Preorbital gland

So, you know how some animals have different ways of communicating with each other? Like dogs bark or wag their tail to show their feelings? Well, some animals have a special type of gland near their eyes called a preorbital gland that helps them communicate.

This gland produces a scent, kind of like perfume, that animals use to mark their territory or communicate with other animals. For example, deer might rub their face onto a tree or other objects, leaving their scent from their preorbital gland behind. Other deer can smell that scent and know that this is the territory of that particular deer.

Some animals also use their preorbital gland to show their feelings, like if they are feeling scared or excited. These scents can help other animals know what emotions they might be feeling.

Overall, the preorbital gland is just a special gland that animals use to communicate with other animals through scent.
