or injury. Cats, while not as extreme, also use their tongues for grooming and feeding.
Do all animals with long tongues use them for eating?
Mostly, yes, but some also use their tongues for grooming, defense, or communication, depending on the species.
