Transcript of Great White Shark

Carcharodon Carcharias Population Biotic and Abiotic Factors Sharks are on top of the foot chain so they don't have many predators besides humans. Abiotic: Rocks, Sand, Sun, Water, Salt, Temperature. The male shark first bites the female shark in order to keep her in place while insemination. The female shark then grows an egg and her gestation period last for about 12 to 18 months. Only one baby is born at a time. Competition to Survive Great White Shark I chose to research the Great White Shark because I love marine biology and swam with the sharks this past year. They are extremely important to the food chain of the ocean and to our environment so losing them to distinction would be devastating. Some estimate that there is as few as 800 Great Whites left in the world and some estimate that there is up to 2600 Great Whites. There is no definite answer, but we do know that their numbers are decreasing dramatically across the globe. Biotic Factors: Fish, Turtles, Seaweed, Krill. What do Sharks eat? Great White's are carnivores, meat eaters. They eat animals with high fat contents. They eat fish, tuna, stingrays, smaller sharks, porpoises, dolphins, whales, seals, etc. Reproduction Habitat Destruction Pollution in the ocean is the main destruction of habitat for sharks. Adaptation Fins and streamlined bodies. Countershading colors. Tough skin. Mans Impact and Interdependence They are at the top of the food chain so they are independent. Humans are developing an appetite for shark and kill man a year.
