What are in hot or dry environments?

In hot or dry places, plants and animals have special body covers that act like tiny umbrellas or sweaters to keep them safe from the sun and water loss.

The Skin Covering

Imagine you just took a shower. Your skin feels smooth because of a natural oil that keeps moisture in. Plants in deserts have something similar called a cuticle. It is a waxy, shiny layer on top of their leaves or stems. This layer stops water from evaporating into the dry air, much like how food wrap keeps your sandwich from drying out in the backpack. Without this wax, a cactus would turn into a raisin before sunset!

Special Shapes

Many desert plants store water inside thick stems, like a succulent. Aloe vera is a great example. Its juicy leaves are like little water bottles packed full of liquid. Animals also adapt by having large ears to let out heat or light fur that reflects sunlight.

Think of a cactus as a camel that carries its own water supply and wears a shiny jacket.

These adaptations help living things stay cool and hydrated when the sun is blazing and the air is crisp and dry.
