Hide and Seek for Survival
In the wild, it es down to predator and prey,
the hunter and the hunted. As you can imagine, anisms want to stay alive.
They have developed ways of adapting to severe habitats, and hiding or escaping
from those who would like to eat them. So how do they do it?
One very helpful adaptation is called camouflage. You may have been
surprised by an animal that was using camouflage in the past. It blended into its
surroundings so well that you nearly missed seeing it at all. Its coloring, markings
, or other physical features resemble its habitat so much that you can look
directly at it without seeing it at first.
This is often good enough to fool a predator that is scanning an
area to look for food. This helps prey to hide from its predator. But did you know
that it often works the other way around, too? Predators can use camouflage to
trap their prey.
If a predator wants to eat a certain animal, and that animal
cannot see it lying in wait, it can jump on its prey unexpectedly, devouring it
before it even knows what is happening. Another popular adaptation is mimicry.
Mimicry is when an animal has markings or other physical characteristics that
allow it to look like some other kind of animal or plant. If it can make its predators
believe that it is something that preys on them, or would at least be difficult or
painful to catch, its predator will often go off in search of an easier target.
Sometimes animals are able to survive when their habitat
changes because they adapt to the new conditions. For example, birds that were
accustomed to nesting on high cliffs or in tall trees have survived changes of their
habitat by learning to nest in the crevices of tall buildings. oons easily adapt
to residential areas that have taken over their woodland homes. They often help
themselves to any food they can grab, whether it is in trashcans, or inside people’s
homes!
