    Coral Reefs
    Coral reefs are among the most diverse and productive communities on Earth. They are found in the warm, clear, shallow waters of tropical oceans worldwide. Reefs have functions ranging from providing food and shelter to fish and invertebrates to protecting the shore from erosion. Through symbiosis with unicellular algae (zooxanthellae), reef-building corals are the source of primary production in reef communities. Because of the important ecological and economic roles coral reef communities fulfill, an understanding of the stresses and dangers to the reefs is necessary. Fortunately, many of the human induced hazards to coral reefs can be remedied.
    ==Sea Turtles== Sea Turtles
    Sea turtles, air-breathing reptiles with streamlined bodies and large flippers, are well adapted to life in the marine environment. They inhabit tropical and subtropical ocean waters throughout the world. Although sea turtles live most of their lives in the ocean, adult females must return to beaches on land to lay their eggs. They often migrate long distances between foraging grounds and nesting beaches. All 7 species of marine turtles are listed under the Endangered Species Act (ESA); 6 of those species fall under the jurisdiction of the NOAA Fisheries Office of Protected Resources.
    ==Whales:== Whales:
    Or Cetaceans , the group of mammals that includes the whales, dolphins, and porpoises. Cetaceans have very strong social ties.They travel, sometimes in groups (pods), from cold-water feeding grounds to warm-water breeding grounds.Whales are large, magnificent, intelligent, aquatic mammals. They breathe air through blowhole(s) into lungs (unlike fish who breathe using gills). Whales have sleek, streamlined bodies that move easily through the water. They are the only mammals, other than manatees (seacows), that live their entire lives in the water, and the only mammals that have adapted to life in the open oceans.

    Sharks:

    Sharks belong to the class of fish, Chondrichthyes. They live in waters all over the world, in every ocean, and even in some rivers and lakes.Some sharks live near the surface, some live deep in the water, and others live on or near the ocean floor.There are many different species of sharks that range in size from the size of a person's hand to bigger than a bus. There are about 368 different species of sharks, which are divided into 30 families. These different families of sharks are very different in the way they look, live, and eat. They have different shapes, sizes, color, fins, teeth, habitat, diet, personality, method of reproduction, and other attributes. Sharks vary greatly in their diets, but they are all carnivores.

    Midnight Zone
    The midnight zone is also called the Aphhotic Zone. Ninety percent of the ocean is the midnight zone. This zone happens to be the bottom zone, so it is completely dark. Very few creatures in the ocean live in the midnight zone because the water pressure is extreme and it is near freezing down that far. One problem caused by pollution that occurs in the midnight zone is called anoxic water. This means that there is no or hardily any dissolved oxygen in the water. When there is no dissolved oxygen, fish and other creatures can’t breathe, and they will quickly die from a lack of oxygen. Some of the creatures that live at this depth might die or migrate to other parts of the ocean. If they do migrate, there is a possibility that there could become a problem in the food chain.

    ...
    Deserts take up one-third of the Earth's land surface. The temperatures in deserts vary seasonally, with high daytime temperatures in the summer going as high as 113 degrees F or 45 degrees C, and also low nighttime temperatures in the winter going as low as 32 degrees F or 0 degrees C because of the humidity. One use of water in the deserts is to trap “infrared” radiation from both the sun and the ground, and dry desert air is incapable of blocking sunlight during the day or trapping heat during the night. Because of this, all of the sun's heat reaches the ground. As soon as the sun sets the desert cools quickly by radiating its heat into space. If you have noticed, deserts are usually always located near large mountain ranges because mountains can block the passage of moisture-filled clouds, which limits precipitation. If you visit a desert you may come across Sand dunes (ergs) and stony surfaces (Hamada surfaces). These make up a minority of desert surfaces. Minimal soil development and vegetation rarely occur because of the exposures of the rocky terrain.

    Goods/ Services/ Uses of a desert
    You may not realize it, but there are many valuables in the desert. These valuables including minerals such as gypsum, copper, gold, silver, chromite, uranium, lead-zinc, and much more. Deserts are not ideal places to live, but one good thing about them is that they are also ideal places for artifacts and fossils to be preserved.

    Coastal and Cold Desert
    Coastal deserts are found in areas that are fairly warm to cool, such as the Neotropic and Nearctic territory. The winters are usually cool and short, while the summers are long and warm. The soil is mostly sandy with a high alkaline content, its also very absorbent, so rain seeps rapidly into the ground. Most of the vegetation in the coastal desert features thick plant life, with good water preservation, and their roots are close to the surface of the ground to get as much water as they can before it drains into the soil.

    Animals
    The armadillo lizard is a type of lizard living in the desert. It has protection all over its body to protect its underbody. The Armadillo lizard can be found in the deserts of the southern tip of Africa.The body length is 15-17 inches, the tail is 14-16 inches long, and it weighs 8-17 lbs. The head, body, and club-like tail are all flattened, enabling it to wriggle easily into rock crevices for shelter. It may also adopt a curious defensive posture when threatened by rolling itself up like an Armadillo, with its tail tightly held in its jaws, presenting a spiny ring to the predator and protecting the softer, vulnerable belly area. That's why its called the Armadillo Lizard. The armored Armadillo Lizard has protection all around its body so that predators can't harm any of its under parts. Also squeeze into small places for escape. Another protection is their spiny scales that go all the way around its body. Their tails and spines also can be used to defend themselves as well. The Armadillo Lizard can be found in the deserts of the southern tip of Africa.

    The kangaroo rat lives in the desert scrub of the Mojave and Sonoran deserts of California and Arizona, and western through southern Nevada. These are the most arid desert regions in the United States.
    They live in large dens with wide openings which they dig themselves at the base of bushes. It spends most of its day underground sleeping, and comes out to feed at night when it is cooler.

    The kangaroo rat mostly eats seeds, leaves, stems and insects. It has adapted to desert life by getting its water from the food it eats. Another great adaptation the kangaroo rat has is a cheek pouch, which it can store food in for weeks while finding shelter. Another is its big, long, fluffy tail. It uses its tail for balance and steering its way.

    The Desert Tortoise can be found in the Mojave and Sonoran Deserts of southern California, two of North America's four deserts.
    Its front legs are muscular and flattened with long claws, and are very well adapted for digging deep burrows. Desert Tortoises can make hissing, popping, and poinking sounds, usually out of fear or distress. Its domed, brown shell can grow to be 9-15 inches in length, 4-6 inches high, and the tortoise can weigh from 8 to 15 lbs. They usually live to be about 80 years, but some have been known to be a 100 years old.

    The Thorny Devil is an endangered animal. People have been saving the Thorny Devil's nests and eggs by placing wire enclosures around the nests. By doing this they are keeping predators out and hold the babies in after hatching. This technique seems to be working.

    Vegetation
    Shrubs are dominant in the deserts and are either evergreen or deciduous. They usually have small leaves, and often have thorns or spines, even possibly aromatic oils. They have shallow roots because there is little precipitation each year.
    ...
    {http://www.cactuslimon.com/images/Lithops_Karasmontana_H1.JPG} LithopsMost of the vegetation in the desert space out from each other to prevent competition for water. In fact there are some plants that have special chemicals and poisons in their roots to stop things from growing near by.
    Some plants have roots that both reach down deep and are rather shallow. Yet others slow down their growth rate for the drier part of the year and some direct the shiny side of their leaves toward the sun to help reflect its rays away.

    Current/Major Stresses-Human Impacts on Desert
    The desert is unfriendly to human life. Because of this it has been preserved from being overrun by things that could destroy it.

    Soil Stability and Water Retention
    Biotic desert crusts are important in the stability of deserts because they are more resistant to wind erosion than sand. Lichen is an important component of soil crusts because it has a high water holding capacity. Photosynthesis of lichen is improved due to the high water holding capacity because it is water dependent. Wind erodibility of the soil is increased by the disturbance of soil crusts. Soils that had undisturbed crustal development are the only soils that are able to withstand high wind speed in the desert.
