A head that looks like a hammer, one eye and nostril are located on each side of the head, extra-tall dorsal fins. They grow to about 3 feet (0.9 meters) to 20 feet (6.1 meters). They weigh to about 230-450 kg (500-1000 lbs). They are usually grey, brown, or white. They have smooth skin.…

I’m researching the Hammerhead shark it has many unique features . It has a oddly shaped head used for hunting . They live near the equator or in tropical waters . They are carnivores and eat about anything and their favorite food is the sting ray . The hammerhead shark is very unique .…
Although evidence has shown that there is a recent change in the increase of the cownose ray that has caused a large boom, it's Well known that the cownose ray is a predator of shellfish when the water becomes warm. The marine systems caused by the removal of sharks remain misleading, due to the significant declines in large coastal sharks in the northwest Atlantic Ocean, which caused dramatic increases in abundances of smaller elasmobranchs (referred to as “Macropredators”) over the predation release. The large coastal sharks decline allegedly led to an order of large scale increase in the population of Cownose rays. Thereby the ever-increasing feeding of the cownose ray has led to the concerns for the shellfish populations along the U.S.…
There is a vast amount of insects that roam this planet and many insectivores are needed to help keep their populations in check. Many have adapted to support a sustainable food source and survive on a diet solely of insects. One in such would be that of the Pangolin from that of many parts of Africa and Asia. Interestingly enough, this scaly mammal for its size, has the largest tongue of any mammal and as well the stickiest saliva. These adaptations give the Pangolin a better opportunity to catch prey such as ants and termites. They in turn walk on their hind legs and use their front claws for digging and the smashing of prey. Although sad, this little mammal has been sought after by many human poachers greatly affecting their population and sustainability in the wild. They…
Did you know that the venom of a Black Banded Sea Krait is ten times more toxic than that of a rattlesnake? Maybe this is why people are scared of snakes. Though their venom is very toxic, humans rarely get bitten. Unfortunately, the population is being threatened by habitat destruction. The Black Banded Sea Krait has its own ways of adapting to marine life, where it lives, and how they produce more of their species.…

The shark is known to be a terror of the ocean that does nothing more than kill human’s, at least this is what was think of these creatures until more research was discovered. The truth is that the shark is a beautiful creature that has more than 440 species that is being hunted to extinction. Not many people are killed by sharks, as it is more common to be killed by a vending machine, than a shark. These creatures do not need to be hunted, as they are already on the verge of extinction.…

Carcharhinus Leucas or bull sharks are the only species of sharks that are able to travel long distances and spend extended periods of time in freshwater environments. Although many people disagree, I believe that one of the bull sharks’ main reason for entering freshwater is to find breeding grounds. There is evidence that supports this theory, and it seems to me a very logical explanation, however it is a controversial concept. In this paper, I will discuss what physical characteristics allow bull sharks to survive in both marine and fresh waters, and attempt to understand whether they do this…
Did you know that almost eighty percent of the fish living on a reef could be killed by a single fish that is only about the size of a human hand? This fish happens to be called the lionfish and is mostly known for its beautiful features and deadly poison. Lionfish are indigenous to the Pacific Ocean; however, they have recently invaded the Atlantic Ocean and are growing in population at an uncontrollable rate. Marine biologists and even everyday snorkelers fear the dangers of these fish and have even started taking the matters of getting rid of them into their own hands. On the other hand doctors, chefs, and even snorkelers consider lionfish to be very useful and entertaining. According to marine biologists, the…
Growing up, everyone wants to be in the pros, or an actor. No one wants to be around slimy and stinky fish until retirement age. But one person did. That person is Eugenie Clark. Eugenie did not call it quits at retirement age however. In fact, Eugenie would continue to dive and study sharks at the age of ninety-two (MOTE). In this paper, you will learn about Eugenie Clark’s life, her contributions to the scientific community, her educational background, the passion for which she did her job, scientists that worked with her to reach a common goal, awards that Eugenie has won, and the knowledge on sharks from before Eugenie’s time, during her time, and now sadly, after her time.…
Great white sharks are known as the most dangerous of the shark species because of their sheer size and their quick mind that make them the ultimate predator. A comparison can be seen in Figure 1, where the great white shark is seen next to a human, this image is showing the sizing difference between the two species. The shark is so captivating that there is an entire week each year dedicated to these creatures to learn more about them and the world they live, in an area that is vastly undiscovered. There is enough evidence through fossils that can date the shark back four-hundred million years ago, which was a time before dinosaurs were roaming the Earth (“Shark Basics”).…
Barracudas may be apex predators within coral reefs, but humans will always beat that. Southeast Asia is a main place where coral reef fishes are eaten, including barracudas. The barracuda prevents overpopulation of organisms by consuming them. The barracuda’s main competition is sharks.…
