Sharks are the most dangerous and aggressive predators in open waters, sea or ocean. Sharks are at the top of the food web and no one or one thing including humans, can dominate sharks in their ultimate domicile. The most aggressive sharks of all are the great white sharks, bull sharks, tiger sharks. The teeth of these shark are extreme acute and their bite force is tenacious. The strongest bite force is from the bull sharks it’s so strong because of their size and shape. Sharks have almost 40-45 on the bottom of their mouth. Researchers have said that sharks teeth are on their gums. Sharks lose one tooth every week. What’s really interesting is that sharks are born with a set of teeth. Great white sharks have soft material on their teeth …show more content…
Like the bull shark, the tiger shark has a voracious appetite for almost anything. This shark will eat anything from its’ normal prey to objects such as tires, nails, license plates, baseballs, oil cans, tin cans, tires, garbage including food waste, clothing and even coal. They will eat large/small marine animals like hurt whales, fish, turtles, even other sharks. They even eat dogongs. They also have excellent eyesight; they are very fast, extremely aggressive in pursuit for prey, and have a strong sense of smell. Also, when tiger sharks are in pursuit for prey, they will gobble down anything in its way, especially garbage (Weebly Homepage). Unlike most sharks, bull sharks can survive in fresh water for long periods of time. They have even been found in the Mississippi and Amazon Rivers. They prefer shallow coastal water, which means that they come into contact with humans more often (National Wildlife Federation). With this notion in mind, humans are much more exceptive to becoming the bull sharks’ main dinner course. Therefore, it is imperative to know what is lurking in the muddy waters before planning recreational
But occasionally the younger sharks are preyed on by bigger sharks that do not necessarily have to be Bull sharks they can be become prey to any larger species of shark and occasionally a crocodile. However there are parasites like Pandarus sinuatus, and Periscopus dentatus that use the surface of the shark’s skin and use it to survive (Curtis). Though that does not in anyway decrease or increase the economic uses for the bull shark, its effects on the environment, or level of danger to humans. In certain places around the world the amount of bull sharks is decreasing slightly, because sharks can be harvested to make fish food, for their meat, for oils, and their fins for shark fin soup, or in asia their skin can be used to make “good leather” (“Bullshark”; Curtis). Even though their numbers are thought to be decreasing according to the International Shark Attack Files, otherwise known as the ISAF, has reported that there have been at least 70 reported unprovoked attacks on humans of which 17 were fatal, but that is only the known number of the reported attacks by bull sharks there most likely have been many more attacks that went unreported (“Bullshark”; Curtis). They are known for being one of “the most dangerous sharks in the world” because they along side the tiger shark,and great white they are the most common sharks to attack a human
The Carcharhinus leucas commonly called the "bull shark" is a very unique shark. The bull shark can live in both salt water and fresh water but is commonly found along the Mississippi River and around Nicaragua. The bull sharks has a very blunt rounded nose giving it a bullish type of appearance thus giving it the name bull shark. The sharks are a dark black to a light grey with a white underbelly. Bull sharks can grow to be about 350 cm long and weigh around 230 kilograms. Bull sharks also tend to have smaller eyes compared to many other sharks which indicates that the bull sharks have limited vision. The bull sharks have triangular teeth like the great white shark (one of the bull sharks cousins). The bulls teeth are heavily serrated and are about 1.5 inches long which makes it easy to tear apart the flesh of their prey.
It is not hard to think of the Great White Shark as one of the most feared animals
On average they weigh 4,000-7,000 pounds and grow approximately 16-20 feet long ( Great white sharks 1). < commentary needed>Great Whites are the apex predator of the ocean containing 300 serrated teeth and highly-developed senses to hunt prey. Sharks have a great senses of smell, the Great White can smell a drop of blood thousand of miles away. They’re hearing is very powerful , being able to hear the vibrations of prey distances of about 800 ft away and find the exact location through ‘ear stone’( Great white 3). A shark 's sense of hearing truly shows their uniqueness as an apex predator. In addition to great hearing they’re known to have great sight by being able to see up to 50ft away and transition into seeing in light and dark. Additionally sharks have a lateral line on their back that reaches from the front to the back tail, allowing
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.
In Chinese tradition, Shark fin soup is called as “a celebration soup”, which people eat it to celebrate in various occasions. Moreover, people also believed that shark fin consisted of diverse nutrition values which provide them virility, wealth, and power(Wolchover, 2011). These beliefs lead to the beginning of poaching for sharks, the top of food chain in the sea world. Surprisingly, although people are aware of the decreasing number of sharks since the old days, around hundred million of sharks are still hunted each year(Heltus, 2013), to be served on luxury tables surrounded by those believers in things that they do not even prove whether the belief is reliable. Therefore, in the generation that people are mostly educated, sharks should no longer have to be continuously killed for their fins.
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.
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
The morphology of whale sharks is mostly similar to aquatic fish species, but many specific traits help differentiate them from the rest. Whale sharks are the largest fish in the world and can reach a size of around 20 meters (Martins, C., and C. Knickle). This is often compared to the size of a school bus. The shark has a very large transverse mouth. They have 5 very large gill slits and have a larger first dorsal fin compared to the second one (Whale Shark). They have a distinctive spotted “checkerboard” pattern with stripes (Martins, C., and C. Knickle). It is not exactly known why they have this specific body marking. It is believed that the body markings act as a camouflage. The strange thing about whale sharks is that they have 300 rows of teeth that play no role in feeding (Martins, C., and C. Knickle).
The bull shark is one of the terrible sharks. They weigh about 110 pound and 11.5 feet. It usually lives in America and it has 350 teeth. It has 7 rows of teeth and 7 teeth in each row. It is also called the zambezi fish and lives in shallow water. They will usually eat small fish and it can eat
To begin with, Tiger Sharks are named for the dark, vertical, stripes found mainly on juveniles. As they grow older, their stripes begin to fade Also, they are man eaters. Tiger Sharks have sharp teeth and very powerful jaws so they will decimate anything they encounter, even plastic bags and cigarette packets! Finally, Tiger Sharks live in tropical/subtropical oceans. In conclusion, Tiger Sharks are very fascinating creatures Jax is one of the many sharks that have been tagged by Ocearch to help society learn about them.
When most people think of sharks, a scenario pops in their head. A huge, creature, with monstrous teeth swimming directly at them, in the depths of the ocean, with its mouth open, about to sink its jaws right into their body. People`s fears of shark are heightened because of what is shown in the media and reports, but in reality, sharks show little to no threat to humans. People have the misconception that all sharks are huge with big teeth and want to eat them. Little is actually known about the diversity of one of the most feared creatures that roam the sea.
Introduction 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 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.
