A girl who used to be in my school had a medical case where her tongue was more or less attached to the floor of her mouth. The membrane was either too short or too rigid. But the doctors made her have it surgically removed because she couldn't speak clearly otherwise. I guess it allows your tongue to move around your mouth properly.
They have to have flexible tongues to reach the leaves on top of a tall tree. And also to pick their boogers too. Gross rite? i hope this helps
crocodile (Not true, their tongues aren't free but held in place by a membrane which limits movement; however they can't stick out their tongues.)
Giraffes use their flexible lips and long tongues to pluck leaves. Then they use their teeth to chew up the leaves. Chewing is an important part of digestion for most herbivorous mammals.
The belief is giraffes developed long necks and long tongues so they could feed on vegetation higher up than other animals and therefore had a survival advantage.
Only some do. The giraffe is the best example. It needs this so it can reach its' food.
Humans are capable of speech because they have flexible tongues and vocal cords. A part of the cerebral cortex also helps control speech.
Frogs have very flexible tongues and they are very sticky, so when a bug goes by they just extend their tongue and it will catch the bug and they will eat it .
This allows them to forage from treetops that are inaccessible to other herbivores. Their diet mainly consists of tender leaves and shoots.
No, alligators, like crocodiles, cannot stick their tongues out. This is because there is a membrane that attaches the tongue to the floor of their oral cavity.
Walrus' do not have tongues
They smell with their tongues
