Evolution Of The Carcharodon Carcharias ( Great White Shark )

The Great White, up to 21 feet long with razor teeth may seem like a monster but there is much that society does not know. Sharks need to be protected because of the benefits they give humans. Also by tracking sharks is one way researchers can find a way to understand sharaks more.

Every Jaws fan knows the shark gets it in the end. What they do not know is that too many sharks have gotten it; and that has caused a rapid decline in the shark population over the past thirty years. Since the 1970's, sharks of the Atlantic and Gulf of Mexico shores have declined eighty-five percent. Sharks are vital animal to our world's ecosystem, and if the decline is not controlled; we could be facing devastating problems in years to come. Information has been obtained from two books: The Shark Almanac by Thomas B. Allen and Sharks, An Introduction for the Amateur Naturalist by Sanford A. Moss. Sources also include a number of online references, among them BBC News, ENS News, The New York Times, and two online scientific

Sharks have been in existence for more than 300 million years. Their evolution occurred over 150 million years earlier than that of the dinosaurs. Most of the existing fossil data of early sharks was collected from fossilized teeth together with several skin impressions. primitive sharks (Cladodonts) , had teeth which were double-pointed, up to 2metres in length, ate fish as well as crustaceans, and existed approximately 360 million years ago.

For 350 million years, sharks have swum the earth and sought out their prey. Before the dinosaurs every set foot on earthen shores, sharks lurked in the murky depths of the ocean. On the North Shore Shark Adventures tour, you will be introduced to the Sandbar and Galapagos sharks. If you are really lucky, a Tiger shark may make an appearance.

The scientific community views sharks as important top predators in the oceanic food chain and as misunderstood creatures of the

Thanks to the movie Jaws, many people are scared of sharks. Seeing a fin in the water terrifies all but the most experienced of beach goers. Sadly, this perception means that most do not really care if the sharks are hunted to extinction or not. However, society’s opinion on sharks needs to change if we want any hope of saving the world’s oceans. Sharks, as an apex predator, are an important part of the ocean’s food chain.

Sharks, have been on earth for 400 million years, making them older than dinosaurs, and they have lived on earth massively longer than humans. Shark culling has been witnessed since the late 1960’s by Australian’s because of a fatal shark attack on two males at that time.

According to McComb, Tricas, & Kajiura (2009), there are several features of the hammerhead shark that have changed over time. Most notable, though, is that the shape of the head has continually expanded over time, emerging the the unique shape for which this species has been understandably named. Along with the lateral movement of the head, the sharks also had to compensate for the changes through adapting a new eye shape and process for pupil dilation as the placement of the eyes had also moved. Scientists believe that this adaptation helped the sharks by providing the ability to adjust their vision to changing light intensities when transitioning from deep to shallow waters for hunting. Additionally, the newer eye location provided hammerhead sharks with a greater overlap in their binocular fields as compared to their shark relatives, limiting the amount of space affected by blind spots within visual field (McComb et al., 2009). Ultimately, these structural adaptations enhanced the shark’s ability to hunt and survive in various parts of the

Most people are terrified of sharks and want nothing to do with them others love them I’m one of the ones that love them I think they are just misunderstood intelligent creatures and this will help you realize that too. Sharks have been on earth for at least 420 million years ago that’s 200 million years before the first dinosaur! Sharks outlive humans they have been on earth longer and have longer life spans the oldest living shark is 500 years old while the average human can live as long as 70 years in perfect health. Sharks like people come in all shapes and sizes and swim everywhere from the arctic circle to the Caribbean. Some sharks are big some little some long and thin some wide and short they come in every size imaginable and in the weirdest conditions like seas and oceans with other animals ready to eat any injured sharks to lakes hunting fish they live almost everywhere.

The theory is that rouge sharks are sharks that have chosen to prey and attack humans, and some believe they have developed a ‘taste for human flesh’. Great White Sharks are highly efficient predators and are known as apex predators, they top the marine food chain and are extremely dominant specie of sharks. This essay discuss the question, should rouge sharks be killed or conserved? The Great White Sharks population was threatened in the 1970’s and 80’s from overfishing, this caused a global concern which led to Great White Sharks are protected under the Federal Environment Protection and Biodiversity Conservation Act since 1999.

Great White Sharks have known to be a great source of fear throughout the numerous ages of sea exploration. With an average size of fifteen feet in length, it’s not hard to imagine why. They are the stuff of many nightmares, but they are largely misunderstood. There isn’t a lot of information on Great White behavior because many believe them to be an endangered species, due to dwindling food sources and overfishing. However, with conservation efforts, their numbers should rise and more studies can be done. The latest major discovery was just in 2014, which shows that with time, we can learn even more about them. In this paper I will study the sharks’ basic facts, their various behaviors, and the effect humans have on them.

Did you know that only four out of the 400 species of sharks attack humans? Sharks benefit both humans and other aquatic creatures. This is why sharks need to be protected and tracked. Sharks aren't really the demonized creatures we all think they are. To begin with, there are only 400 species of sharks, only four attack and the blue sharks are not one of them.

For millions of years, sharks have thrived, with nothing to fear. But in recent years that has changed. Over the past 10 years, an average of 100 million sharks have been killed every year. That’s right, 100 million sharks Every year. In some parts of the world, sharks have completely vanished. It does not have fanged teeth or strangling tentacles. It doesn’t even live in the sea. The creature killing the sharks is the human being. The disappearance of sharks had an effect on the ecosystem. Because of overfishing off the east coast of the U.S bull sharks have had

Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man. Sharks are classified in the order

Before a shark can hunt, he needs to locate his prey. Sharks' highly developed senses allow them to detect even the most minuscule hints that prey might be near. A shark's sense of smell is so acute that he can detect a single drop of blood in an Olympic-size swimming pool. He can tell which nostril picks up the odor first, allowing him to turn in the direction of his potential prey. "Lateral lines" that run down each side of the shark's body allow him to detect vibrations or pulses in the water, and small pores in the shark's snout, called ampullae of Lorenzini, let him detect electrical impulses emitted by other
