Protection from
Predators
Animals are always in danger of being eaten and have developed many
methods of protecting themselves from hungry animals.
- Hiding: Some animals simply hide from
predators, concealing themselves in burrows, under rocks or
leaves, in tree hollows, or in other niches where they are hard to
find.
- Camouflage: Camouflage is another way
of hiding, in which the animal blends into its environment. Many
animals, like the "walking stick" insect and the Indian Leaf
Butterfly (Kallima inachus) are camouflaged so well that they are
virtually invisible when they are standing still. Sloths are
covered with a greenish layer of algae which camouflages their fur
in their arboreal environment. Sloths also move very slowly,
making them even harder to spot.
- Scaring predators: Some animals try to
convince predators that they are bigger and more fierce than they
really are. For example, the larva of the lobster moth (Stauropus
fagi) looks like a scorpion, but is in fact completely
defenseless. Many butterflies have large "eye" designs on their
wings. This makes them look like the head of a very large animal
instead of a harmless butterfly, and scares many predators
away.
- Warning colors: Poisonous animals
openly advertise their defense methods, usually with bright colors
and flashy patterns. When a predator eats one member of the group,
it will get sick. This
memory will stay with the predator, who will avoid that type of
animal in the future. This method sacrifices a few individuals in
order to protect the entire group. Examples of poisonous animals
include the Monarch butterfly and the Queen Alexandra's Birdwing
Butterfly. Other animals (poisonous or not) have come to mimic
poisonous butterflies, obtaining the benefits of their poisonous
"twins." This is called mimicry.
- Running away: Fast animals can try to
run from predators.
- Attacking: Some animals are equipped
with sharp teeth, claws and/or horns that can be used to repel
predators.
