Crocodiles cannot stick their tongue out of their mouth because it is attached to the bottom of their mouth by a membrane. This adaptation helps them to prevent water from entering their throat when they are submerged.
Camera traps are one means that scientists use to do this.
you pull it out hard
they have large covere with hard sharp bones
you could have bitten it really hard!
If you apply more pressure with your tongue it will, it doesn't usually simply because the tongue is a soft muscle, but your teeth are hard.
ok, if its hard around the Piercing that's normal, its a callus forming, but if your whole tongue is hard, then I'm not for sure why that is, only thing i can think of is the swelling.
no you dont beacause blue tongue lizards cant bite hard
If you have a tongue ring, it makes it hard to make out. the ring always gets in the way.
I have had my tongue ring for almost 10 years, and I have a small hard spot close to the tongue ring. I think it is just the tongues version of scar tissue. It hardens up to protect itself from the tongue ring being there. And I even have a round indention on the top of my tongue from the ball pushing down for so long. Hope this helps you!
Some people believe that the giraffe's tongue is blue or purple in color so that they do not get sunburned from feeding all day. The long tongue, which can be extended almost 20 inches is helpful to pluck food down from hard to reach places. It has also been said, that the tongue is blue/black/purple in color because it has very few blood vessels. This means that the surface tissue of the tongue will have a darker pigment associated with it (the blue/black tone). The lack of blood vessels makes the giraffe's tongue tougher then most other animals. This helps them to feed on trees and resist impact from sharp thorns such as the ones found on the Acacia trees that they feed on.
