The Anteater's Tongue Is an Evolutionary Masterpiece. Anteaters are very good animals. They somehow pull off the whole “slurp up ants with their sticky, noodly, bendy straw tongues” so confidently you forget how weird that is. And scientists agree that, yes, anteater tongues are weird. But they’re also understudied. A team of Brazilian researchers is therefore spending its time trying to understand these slimy ant- licking noodlemouths. How did anteaters end up with such silly appendages, while their close relatives like sloths and armadillos feature, well, more normal tongues?

The answer is, of course, evolutionary adaptations to their ant- filled diets.“All musculature involved in . Google Chrome Beta 14 0 835 159 Bus. We think the selective pressures in this diet led to a gradual stretching of the tongue.”A stretching of the tongue whose incredible results look like this: The author’s latest study involved sampling 2. After examining the tongues in various ways and under a microscope, they observed an oval- shaped cross section of a long, narrow tongue. The part furthest from the skull was covered in bumpy protrusions, and the front part was rounded and smooth.

The southern tamandua and the giant anteater’s tongues had conical tips that made them look like, well, penises (the silky anteater did not). On top of that, the muscular structure of the tongue implied that it probably stretches a lot, according to the paper published recently in the Journal of Morphology. This suggests that the muscles are specifically designed to maximize the organ’s speed and stretchiness to fit the feeding behavior. And of course, the whole thing is covered in sticky mucous. But there aren’t a lot of taste buds, as observed in this and in past studies—after all, anteaters are mainly eating ants and, accidentally, dirt.

In fact, the whole animal seems to be adapted for its bug- eating purpose, ripping up ant nests with its strong arms, punching holes with its claws, and sticking its spaghetti tongue into the holes it made. The tongue even has horns that can help grab ants and termites while the anteater explores nests. Casali also pointed out that the distantly related pangolin evolved a completely different tongue of the same shape. They achieve the same end product through different pathways.”Anyway, enjoy the miracle evolution has wrought to create such well- tuned, silly looking spaghetti- mouthed noodleheads.
