They will be found in areas that are 0 to 2,500 meters above sea level. They like to make their home in open areas and in dense woodlands. They do not like lowland forests, desert and areas without trees. During the rainy season, they will go north and during the dry season they will go south.…

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”).…
First, the whale shark only has foot long babies. Then, there is the megamouth shark; the megamouth shark has a big mouth. Now, we have the frilled shark that, in my opinion, is the ugliest shark. The frilled shark looks ugly because of the scar looking things on it, and the weird looking gills. The frilled shark has lots of teeth that are razor…

Most sharks live in saltwater.1% of sharks live in freshwater. 1 kind of shark lives in the arctic oceans it is called the Greenland shark. The Greenland Shark hunts by it’s sense of smell only. Sharks are in every ocean in the world. Pelagic sharks, whale shark, the basking shark, and the megamouth shark all prefer the open ocean. They travel thousands of miles a day, and never stay in the same part. Some sharks stay in the ocean bottom. Those sharks are smaller sharks and they lie at the bottom just waiting for their prey.…
In the article I read, the focal organism is the reef shark and the food web consists of the algae (from coral), then the parrotfish and then the reef shark, or you have the algae (from coral), then the wrasse and then the reef shark. In this food web, the reef shark is known as the top predator and its trophic level is the quaternary consumer. “Sharks are important members of ocean food chains and removing them can have unintended consequences” (Meekan, 2013). When the reef sharks are removed from the ocean, the numbers of smaller predators increases but because there are more fishes such as snappers, this causes there to be less algae eating fish, for example, parrotfish. As there are less algae eating fish, the young coral in the ocean become…
Shark exploitation is any action of catching sharks from the sea and using their body parts for human use. Shark finning is removing the fins of sharks and either throwing them back into the ocean to bleed to death or kept for other human uses. The shark fins are used as food to make an Asian soup called shark fin soup. Shark finning only uses about one to five percent of the entire shark’s body. The rest of the shark’s body could be used as food for other communities in the ocean but is wasted.…
Contrary to popular belief, sharks do not commonly attack humans, but humans commonly attack sharks. People all around the world remove shark fins and leave the shark to die. This not only damages shark populations, but it also damages the economy and deprives many of much needed food. There are laws in place to regulate shark finning, but unfortunately, not everyone abides by the law. Some may argue that killing “vicious” animals is not something to be thought about twice, but shark finning is an inhumane and extremely wasteful practice that must end.…
For over 400million years sharks have been adapting themselves perfectly for life in the ocean. Their varied habitats, diets and physiology has meant that for many of them, these adaptions have been slightly different.…
