The Desert

World Map of Desert Location

This is a picture of a Camel. Camels have many adaptations that help them survive in the desert. First off, Camels have two rows of long eyelashes. This helps protect against blowing sand and the sun. Second, all of a Camels fat is stored in the humps on their back. This helps the Camel to survive long periods without food and water. Next, Camels have thick leathery patches on their knees. This helps protect the Camel from getting burnt when it kneels on the hot desert sand. Also, Camels have broad, flat, leathery pads at the bottom of their hooves. With this, the pads spread out when the Camel places its feet on the ground thus creating a "snowshoe effect" and preventing the camel from sinking into the sand. And lastly, Camels have long strong legs.This keeps its body further away from the hot sand.

This is a picture of a Meercat. Meerkats have many adaptations that help them survive in the desert. First off, they have ears that stick out of the sides of their head. With this, they can catch sound better of what's in front of them and to watch out for predators. Another thing is that Meercats have eyes that sit on the front of their head. With this, they have binocular vision, a wide range, and depth perception. Meercats have developed long, curved claws to dig in order to burrow underground and eat bugs. Meerkats have silvery-brown fur to camouflage them to their dry, desert surroundings.To scan the area,they use their stocky hind legs to stand on and watch for predators. And lastly,Meerkats are immune to poison in order to withstand venomous bites and strikes from snakes and other animals.

Desert areas receive an average of less than 25 cm of rainfall each year. The average temperature of a desert area varies by desert, but is mainly 68-77 degrees Fahenheit.

In order to survive, desert animals have developed a number of ways of adapting to their habitat. The most common adaptation in behaviour is staying in the shade of plants or rocks or by burrowing underground in the heat of the day. Many desert animals are nocturnal: they stay inactive in shelter during the day and hunt at night when it is cool. Some animals get all the moisture they need from the insects, plants and seeds they eat, and do not need to drink water. Fat increases body heat, so some desert animals have concentrated the body's fat in one place, such as a hump or tail, rather than having it all through the body.

To the left, this is a picture of a Creosote Bush. The Creosote Bush has a few physical adaptations that help it survive in the Desert. First, The Creosote Bush has a water-proof covering to help prevent it from losing water. This coating is made of a special kind of wax. The Creosote Bush drops its leaves to conserve water when its too hot in the Desert. Even when other plants stop growing because there is no water, The Creosote Bush still produces sugar. The Creosote Bush also has a special wax on its leaves so it won’t die as quickly as other bushes in the hot sun. After a rainfall, The Creosote Bush puts out new leaves and flowers right away. When it does this, it helps bees pollinate and survive. Many other animlas depend on this bush as well.

To the right, this is a picture of a Barrel Cactus. In order to survive in the desert, the barrel cactus has many physical adaptations. It has spine needles to protect the flesh from being eaten by animals. It also has ribs to hold it tall. Another thing is it has shallow roots to collect the rain water. It has blossoms to attract bees to pollinate it. And lastly it has fruit for seeds to reproduce.

The plants of the Desert habitat area have adapted to its dry, hot extremes by using their own sort of adaptations. Some desert plants, usually have special ways of storing and conserving water. They often have few or no leaves, which reduces water loss. Other plants have adapted to living in the desert by growing very long roots, allowing them to get their moisture deep within the earth, at or near the water table. Also, another type of plant in the desert survives by remaining dormant during the dry periods and come to life when water is available. After heavy rain they complete their reproductive cycle quickly. They bloom for a few weeks in spring. Their seeds remain dormant in the soil until the next year’s rain.
