When people swim in the ocean, whether diving, snorkeling, surfing, or just playing on the beach, the thought of a shark attack is always looming on their minds. The fearful part is that sharks are unseen when approaching its victim. In fact, only about nineteen percent of shark attacks are fatal worldwide. About half of all victims are surfers, and they usually occur within 100 feet of the shoreline.1 The four most common sharks involved with attacks are the great white, tiger, whitetip, and bull. However, unknown to most except deep sea divers, is the presence of the goblin shark.
The goblin shark is found in every major ocean, but only at deep depths. Therefore, it constantly lives in darkness at high pressures. The goblin shark is usually

Since the goblin shark has weak muscles, its speed is not fast. This movement constrainment can affect how a goblin shark hunts. It is believed goblin sharks must sneak up on its prey from behind because its prey will most likely outrun the goblin shark if chased.3 However, if the goblin sharks hunt in groups, there would be a higher chance of capturing its prey. Many types of whales hunt in pods, they circle their prey until closing in. This would be an effective method for the goblin shark. Also, if the goblin shark were threatened by a predator, there is more power in number for defence and safety.
Another restraint the goblin shark has is its poor eyesight.3 They have small black eyes which do little to help it be aware of its surroundings. Alone they would struggle to survive against an advancing predator or obstacle, but in a group there is less room for error when multiple sharks are able to watch out for oncoming hazards.
It is every animal’s instinct to do whatever it takes to survive, and if, for the goblin shark, that involves staying in a group, they will. Alone the goblin shark would have struggles in survival due to its eyesight and muscle strength, so the best option for the goblin shark is to bond together to hunt and swim. Most fish swim in schools, so why not the goblin
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 known to thrive in the Mississippi River and around Nicaragua but are wide spread throughout the world. The bull sharks have an ability to penetrate far up bays and rivers. Some bull sharks have even been found as far as a couple hundred kilometers from the sea. Bull sharks have also been found in Potomac river. Potomac river is located in southern Maryland and is about 405 miles away from the ocean. There has never been a reported shark attack in Maryland which seems crazy now knowing that bull sharks have been found only 200 yards away from the point lookout state park in Maryland. What is crazy is that bull sharks have the abilities to travel in many different environments and depths but tends to stay in shallow waters between 3-30 meters of water.
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...
Don is a blue shark that Ocearch tagged. Don lives in an aquatic ecosystem in the North Atlantic Ocean. Don was tagged on August 27,2016 in Cape Cod. The most recent he pinged was November 29, 2016 @ 1:47 p.m. He weighs 311
Finally, goblin sharks. Goblin sharks got their name from a japan word tengu-zene. Goblin sharks use their teeth to trap their prey inside their mouth. Goblin sharks have teeth in their body that chew their prey. According to the text a man caught the
While, these horrific fish are bloodcurdling there is ways to keep them away, such as a magnet. “Magnets made from iron, boron, and neodymium is a promising repellent being developed by SharkDefence” stated in Stopping Sharks by Blasting Their Senses. Magnets effect the shark’s Ampullae of Lorenzini. Another way, is specified
Many believe that sharks are very dangerous animals,but they’re very delicate. So many sharks have been mistaken for other accidents like oil plant explosions,deaths which is kinda true,but my point is they are just like us. They’re very elegant creatures in a way that is both aggressive and agile. Ever wonder what the fastest sharks is? The Mako shark can get up to 60 which is fast in shark speed.
What do sharks use to find prey? It is their very strong sensitive nose that can detect a drop of blood from miles away! Where are sharks commonly found? Sharks are found at coastlines like Bull sharks and near the equator.
’’They are gray-brown to olive-green on top with off-white undersides,and they have heavily serrated,triangular teeth’’(National Geographic ‘’Hammerhead Sharks’’ 1).These are the usual colors of sharks. When you visualize a shark,the shark you would see would most likely resemble a bull shark. ’’They they almost resemble tiger sharks,and the problem is that tiger sharks are even more dangerous than bull sharks. To be honest,if you have to be extremely afraid of one species of shark,then it would probably be the bull shark. ’’Among the most likely sharks to attack humans,bull sharks favor shallow coastal waters-the same places humans prefer to swim’’(National Geographic ‘’Bull Shark’’ 1).This means that the bull shark would be the most feared by humans because they swim in the same places that humans swim.
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.
For centuries, humans have been hunting sharks for sport, food, medicine and leather with little regards for the health of the shark population (Allen, 1999). Sharks are considered one of the most challenging fish to catch, and their ...
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
This occurred through increasing kidney strength in order to release water by urinating often when in fresh water, (Fresh Water Sharks, 2013). Another way sharks are able to distribute it by living in different depths of water. Over years some sharks have adapted to living in the bottom of the see where it is cold and dark in order to not be preyed on. Furthermore, some have the ability to camouflage into the sea bed to protect themselves, and to be able to hunt. While other sharks can swim fast and are bigger in order to compete for food with other sharks and animals closer to the surface. Overall, sharks live all throughout the oceans, and have many unique features in order for them to
If the shark gets taken out of the water, out of its natural habitat, it will become exposed. Above water the shark will immediately be unable to breath, and it will struggle for air. If taken above the water the shark will not be able to guard itself from the bear’s aggressive attacks, and it will surely lose the fight. Bears might not have the greatest
While it appears likely that different species of sharks would share similarities in their navigational strategies, there will likely be interspecies differences. Since leopard sharks (Triakis semifasciata) were selected in Andrew Nosal’s study, from which much of the experimental setup has been borrowed, it appears that these sharks are the best candidates for this study. While more would certainly be better for statistical analysis, 36 sharks were captured in Nosal’s study, and it can be expected that similar numbers of sharks can be captured for this study.
