  • Natural Range - Aardvarks are mainly found in sub-Saharan Africa
  • Diet - An Aardvarks diet an range from eating mostly termites in the wet season, to eating mainly ants, seeds, insect larvae, and some fruits in the dry season
  • Habitat - Aardvarks mainly live on grasslands and savannas

  • Lifespan - About 10 years

Physical Adaptations

Aardvarks have sharp, spade like claws which they use to dig. This is helpful for them to be able to dig into the earth with great speeds which allows them to hunt, and escape predators more easily. Aardvarks also have very sensitive ears that move independently, this helps them hear the sound of ants digging so they can locate them, they can also use this adaptation to hear predators while they are distracted. Another adaptation used to help them hunt is a very sense of smell which also helps them locate ant or termite colonies. Yet another adaptation used to help them hunt is their sticky tongue similar to an ant eaters used to catch many ants or termites to eat. How they do is they bend down and slither their long tongue into the colony can there many ants are caught. Another adaptation is they have thick skin, this helps because this way they don't get effected by bites or stings from insects. Aardvarks along with their claws for digging also have strong, muscular legs to dig through dirt. Since Aardvarks travel mainly at night, they have many rods in their eyes which allow them to see very well at night or in the dark. Finally, they have a long, slender(skinny) snout so they can further put their face toward the ground to swoop up ants.

Behavioral Adaptations

Aardvarks are nocturnal which means travel at night, this way they can avoid predators like lions and cheetah who usually sleep during the night. To conserve food, Aardvarks don't completely destroy ant or termite colonies when hunting, allowing it to be rebuilt, this way Aardvarks can always come back for more ants. To avoid being eaten, when near predators, Aardvarks try to burrow deep into the ground to escape, if they can't escape, then they stand on their hind legs and swipe their claws repeatedly at their enemies. Since Aardvarks populations are low, males tend to go around and mate with as many females as possible, so then they can produce many offspring. Since an Aardvark's predators mostly travel at day, Aardvarks when they do travel at day (which is rare), they try to stay near tall grass to conceal themselves. Finally, Aardvarks dig into earth and create shelter called burrows, which is how they got their name, Aardvark really means "earth-pig". This burrow acts as shelter and defense.
