ADAPTATION OF THE ANTEATER

The giant anteaters are animals found in Central and South America, more exactly in areas of grasslands, deciduous forests and rainforests. They feed mainly on ants and termites, sometimes up to 30,000 insects in a single day!

They main characteristics of adaptation are:

  • They have a very keen sense of smell used to located ants.
  • They have poor sight, because they commonly are nocturnal
  • They have claws in each foot, in order to used them to break open ant and termite mounds for feed, as well as use for a effective defence from predators.
  • The anteater walks on its knuckles in order to protect them, giving it a shuffling gait.
  • The anteater’s tongue can reach 60 cm in length and it have sticky for help them to  feed. Their long muzzle without teeth inside also help them to feed.
  • They tail is use to aid balance when they are threatened and have to stand up on its hind legs.

If you want to read more about this animal, I post here the webs in which I have found the information and the photographs:

Weekend homework about natural selection

Some animals are better suited to their enviroment than others. These ones normally are more likely to survive in their environment.

Talking about anteaters for example, we can start saying that anteaters usually bear a single offspring after a gestation period of 190. They don’t have a lot of offspring, however they produce a number of offspring that is finally reduce because of a predator ( jaguars in this case). This is called over-production. On anteaters exist a considerable regional variation, the ones who live near civilization used to be nocturnal and are almost blind, however the wildest ones are diurnal and usually eat with the day light, they develop the sense of smell to much. These adaptation as well as others are passed into the offspring in order to create new species which are going to be more able to win the struggle for existence. In place near civilizations only the nocturnal anteaters survive, the rest died because haven’t been well adapted to the environment, this idea lead also us to the survival of the fittest, where only the best adapted continued living without a high level of danger and finally to natural selection.
