Sometimes under the ground depending on the animal or desert.
The barrel cactus can be a plant that animals can get water from in the desert.
Cactus
cactus has water for animals and it is a home for most desert creatures
They get water from the fluids of other animals, eating plants aka/ drinking the moisture on the plants aka cactus, or if there is rain.
The cactus is one of the few plants found in the desert, and in order to survive it needs a massive amount of water. Since it does not rain all year round in a desert, cacti store water when it does rain. So the needles on the cactus protect their water-rich flesh from other things in the desert.
A cactus competes with other plants for water.

You can find water in cactus.
animals like lizards and some bugs live in their. usually animals who don't drink water. if they do drink water they open cactus's and eat each other or their prey.
Cactus remain in the desert because they can survive in harsh environments. Cactus plants have the ability to collect all the water they can get, and store it inside them for months on end. The "thorns" or "pricks" of the cactus, protect the plant from animals who might want to eat it.Cactus is formed in the desert due to scarecity of water, high temperature and less organic matter in the soil.
If you're referring to their water sources, you're right by inferring that they cannot simply drink water as animals in a jungle can. Instead, they get their hydration from their food. A good example is a cactus; the interior of a cactus is quite juicy, which can provide enough hydration when consumed by animals.
yes there is, you can get the water from the cactus.
