Do n’t underestimate thetongue , a hefty pipe organ that humans use for licking , external respiration , savouring , get down and speak . But this organ depart widely in color , Supreme Headquarters Allied Powers Europe , distance and function across the animal kingdom . Whereas human tongues are pinkish and typically just over 3 inches ( 7.6 centimeters ) long , the New World anteater has a 2 - foot - long ( 60 cm ) clapper and the low - tongued scincid lizard has a brilliant blue one .
Here ’s a flavor at 20 amazing animal tongues and the science behind them .

Giraffes
If you ’ve ever seen agiraffe’simpressive 21 - inch - farseeing ( 53 cm ) knife , you ’ll know that it ’s not pink . Rather , the tall aliveness animal in the world has a sour - colored tongue that looks like a mix of over-embellished , drear and disgraceful . That ’s because Giraffa camelopardalis ( genusGiraffa ) tongues are covered with a lot of the paint melanin , whichacts as a type of sunblockto protect the licker while it reaches for attender leaves .
Giraffes have such foresighted knife that they can even use them to make clean out their ear , consort to Mental Floss .
Gila monsters
TheGila monster(Heloderma suspectum ) live up to the " monster " part of its name with its forked tongue . It ’s thought that the gila ’s fork knife helps it smell in " three dimensions , " meaning that the two tips can beak up the same odor and then make out the waft chemical substance gradients in the gentle wind , which , in good turn , helps the reptilian zero - in on the location of the smell ’s source , Andrew Durso , a herpetologist at Florida Gulf Coast University , wrote in The Conversation .
When the deadly lizard gets athirst , it flicks its tender lingua in and out , picking up chemical information about its environment . Then , the Gila monster’sJacobson ’s organ , a part of the olfactory ( smell ) system in its nasal chamber , analyzes this selective information , rent the lizard know whether potential prey , such as small mammals , frogs , lizards , rodents and insects , are nearby .
Pangolins
As the only known mammal with scales , pangolinsare weird creatures . Their pasty tongues are just as foreign . The pangolin ’s tongue is link up not to the bottom of its lip , but to the bottom of its ribcage . When it ’s not busy snatching up insects , such as ants and termites , the knife hangs outin the scaly anteater ’s breast tooth decay .
When the anteater ’s clapper is stretch , it can measure out up to 16 inches ( 40 atomic number 96 ) long , or longer than the animal ’s header and body flux , consort to the BBC .
Sun bears
" The tongue of thesun bear(Helarctos malayanus ) is surprisingly long , measure up to 10 column inch ( 25 cm ) , according toGuinness World Records . This feature helps the bear channel its privileged Winnie the Pooh ; its lengthy tongue can extract honey from beehive , a trick that bring down it the nickname of " honey bear,“according to National Geographic .
Hippos
Much of the hippo ’s evolutionary history remains shroud in mystery , according to National Geographic . Their jumbo tongues are no exclusion . In a 2010 subject field publish in the journalThe Anatomical Record , researchers looked at the lingua of a young and old vulgar hippopotamus ( Hippopotamus amphibius amphibius ) with scanning electron microscopy and conventional calorie-free microscopy . ( The 49 - year - honest-to-god female hippo ’s tongue was 24 inches ( 60 centimeter ) long , while the 4 - year - quondam male person ’s was 18 inches ( 45 cm ) long . )
The squad found thathippotongues have features like to a few types of animals : odd - toed ungulates ( such as donkeys , which digest industrial plant cellulose in the gut , not the stomach ) , ruminants ( such as oxen , which have four - chambered stomach ) and omnivorous , non - ruminant mammalian ( such as pig , which have uncomplicated tummy ) .
Meanwhile , hippos use their three - chambered stomachs to avail them digest forage . The animal ’s herbivorous diet and unique evolutionary history may explain " these motley morphological features of the tongue , " the research worker write in the subject area .
Penguins
Which tongue has more bristle than a hairbrush ? It ’s none other than thepenguin ’s .
The penguin ’s clapper does not have taste buds , but it does have stacks of bristles made out of keratin , the fibrous protein that makes up human hair and nails . These bristle help the penguin grab wriggly krill and fish , harmonize to the Smithsonian .
Red-bellied woodpeckers
Woodpecker tongues — made of ivory , cartilage and muscularity — need to be really , really long so the birds can nab grubs hiding deep in trees . But a woodpecker ’s backtalk is n’t big enough to house that longsighted tongue . So , what ’s the workaround ? When it ’s not in use , the tongue break down into " self depot " by enwrap around the woodpecker ’s skull .
" The cordlike home of the natural language extends back out of their mouth on each side , winding behind and onto the top of their fountainhead , sometimes extending so far forward that it reaches the nostril,“Larry Witmer , a professor of anatomy and paleontology with the Department of Biomedical Sciences at Ohio University , told Live Science . " When they necessitate to let loose the weapon , the tongue basically unwinds from around the head to throw into a cranny to capture its prey . It ’s a remarkable mechanism that ’s evolved independently in several variety of birds , including hummingbird . "

Tongue-eating parasites
This technically is n’t a real tongue ; it ’s a sponger that put down a Pisces ’s clapper and then becomes a " substitute " tongue . In other word , this bug - like creature ( Cymothoa Exigua ) is a tongue - deplete parasite .
After the parasite enters through the Pisces ’s gill , it latches onto the tongue with its seven pairs of legs and ( brace yourself ) begin to feed on the tongue like a vampire . Soon , the tongue withers and drops off , but the parasite stay , masquerade as the Pisces ’s novel tongue .
Lions
Just like other cats , the mightylion(Panthera leo ) uses its tongue to groom its fur . Feline tongues are very in force combs ; they ’re covered with tiny spines know as papilla , which are sharp , vacuous and trend rearwards toward the African tea ’s throat , according to a 2018 field in the journalProceedings of the National Academy of Sciences . These spines facilitate the cat turn in cleansing spit to its fur , which afterwards cool down the cat as it evaporates .
khat do n’t like whether their prey tastes sweet , however . Their tongue have a useless variant of the gene Tas1r2 , which encodes proteins that combine to form sugar - detecting sensor on the tongue , National Geographic reported .
Giant leaf-tailed geckos
Watch out ! If thegiant foliage - tail gecko(Uroplatus fimbriatus ) feels threatened , it will check that you do , too . When this gecko is disturbed , it opens its jaws astray , flashing its bright red oral fissure and knife before it releases a piercing suffering call that sound just like a child ’s shriek , Smithsonian ’s National Zoo reports .
Frogs
Frogsare famous for their fast spit , and for salutary reason . More than 4,000 toad metal money can snaffle objects with their glossa faster than the human eye can blink , according to Alexis Noel , a research locomotive engineer at the Georgia Tech Research Institute who analyze frog and true cat tongues , previously account on her internet site . She take down that Gaul mouths have a unique anatomy : " Unlike humans , batrachian tongues are connected at the front of the lower jaw , rather than at the back of the pharynx . "
In addition to its upper , the frog tongue is strong . The tongue of the horned salientian can pull objects that are about 1.4 time the frog ’s body weighting , a 2014 study in the journalScientific Reportsfound .
Blue-tongued skinks
Blue - tongued skinks , natives of Australia and New Guinea , utilize their vibrant blue tongue to galvanise predators , harmonize to the San Diego Zoo . When threatened , the scincid puffs up its consistence so that it appear turgid , open its mouth and hisses while it sticks out its tongue .
Eagles
Eagleshave tongues with back - confront barbs called " rear - directed papillae , " which serve them swallow prey , according to the Center for Conservation Biology , a research group at the College of William and Mary and the Virginia Commonwealth University . When bird of Jove parent are feeding their untried , they use their tongue to help keep away large bones , furry glob and penetrating fins that could cause the chicks to choke , harmonise to the Raptor Resource Project , a nonprofit bird group based in Iowa .
Alligator snapping turtles
Thealligator - snap turtle(Macrochelys temminckii ) has a clever conjuring trick ; it uses its little pink tongue as a fishing lure . While these turtle are known to forage for food along the derriere of river , lakes and swamps , they can also lie still with their mouths open and tongue wriggling , as they await to still-hunt fish that mistake their tongue for worm , grant to the Nonindigenous Aquatic Species plan of theU.S. Geological Survey .
Parrots
How doparrotsand parakeets ( a type of parrot ) mimic human speech ? It change by reversal out that Polly can adjust her nimble , muscular tongue so that it modulate the sound come from her voice boxful , according to Science mag . In one small experimentation , repositioning the tongue of five beat monk parakeets ( Myiopsitta monachus ) , whose vocal pamphlet were link up to loudspeaker systems , leave to changes in pitch and loudness , which is key for forming vowels in language , accord to a 2004 study in the journalCurrent Biology .
Emperor tamarins
While man might take note of the emperor moth lion monkey ’s typical mustache , its fellow emperor moth leoncita ( Saguinus imperator ) may have their optic on something else : the tongue . When these primates are displeased , they incline to thumb their tongues , quickly move the natural language in and out of the oral cavity , harmonise to Apenheul Primate Park , a menagerie in the Netherlands . The emperor tamarin also communicate with sharp calls , chirps , hiss and facial expressions , which , combine with lingua flicking , help keep its troop together and alert to danger , agree to theNew England Primate Conservancy .
Flies
That haired appendage dangle out of a fly ’s mouth may wait like a tongue , but it ’s not . Scientists call it the labellum , and it ’s the primary taste organ for theDrosophilafruit fly , accord to a report from Indiana Public Media . The labellum is attached to the fly ’s wheat - like proboscis , which allows the pest to slurp up food . A Son to the wise : Put your leftovers away if you ’ve have a fly problem . These buzzing beasties puke saliva and digestive juices onto food for thought before corrode it , because these acids dissolve the food the fly wants to suck up , according to HowStuffWorks .
Giant anteater
The giant anteater ( Myrmecophaga tridactyla ) does n’t have teeth , but it does n’t need them ; instead , it uses its roughly 2 - foot - long ( 60 cm ) tongue to eat up to 30,000 emmet and termites a day , grant to the San Diego Zoo . This narrow and spaghetti - similar glossa , which is attached to the mammal ’s breastbone , is covered with tiny , backward - pointing backbone and unenviable spittle to help it catch the bantam insect . The New World anteater ’s tongue is fast , too — it can fleet in and out of its mouthpiece up to 150 times a minute .
Chameleons
Chameleonsare relatively dull creatures , but their 20 - inch - long ( 50 atomic number 96 ) tongues are fast enough to catch speedy worm , such as locust tree , mantid and grasshopper . The wind of the chameleon ’s natural language is a chunk of brawniness , and once it hits prey , that lump transmute into a sucking cup . The minute the prey is stuck , the reptile make its tongue back into its mouth , where its stiff jaws crush the catch , according to the San Diego Zoo .
Hummingbirds
Hummingbird tongues were misunderstood for more than 180 twelvemonth , until a 2015 study set the record straight person . Initially , scientists thought that hummingbird tongue used capillary activity — in which liquid can flow through minute transmission channel , even againstgravity — to pull up floral ambrosia . But really , thesetongues act as elastic micropumps , agree to the journalProceedings of the Royal Society B : Biological Sciences .
High - speed video showed that the hummingbird flattens the tip of its outstretched tongue against a desirable blossom , then reshapes its lingua so it can fill with nectar . Next , the top of the lingua ( the part by the mouth ) crook , which produces elastic DOE that can draw the nectar out of the flower . This process have the bird slurp up its solid food at truehearted speeds , the written report institute .
