Transcript of "Shark Species In Coral Reefs Brandon Roy"

  1. 1. Shark Species in Coral Reefs By: Brandon Roy
  2. 2. Reef sharks (identification and classification ) <ul><li>Phylum: Chordata </li></ul><ul><li>Class: Chrondrichthyes </li></ul><ul><li>Diet : reef fish, lobster, cuttlefish, crabs, </li></ul><ul><li>Common sharks found in reefs </li></ul><ul><ul><li>Black-tip reef shark </li></ul></ul><ul><ul><li>White-tip reef shark </li></ul></ul><ul><ul><li>Caribbean reef shark </li></ul></ul><ul><ul><li>Grey nurse shark </li></ul></ul><ul><ul><li>Whale shark </li></ul></ul>
  3. 3. Reef sharks cont. <ul><li>Black-tip reef sharks have been found off the coast of Key West. </li></ul><ul><li>Tip of their dorsal fin is black, they have a brown body and can be up to 6 feet long. </li></ul><ul><li>They are one of the few sharks species who can jump completely out of the water. </li></ul><ul><li>White-tip reef shark have a white spot on the top of their dorsal fin with a grayish brown body(140-160 inches). </li></ul><ul><li>This species of shark is nocturnal and hunt in packs </li></ul>
  4. 4. Unique characteristics of sharks <ul><li>A tiger shark( grey nurse shark) can smell 1 drop of blood in an Olympic sized swimming pool </li></ul><ul><li>Whale shark is the largest fish in the world and can grow more than 15 ft long and live in coral reefs </li></ul><ul><li>All sharks have lateral lines down their body and face along with 2 spiracles behind their eyes that act as ears and detect vibrations in the water. </li></ul><ul><li>A sharks body is mostly composed of cartilage. </li></ul><ul><li>Most sharks eat 1-10% of their own body weight weekly. </li></ul>
  5. 5. Why are reefs good homes for sharks? <ul><li>The temperature rarely drops below 70 ° Fahrenheit, this temp is perfect for the cold blooded sharks. </li></ul><ul><li>Coral reefs are also home to over 500 species of fish that these sharks prey on. </li></ul><ul><li>The coral also provides shelter and protection from other sharks and fishing tourist. </li></ul><ul><li>The reefs also have very low levels of toxins in the water which is good for the reef sharks. </li></ul><ul><li>The constant changes in tide provide a very rich marine environment for the sharks </li></ul><ul><li>Estimates say that coral reefs contain up to 1/3 of the world’s population of fish. </li></ul>
  6. 6. Threats to sharks in reefs <ul><li>Over fishing – tourism and commercial fishing of sharks </li></ul><ul><ul><li>Fins (shark fin soup) </li></ul></ul><ul><ul><li>Oils (Shark liver oil) </li></ul></ul><ul><li>Sharks have slow reproduction so over fishing is hazardous </li></ul><ul><li>Oils from the liver are used for medical remedies (pains, sores, irritations) </li></ul><ul><li>The deterioration of coral reefs along with coral bleaching kills fish that sharks prey on </li></ul><ul><li>The fish trade is killing sharks to supply the demands of Chinese food industries </li></ul>
  7. 7. Conservation of Reef Sharks <ul><li>As mentioned in the previous slide, sharks are subject to over fishing. The IUCN, at one point, was responsible for banning all shark fishing in Australia. </li></ul><ul><ul><li>After noticing that the number of sharks increased dramatically, the bans where lifted </li></ul></ul><ul><li>Scientist are trying to come up with a way to improve the rate at which sharks reproduce. </li></ul><ul><li>Now the CITES are trying to ban fishing of tropical marine animals, in hopes of keeping some shark species from becoming endangered. </li></ul><ul><li>The CITES are also pushing to restrict the tourist fishing of certain shark species. </li></ul>
