Introduction Hammerhead sharks are an endangered species of animals. Here are some facts about about the marvelous hammerhead shark. Hammerhead sharks are sharks that have big hammer-like head sculptures. That’s why they are called hammerhead sharks. They are part of the fish family. The hammerhead sharks hammer like head helps it hunt for food, such as stingrays, its favorite prey. The hammerhead shark can pin the stingray to the ocean floor with his hammer-head. Another part of it’s body that can help it hunt for it’s prey is the hammerhead’s wide eyes. Having these large eyes helps it by allowing it to see it’s prey from far away before it’s prey can see them. This gives them a great advantage. Hammerheads also have an organ called ampullae of Lorenzini. These organs help it sense if its prey, like stingrays, are hiding under the sand. This way it could catch the stingray without the stingray knowing that it’s there. As you can see, hammerheads are very carnivorous. The average lifespan of a hammerhead shark is 20 to 30 years in the wild. They are usually 13 to 20 feet long. They are most of the time 500 to 1,000 pounds. When they are in a group, they aren’t called a group or gang; they are called a school or shoal. They are found in tropical and temperate waters. They migrate from very hot waters and they try to find cooler places. They have gray brown to olive green on the top of their bodies. Just like most other sharks they have white undersides. Their top colors help them hunt and hide. From above they blend in with the ocean’s color. Their teeth are triangular and saw like. Hammerhead sharks have tall and sharp dorsal fins. Lastly, Hammerhead sharks are usually not harmful. Most are small, so just leave them alone. What would happen if this animal was extinct? If this animal were extinct, a whole ecosystem may be wiped out. This doesn’t sound so like it would really happen, but it will. In a food chain, the hammerhead shark is at the top of the chain, so if they die
out, there could be these effects: 1) Overpopulation of it’s prey. 2) If the hammerhead shark dies out, the prey would be overpopulated, which would eventually lead towards a lack of food for those fishes. 3) The same overpopulation would happen to the the smaller fishes in the food chain, on, and on, and on until the whole ecosystem is gone. Habitat Description The hammerhead shark’s habitats are the tropical waters of the world. They live in places with more coral, just like other sharks. If you go snorkeling in a tropical place with lots of coral, for example the Caribbean, you shouldn’t be surprised to find lots of sharks. In fact, hammerhead sharks are found in Hawai’i. You probably wouldn’t see a big hammerhead shark. Normally they are small. Why are hammerhead sharks considered endangered? Hammerhead sharks are considered endangered because of these reasons. First, hammerhead sharks are endangered because lots of people love “shark-fin soup” and obviously you need a shark fin to make shark-fin soup. Also, people love to overhunt hammerhead sharks for the joy of it. Humans are also polluting the oceans. Run-off of pollutants from the land into the oceans contains pesticides, sewage, etc. What can we do to save hammerhead sharks In order to save hammerhead sharks we can stop hunting them for fun. We could also stop polluting their homes. So please help save the hammerhead shark. They are endangered and need help. Spread the word tell others to help. Bibliography "Hammerhead Shark."
