Grazing animals such as deer and cattle have very long tongues, which help them to manipulate vegetation while feeding. Perhaps you have seen photographs of deer feeding on the leaves of trees, curling their tongues round the twigs, or watched grazing cattle sweeping the grass into clumps before they bite. Our tongues are much shorter, and while we have to make an effort to stick them out, deer have to hold their tongues in ! When they die, their tongues simply fall out, they do not need to stick them out. When an animal has been dead for a while, and has begun to decompose, the tongue may swell, causing it to protrude.
