Shark! For many, their size, power, and great, mouthwatering jaws fill us with fear and fascination. Not for me, I’m bewitched by them. Sharks kill only a few people each year, but media coverage and movie representation of attacks have marked sharks as voracious killing machines. Our fears—and appetites—fuel an industry that hunts more than 100 million sharks each year and threatens to purge these vital predators from the oceans.
The shark is an enchanting creature, over 400 different swim in the ocean today. Too many, sharks symbolize the terrible essence of ruthlessness, representing the ultimate savages of the seas. Although many folks would rather not deliberately socialize with these fearsome predators of the depths, I appreciate swimming among sharks. Sharks in addition to their direct predecessors are swimming within the world's oceans for well over three hundred million years, and were going about their business long before dinosaurs walked the world. The fact that sharks have survived thus far without changing very much is a long real tribute to the effectiveness of their anatomy.
Sharks are fishes, confined within the taxonomic class called Chondrichthyes (meaning "cartilage-fish"). Sharks besides other cartilaginous fishes (rays, skates, and rat fishes) differ from the skeletal fishes because sharks have a cartilaginous skeleton, and lack a swim bladder. Worldwide there are over six hundred different types of fish, not to mention three hundred species of sharks.
From time to time sharks are referred to as primitive creatures. They are a prehistoric group of animals, so assuming sharks are primitive is correct. Unfortunately, this assumption is wrong. Recent offshore studies have shown that sharks are, in fact, extrem...

...ba diving, I read countless articles about sharks, monitor shark tracking’s and even watch shark films.
Everyone is entitled to their own opinion about sharks; some people have been mistaken as a source of food while others simply don’t like sharks. For the sharks sense of not knowing these marvelous creatures have been and continue to be brutally punished for trying to live. Sharks have been on this earth longer than any human has and still to this day they remain helpful in cleaning up our ecosystem.
I hope that the information contained in this essay inspires curiosity about sharks and awakens respect and care for one of the magnificent, most ancient creatures of an ever-evolving sea.

Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.
The bull shark may be responsible for many shark attacks in the world but I believe that we have no right to kill them. Sharks are very important to animals food cycles and if the food cycles get messed up it can greatly effect the world. In fact, the bull shark is more vulnerable to human impact due to their ability to live in fresh and salt water but many sharks that are killed are for either shark fin soup or their liver oil. The sharks liver oil has many uses now but it started as a machine lubricant. Another way that sharks die is by recreational fishing. The sharks can get caught up in the fishermen's nets and eventually suffocate and die. As an environmental community, I feel like we need to inform people about shark habits and how to keep sharks safe. The water is their home and we are
This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because they mistake surfers for seals. In earlier times, the ocean was a source of mystery and adventur...
Everyone knows the famous opening tune to the famous 1975 Spielberg movie Jaws, which portrays the chaos that sharks can cause. From then until now, movies that showcase the ever-violent personalities of sharks have been popular in the media. They are seen as the face of oceanic brutality, whether they bite off people’s arms or cause turbulence in beach parties. Little does the world know about the dangers that we, humans, do to these natural predators of the oceans.
Great white sharks are the main predators in the ocean. The only things that are responsible for the deaths of sharks are Age, Health, Humans and other sharks. Humans are responsible for 70% of deaths for great white sharks. Today there are more than 440 known species of sharks. Great whites only have 2-12 babies at one time unlike others who have hundreds. Great whites can live up to 60 years old! Great white sharks are phenomenal animals and but still are vulnerable to extinction. Do your part to kill of the rest of them before they kill you!
Mojetta wrote about prehistoric sharks, and the history of these creatures. According to Angelo Mojetta, author of Sharks, Cladoselache genus, one of the first prehistoric sharks, was buried in sediment that kept it preserved. Unlike other sharks, Cladoselache genus had a circle of tiny plates around it’s eyes for protection against it’s victim’s attempts to fight back. These sharks lived over 400 million years ago. Sharks of the past could mostly be identified by their teeth, because shark’s bodies are made of cartilage. Another shark that was focused on was called, Stethacanthus. This shark had a very unique look. Stethacanthus had a brush like decoration on the top of it’s head, and an extra fin like part that had the same bristle like decorations on it. These characteristics were thought to be used as suction cups, to hitch rides from larger fish. One of the most famous sharks that looks like an over...
When most people think about sharks, they probably picture something like this. A big, horrifying shark, with many sharp teeth longing for the human flesh. They are scary, dangerous and killing machines. But it isn’t the truth. In fact, this is a fake.
Sharks appear to be very vicious creatures that will eat or kill anything in its path. People think that all sharks are harmful and deadly to humans. However, research shows that this statement is not true. Sharks can be trained and tamed. They are just like big, aquatic dogs. Only about 2 dozen types of sharks are potentially harmful to humans. Shark attacks are also much more uncommon than one may think. Despite their fearsome appearances, sharks are not as vicious as they look.
Shark slaughter is a cruel and violent act, to say the least. Granted that there is economical profit to be had from shark finning, the massive loss incomparably outweighs the profit. Most, if not, all humans would not enjoy having their limbs cut off and being left to die. It is simply inhumane and brutal. However sharks are experiencing this very thing, and the fact that they cannot express or protect themselves, is leading to the death of hundreds of millions of innocent sharks annually. Odds are that as you are reading this, a shark was killed. While sharks may not be the most adorable animals on the planet, they certainly are living creatures, and they feel pain just like us.
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
When most people hear the word "shark", the image of a vicious killing machine pops into their head. They picture something out of the movie Jaws, where a massive Great White shark terrorizes an entire beach and eats dozens of people. However, this fictional story is nothing more than Hollywood entertainment. In the real world, the tables are turned. Humans are the ones who kill sharks, and not just by the dozens. It has been estimated that over 100 million sharks are killed every year by humans (http://www.iflscience.com). Some estimates claim that the actual number of sharks killed every year could be as high as 273 million (http://www.iflscience.com). In this research paper, I will inform you of the many ways that sharks are being killed,
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the

One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in any warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans. The whale shark is a species with a fascinating ecology, life history, behavior, anatomy
