Other animals imitate the shapes, smell, tastes, color, or even the size of other
animals. This behavior is called mimicry.

Most insects secrete chemicals that they use to protect themselves like squid,

wasp, and snake. Other animals protect their own kind. Mosquitoes, elephant, and

penguins travel through the jungle in family groups. They scatter themselves to look
for food but they do not go far from one another. They stay within hearing distance.

When there is danger, they group together. They protect each other.

Not all animals (prey) can move fast so it would be difficult for them to run
