  2. Introduction to Coral Reefs • The coral reef is the Oceans Rain Forest. Coral reefs normally live in tropical regions.  Some reefs live in places that are cool, but never cold areas. The coral reefs are found around the world in warm places (about 68-82 digress F). • The coral reefs are in waters about 150 feet deep because they require sunlight to survive. The reefs frequently develop in areas that have wave action because the waves transport in food, nutrients and oxygen. Reefs also need oxygen to grow. Which is more often found in shallow warm waters. • http://kids.nceas.ucsb.edu/biomes/coralreef.html#animals • http://library.thinkquest.org/04oct/00042/

  5. Brittle Star The brittle star (also called the serpent star) is a spiny, hard-skinned, long-armed animal that lives on the rocky sea floor, from shallow waters to great depths. • Brittle stars are NOT fish, but are related to sea stars. • The most common brittle star is the long-armed brittle star, a gray-blue, luminescent (glowing) species. • http://www.enchantedlearning.com/subjects/invertebrates/echinoderm/Brittlestar.shtml

  6. Sea Horse Seahorses are a type of small fish that have armored plates all over their body (they don't have scales). They live in seaweed beds and coral reefs in warm water and are very slow swimmers. Seahorses can change their color to camouflage (hide) themselves in order to hide from enemies. The female seahorse produces eggs, but they are held inside the male's body until they hatch; he is pregnant for about 40 to 50 days. The sea horse is the only animal in which the father is pregnant. http://www.shutterstock.com/pic-63414628/stock-photo-sea-horse.html http://www.enchantedlearning.com/subjects/ocean/Oceanlife.shtml

  7. Sea Grass Sea grass are flowering plants that live in the coastal waters of most of the worlds’ continents. Sea grass has adapted to living in habitats behind the coral reefs (back reefs) where they trap sediments from overloading coral reefs. Sea grass provides transferable food and oxygen to the coral reefs. • http://www.seagrasswatch.org/seagrass.html

  8. Human Activities

  9. Ocean Pollution • One of the leading threats to the coral reefs is pollution of ocean water. Every year gallons of oil and sewage pollute the ocean. All of this causes water pollution. • These impacts reduce the firmness of corals. Higher temperatures lead to heat stress, which causes the coral to banish the algae that live in their tissues in a protective, symbiotic relationship. • Algae is what they eat, and without it they don’t get enough food. This leads to the point where the polyps can’t grow or reproduce. • http://www.buzzle.com/articles/threats-to-coral-reefs.html • http://weheartworld.com/featured/coral-reefs-face-extinction/ • http://library.thinkquest.org/CR0215471/coral_reef.htm

  11. Over Fishing • Fishermen are the most humans that impact the coral reefs. • They use spear guns, commercial poisons, and sometimes dynamite for fishing. All of these materials damage the coral reef! • When the fisher men overfish in the coral reef area they cause damage to food chains around the reefs also. Specifically to the Great Barrier Reef, overfishing has caused a shift in the reef ecosystem. • http://library.thinkquest.org/CR0215471/coral_reef.htm • http://library.thinkquest.org/J0112412/coral_reefs.htm • http://sitemaker.umich.edu/gc2sec7labgroup3/over-fishing

  12. Over Fishing Impacting the Coral • official%26biw%3D1009%26bih%3D532%26tbs%3Disch:1&itbs=1&iact=hc&vpx=132&vpy=73&dur=1983&hovh=195&hovw=258&tx=129&ty=109&oei=FyBNTbPBLsS4rAfFz_XZBg&esq=1&page=1&ndsp=15&ved=1t:429,r:3,s:0

  13. Our Opinion

  14. Why do we humans Pollute the coral? Sometimes Humans pollute the coral because it is a way if getting rid of their wastes. • Also because of the high costs of safe disposal. • http://answers.yahoo.com/question/index?qid=20071201025843AAKWANV • http://www.google.com.qa/imgres?imgurl=http://www.underwatertimes.com/news2/brain_coral_pollution.

  15. Why is over fishing being done? • Even though there has been a drop of about 12 million tons in how many fish are caught, the fisher men are still catching fish even though they don't need the fish. • http://www.google.com.qa/imgres?imgurl=http://business-ethics.com/wp-content/uploads/2011/01/ • http://sitemaker.umich.edu/gc2sec7labgroup3/over-fishing

  16. Our Thinking • The threats toward the coral reefs are growing everyday. I believe that humans should not interfere with the coral reefs since humans have damaged the ocean seabed’s. Did you know that more than 1,500 species of animals depend on the coral reefs this means that human beings are damaging homes of more than 1,500 species of animals. • http://www.nationalgeographic.com/features/00/earthpulse/reef/reef1_flash.html • http://www.solcomhouse.com/coralreef.htm
