For Eating:
* Teeth: Deer have specialized teeth for grinding tough plant material. Their incisors in the front are sharp for nipping off vegetation, while their molars in the back have ridges for crushing and grinding.
* Tongue: Deer have a rough tongue that helps them pull leaves and grass into their mouths.
* Prehensile upper lip: Their upper lip is very flexible, allowing them to grasp and pluck delicate leaves and shoots.
For Survival:
* Eyes: Deer have excellent eyesight, especially in low light conditions. This helps them spot predators and find food.
* Ears: Their large ears are sensitive to sounds, allowing them to detect potential threats from far away.
* Nose: Their sense of smell is incredibly acute. They use it to find food, identify mates, and avoid predators.
* Legs: Deer have strong legs that allow them to run fast and jump high, helping them escape danger.
* Hooves: Their hooves are adapted for running on various terrain and provide traction.
Other interesting facts:
* Deer have a special gland called the "preorbital gland" near their eyes, which secretes a scent used for marking territory and communicating with other deer.
* They also have scent glands on their hooves, which they use to leave their mark on the ground.
While deer don't build homes, they often create "beds" in dense vegetation for resting and hiding from predators. They also create trails through the forest for easy movement and access to food sources.
