The desert is full of beautiful plants and animal life but it hides the fact that some of them are hostile
Like what for example?
The amount of biodiversity is amazing and a good example would be the flowering cactus,  which may look nice but will protects itself with its thorns  
I really like cacti plants.
They are amazing and there are about 1750 known species of them.
Do they all flower?
drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water. Almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help
good growing conditions can grow all year round, whereas other plants in suboptimal conditions will not be able to do this. This fact is one example of the versatility of the herb, which is able to easily adapt to its environment. This versatility is also demonstrated in the flowering period of "S. hispidulus" which is estimated to be from October to April, but is differently assessed by New Zealand Plant Conservation Network to last from August to May which is a very large time period for flowering to occur. But it is
