When they find some insects, they rip open the insect s nest and use their long, sticky tongue to scoop the food into their mouth. When full-grown, aardvarks are about six feet long. They have a small amount of stiff, brown or gray hair all over their bodies, and their heads are pig-like, except their snout is longer and heavier. Snout is another word for nose. They can close their nostrils.
Aardvarks have big ears and short necks.
They have very soft teeth, without hard enamel, and are the only mammal with teeth that have no roots. Their teeth are perfect for crushing insects. The aardvark communicates with barking and grunting sounds. To call their babies, they often bark in a high-pitch. Aardvarks are very gentle animals.
