Do n’t underestimate thetongue , a mesomorphic organ that humans apply for licking , external respiration , tasting , get down and speaking . But this organ varies wide in color , material body , length and function across the animal land . Whereas human tongue are pink and typically just over 3 inches ( 7.6 centimeters ) long , the anteater has a 2 - animal foot - long ( 60 centimetre ) spit and the spicy - tongued skink has a brilliant blue one .
Here ’s a look at 20 astonishing creature tongues and the science behind them .

Giraffes
If you ’ve ever seen agiraffe’simpressive 21 - column inch - long ( 53 cm ) tongue , you ’ll sleep together that it ’s not pink . Rather , the tall sustenance animal in the earthly concern has a drear - color tongue that looks like a mix of purple , blasphemous and black . That ’s because giraffes ( genusGiraffa ) lingua are covered with a lot of the paint melanin , whichacts as a type of sunblockto protect the licker while it reaches for bid leaves .
Giraffes have such foresightful tongues that they can even utilize them to clean out their ears , according to Mental Floss .
Gila monsters
TheGila monster(Heloderma suspectum ) lives up to the " demon " part of its name with its forked natural language . It ’s think that the gila ’s forked tongue helps it sense in " three dimensions , " meaning that the two tips can find fault up the same smell and then discover the wafting chemical substance gradients in the air , which , in turn , helps the reptilian zero - in on the fix of the smell ’s generator , Andrew Durso , a herpetologist at Florida Gulf Coast University , wrote in The Conversation .
When the vicious lizard gets hungry , it flicks its sore lingua in and out , picking up chemical substance information about its surroundings . Then , the Gila monster’sJacobson ’s organ , a part of the olfactory ( smelling ) system in its nasal chamber , analyse this entropy , permit the lounge lizard make out whether potential prey , such as small mammal , toad , lizard , gnawer and insects , are nearby .
Pangolins
As the only have sex mammal with scales , pangolinsare eldritch beast . Their sticky tongues are just as unknown . The pangolin ’s spit is connected not to the bottom of its mouth , but to the bottom of its ribcage . When it ’s not interfering snatch up up insect , such as ants and termites , the tongue hangs outin the pangolin ’s dresser tooth decay .
When the pangolin ’s tongue is stretch forth , it can measure up to 16 inches ( 40 cm ) long , or longer than the animal ’s head and torso aggregate , according to the BBC .
Sun bears
" The tongue of thesun bear(Helarctos malayanus ) is surprisingly long , measuring up to 10 column inch ( 25 cm ) , agree toGuinness World Records . This feature film helps the bear transfer its inner Winnie the Pooh ; its lengthy tongue can extract honey from hive , a trick that landed it the nickname of " beloved bear,“according to National Geographic .
Hippos
Much of the hippo ’s evolutionary history remains shroud in mystery , grant to National Geographic . Their giant knife are no exception . In a 2010 study published in the journalThe Anatomical Record , researchers look at the tongues of a young and honest-to-god common hippo ( Hippopotamus amphibius amphibius ) with scan electron microscopy and formal light-colored microscopy . ( The 49 - yr - onetime female hippo ’s tongue was 24 inches ( 60 cm ) long , while the 4 - year - sure-enough male ’s was 18 inches ( 45 cm ) long . )
The squad find thathippotongues have features standardised to a few types of animal : odd - toenail ungulates ( such as donkeys , which digest flora cellulose in the intestines , not the stomach ) , ruminants ( such as cattle , which have four - chambered stomachs ) and omnivorous , non - ruminant mammals ( such as pig , which have childlike stomachs ) .
Meanwhile , hippos use their three - chamber tummy to help them digest grass . The animal ’s herbivorous diet and unique evolutionary history may explain " these motley morphologic features of the spit , " the research worker write in the study .
Penguins
Which glossa has more bristles than a hairbrush ? It ’s none other than thepenguin ’s .
The penguin ’s tongue does not have taste bud , but it does have dozens of bristles made out of keratin , the fibrous protein that makes up human hair and nail . These bristles aid the penguin grab wriggly krill and fish , allot to the Smithsonian .
Red-bellied woodpeckers
Woodpecker tongue — made of ivory , cartilage and muscle — need to be really , really long so the birds can nab grub hiding deep in trees . But a pecker ’s backtalk is n’t big enough to house that long tongue . So , what ’s the workaround ? When it ’s not in use , the tongue go into " self storage " by wrapping around the peckerwood ’s skull .
" The cordlike base of the tongue extends back out of their mouth on each side , winding behind and onto the top of their head , sometimes extending so far forward that it hit the nostril,“Larry Witmer , a prof of material body and paleontology with the Department of Biomedical Sciences at Ohio University , told Live Science . " When they postulate to unleash the weapon , the spit basically unwinds from around the head to project into a crevice to becharm its prey . It ’s a remarkable mechanism that ’s develop severally in several kinds of birds , including hummingbird . "

Tongue-eating parasites
This technically is n’t a real knife ; it ’s a sponger that destroy a Pisces ’s spit and then becomes a " substitute " tongue . In other words , this bug - like creature ( Cymothoa Exigua ) is a tongue - eating leech .
After the sponge enters through the fish ’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 leech remains , masquerading as the Pisces ’s new knife .
Lions
Just like other cats , the mightylion(Panthera leo ) uses its tongue to train its pelt . Feline natural language are very efficient combs ; they ’re covered with diminutive spikelet known as papillae , which are sharp , hollow and curved backward toward the big cat ’s throat , according to a 2018 subject in the journalProceedings of the National Academy of Sciences . These pricker help the cat turn in clean saliva to its pelt , which later cool off the cat as it evaporates .
computed axial tomography do n’t handle whether their prey tastes gratifying , however . Their tongue have a useless version of the gene Tas1r2 , which encodes protein that combine to organise lucre - notice sensors on the clapper , National Geographic report .
Giant leaf-tailed geckos
Watch out ! If thegiant leaf - tailed gecko(Uroplatus fimbriatus ) feels threatened , it will verify you do , too . When this gecko is stir up , it opens its jaws astray , flashing its shining red mouth and tongue before it releases a piercing hurt call that sound just like a minor ’s screech , Smithsonian ’s National Zoo reports .
Frogs
Frogsare famous for their fast tongues , and for well reason . More than 4,000 frog species can snaffle objects with their tongue quicker than the human heart can winkle , according to Alexis Noel , a enquiry applied scientist at the Georgia Tech Research Institute who studies frog and cat tongue , antecedently report on her website . She noted that batrachian mouths have a alone anatomy : " Unlike humanity , Gaul tongues are connect at the front of the downhearted jaw , rather than at the back of the throat . "
In increase to its velocity , the anuran lingua is secure . The lingua of the tusk Gaul can root for objects that are about 1.4 times the frog ’s body free weight , a 2014 study in the journalScientific Reportsfound .
Blue-tongued skinks
Blue - tongued skinks , natives of Australia and New Guinea , use their vivacious low tongue to startle predators , according to the San Diego Zoo . When threatened , the scincid lizard puffs up its body so that it appears larger , open up its oral fissure and hisses while it sticks out its tongue .
Eagles
Eagleshave tongues with backward - facing barbs called " rear - organize papillae , " which help them immerse quarry , 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 fertilise their young , they use their tongues to help keep away declamatory bone , furred clod and sharp fin that could cause the doll to choke , according to the Raptor Resource Project , a nonprofit bird group based in Iowa .
Alligator snapping turtles
Thealligator - snap turtle(Macrochelys temminckii ) has a ingenious trick ; it utilise its little pinkish knife as a fishing lure . While these turtles are known to forage for food along the bottoms of rivers , lakes and swamps , they can also lie still with their mouths open and tongue wriggling , as they hold back to ambush fish that err their tongues for worms , according to the Nonindigenous Aquatic Species program of theU.S. Geological Survey .
Parrots
How doparrotsand parroket ( a type of parrot ) mimic human speech ? It turns out that Polly can adjust her nimble , brawny knife so that it regulate the audio coming from her voice box , allot to Science magazine . In one small experiment , repositioning the glossa of five dead monk parakeets ( Myiopsitta monachus ) , whose outspoken piece of land were connect to speaker systems , lead to changes in pitch and loudness , which is key for work vowel in language , according to a 2004 study in the journalCurrent Biology .
Emperor tamarins
While humans might take line of the emperor leoncita ’s distinctive moustache , its fellow emperor tamarins ( Saguinus imperator ) may have their heart on something else : the tongue . When these high priest are displeased , they tend to flip their tongues , quickly displace the tongue in and out of the back talk , according to Apenheul Primate Park , a zoological garden in the Netherlands . The emperor tamarin also intercommunicate with sharp birdsong , chirps , hiss and facial expressions , which , blend with tongue flicking , help keep its flock together and alarm to danger , allot to theNew England Primate Conservancy .
Flies
That hairy appendage dangling out of a fly front ’s mouth may look like a knife , but it ’s not . scientist call it the labellum , and it ’s the primary gustatory sensation organ for theDrosophilafruit rainfly , according to a report from Indiana Public Media . The labellum is attached to the rainfly ’s shuck - like proboscis , which allows the pest to slurp up food . A intelligence to the wise : Put your leftovers out if you ’ve got a fly problem . These buzzing beasties puke saliva and digestive juices onto nutrient before eat it , because these acids fade out the nutrient the fly wants to suck up , according to HowStuffWorks .
Giant anteater
The giant Orycteropus afer ( Myrmecophaga tridactyla ) does n’t have teeth , but it does n’t need them ; instead , it use its close to 2 - foot - long ( 60 cm ) tongue to exhaust up to 30,000 ants and termites a day , according to the San Diego Zoo . This narrow and spaghetti - same clapper , which is attached to the mammalian ’s sternum , is covered with bantam , backward - steer spikelet and sticky spit to help it grab the tiny insects . The anteater ’s tongue is fast , too — it can dart in and out of its lip up to 150 time a minute .
Chameleons
Chameleonsare relatively deadening fauna , but their 20 - in - long ( 50 cm ) tongue are fast enough to catch rapid insects , such as locusts , mantid and grasshopper . The tip of the Chamaeleon ’s knife is a ball of muscle , and once it hits prey , that clump transforms into a sucking cupful . The instant the quarry is stuck , the reptile draws its tongue back into its lip , where its strong jaws crush the snap , accord to the San Diego Zoo .
Hummingbirds
Hummingbird tongues were misunderstood for more than 180 long time , until a 2015 cogitation set the record heterosexual . Initially , scientists retrieve that hummingbird tongue used capillary activity — in which liquid state can flow through narrow-minded TV channel , even againstgravity — to pull up floral ambrosia . But really , thesetongues act as elastic micropumps , accord to the journalProceedings of the Royal Society B : Biological Sciences .
High - focal ratio videos showed that the hummingbird flattens the tip of its outstretched tongue against a worthy peak , then remold its tongue so it can fill with nectar . Next , the top of the tongue ( the part by the sass ) bends , which produces flexible Department of Energy that can pull out the nectar out of the flower . This cognitive operation lets the bird slurp up its food at fast fastness , the study found .
