Shark Vs Polar Bear Research Paper

jaw structure. The teeth are actually modified, enlarged placoid scales. The teeth aren’t anchored in the jaw; they are just embedded on the gums. Unfortunately, when the great white shark eats on its prey, it sometimes loses or breaks the tooth by the flesh. Luckily, sharks have developed a special feature that enables it to replace its missing tooth. They have developed rows of teeth, each tooth moving up to replace the missing one. A whole broken row of teeth can be replenished, just like a conveyor belt. Each tooth, though, has a different shape, changing according to its necessity. The great white has triangular, serrated-edged teeth anywhere from one to two inches long. With this feature, the shark is able to tear through the flesh for its meal. The jaw of the shark is made up of strong bone tissue. It must be very powerful because the shark is designed for feeding.

An encounter with a shark is not something that many people really want to experience. The movie Jaws definitely put the fear of the ocean into many people. Sharks have been all over the media lately; Shark Week on the Discovery Channel just ended, and several attacks have been reported over the last few months. However, on a happier note, a beached Great White was saved this weekend in Cape Cod by beachgoers who sympathized with the struggling animal.

They can swim at thirty five miles per hour(Institution, Smithsonian). They also have seven rows of teeth(Institution, Smithsonian). They have a total of three hundred triangular serrated teeth(Bradford). When Great white sharks are in the womb they supposedly swallow their own teeth. The first time they sink their teeth in their prey, it is called a sample bite. Sharks normally go up to their prey and taste them to make sure the want to eat them(Bradford). That's why most attacks are not fatal, because the shark tastes the human and thinks yuck that is not what I want to eat and spits them back out. They don't normally mistake humans for food considering only five to ten happen every year(Bradford). Once they sense food they need to get to it fast. They can swim up to fifteen miles per hour(1). Great Whites have to be fast at Cape Cod because they can not sneak attack the

Differences include the size of legs, ears, noses, paws, claws, jaws and the colour of the bear's fur. Polar bears generally have larger legs, smaller noses and ears, soft paws, short claws and small jaws with strong teeth. These adaptations have occurred to improve the polar bears wellbeing and chance of survival whilst living in the Arctic. Whereas, Brown bears have larger and more claws and a heavier and larger skull (Difference Between, 2014). This is too to help them survive in the environment.

Peter Benchley the author of Jaws said, “Without sharks , you take away the apex predator of the ocean, and you destroy the entire food chain”. My paper’s main idea is how Great White Sharks survive in the ocean. Like how they hunt and how their features help it hunt,hide,and survive.

Polar bears are the top predator in the tundra biome. The polar bear mainly eats seals. Polar bears are the largest land carnivore on earth, their average weight is 990 for males, and 500 for females. Polar bears have white fur, but black skin. The black skin is used to absorb sunlight for warmth, while the white fur is used for camouflage.

Unluckily, after many rescue and first aid attempts to stop the bleeding he passed away at the scene. Most killings triggered by shark incidents are from blood loss as arteries are frequently shattered. The distress and fright the bystanders would’ve sensed that day from the attack would encourage them to believe killing the Great White is the best clarification. ‘This shark has tasted human flesh and will kill again. This ‘rogue’ shark must be hunted down and killed so that our beaches are safe’ (SACE Stage 2 , n.d.). However, as a personal opinion; I believe the Great White Shark should be conserved as there is no real advantage if its shot. The attack itself is such a rare event, it tends to only be one or two bites, and consequently scientists believe it a fault when these incidents/attacks happen. ‘Shark attacks on humans only occur when the shark mistakes us for their normal prey of seals and dolphins and then, realising their mistake, sense us by their bite and spit us out’ another reason why they are attacking us is because us humans are swimming in their environment which they call home and they are just protecting themselves just like we protect ourselves from danger. (SACE Stage 2 ,

The anglerfish and polar bear adapt to very extreme enviorments. The polar bears have to adapt to very  cold weather. The anglerfish have to adapt to the very  little food source they have in the deep sea. They both have devoloped many features that can help them while they live in these extreme enviroments.

When sharks attack, they use many different methods and techniques to attack. Sharks can use sudden attacks which is a fast procedure that Great Whites like to use.

This might be surprising because the great white is smaller it will have more speed. Wrong, the killer whale can swim up to 30 mph. That is really fast for how big the killer whale is and how much it weighs. The great white shark can only swim up to 20 mph. That is 10 mph less than the great white shark. Speed can really change a battle. The killer whale can escape easily when he needs too. Also since the great white shark is slow when it tries to escape it can’t because the killer whale can swim up to him and catch the great white shark. As you can see the great white shark has an advantage in speed. That is my second reason why I think that the killer whale will

Have you ever wondered if a female shark was bigger than a male. Well in this we

Great white sharks are really interesting because of their unique features. One of these features is their teeth. Great white sharks have triangular teeth that are about as sharp as razors. The edges are serrated with a bunch of sharp points on the tips, which are used to eat other animals ( live

After reading both of the stories I found that both the animals the Polar Bear and the Angler fish are Carnivores. They both have a harsh envirorment.Since they are both Carnivores thet dont have to good of a food supply, like if they live in a grassey green place since the only eat meat . They adapted to those harsh envirorments very well by,the anglerfish having to atract fish with the light on there head.Allthough the Polar Bear lives in -50 degrees.But the polar bear has black skin that absorbes the heat and 4 inches of blubber to go with that , the Polar Bear has to lay down in the snow to cool off. The Polar Bear has long strong legs and huge curved claws are especially adapted for striking and killing their prey. Now you know that theese

Its snake like body can reach a length of four meters. Frilled sharks have strong flexible jaws and over 300 sharp teeth to devour other sharks and

There are 465 known species. The Bull Shark is the first most dangerous Sharks. They hunt during the day and night. The eat almost anything. There are a few sharks that can live and hunt in salt water and fresh water and bull sharks is one of them. They can be anywhere between 7 feet to 11 ½ feet long and weight up to 500 pounds. They are found all over the world and swim up to 25 mph. The second most dangerous shark is the Great White Shark. It can be anywhere from 15 feet to 20 feet long and weight 5000 pounds or more. They are found in cool, coastal waters.The 3rd most dangerous shark is the Tiger Shark. They are also known as the garbage can of the sea cause they will eat anything. Females are bigger than males. They
