Hammerhead Sharks Marine Science/ Per. 1 Sharks are one of the most feared sea animals. They live in oceans across the world but are most common in tropical waters. There are over three hundred fifty species of sharks. They can be broadly categorized into the following four groups: Squalomorphii, Squatinomorphii, Batoidea, and Galeomorphii. The shark family Sphyrnidae that includes the Hammerheads are part of the Galeomorphic classification. They are probably the most easily recognizable of all the sharks.

Their eyes and nostrils are at the ends of the hammer. …show more content…
Sharks generally have a small brain in comparison to their body weight. Among sharks hammerheads have a relatively large brain-body weight ratio. Sharks differ form most other fish in several ways. Sharks have a boneless skeleton made of cartilage that is a tough elastic substance. Most sharks have a rounded body shaped like a torpedo. This shape helps them swim efficiently. Hammerheads are especially good swimmers because of the hydrodynamic function of their head. All sharks are carnivorous. Most eat live fish, including other sharks. Most sharks eat their prey whole, or tear off large chunks of flesh at a time. They also eat dying animals. Hammerheads have definite food preferences. Their elongated head may help them locate the prey they prefer. The Great Hammerhead likes to eat stingrays. This was observed when the stomach contents of a hammerhead were examined and stingray spines were found. Stingrays are usually difficult to detect because they are partially buried in the sediment. Yet, the hammerhead is capable of finding them because they can swim close to the bottom swinging their heads in a wide arc like a metal detector. Sharks reproduce internally. Unlike most fish sharks eggs are fertilized internally. The male shark has two organs called claspers which release sperm into the female where it fertilizes the egg. In many sharks the

As Abraham Lincoln once declared, “Be sure you put your feet in the right place, then stand firm.” Nevertheless, there are many people who embody this quote in our everyday lives and even in literature. In the short story The Truth About Sharks composed by Joan Bauer, it perfectly elucidates such a character.

She also doesn’t have anything she thinks she can wear; therefore, she goes to a department store called Mitchel Gail’s where she finds a pair of black pants she likes. While she enters the store, she passed the sentinel and there was a sign that read, “Shoplifters will be prosecuted to the full extent of the law.” Beth thought that
Nelson Mandela once said “I learned that courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear.” This quote explains how we must overcome our fears to become courageous and brave. Joan Bauers realistic fiction short story “The Truth About Sharks” tells us this. One day a girl named Beth a 17 year old girl woke up to what she thought was just going to be an ordinary day. She had to go to the store and grab pants for a party. Sounds like an simple task, but not for Beth. As she was shopping she left all of her belongings in a changing room and was going to look for a shirt. She told a friendly salesperson named Hanne where she was headed. On the way she was
Terry Tempest William’s written essay, “A Shark in the Mind of One Contemplating Wilderness,” delivers to us, with intended purpose using shocking truths of greed and destruction. Actions took under the cloak and disguise of the needs of civilization, creating more jobs, or even to boost the rich man’s governmental legacy of our badly raped and abused national economy. How continued acts of greed and wanton disregard for the environment, are endangering nature the wilderness areas we have sought to protect? Acts that leave behind damage and destruction where once nature and wilderness thrived.

Many people call sharks beasts, terrible things, killers, but they are not. For instance sharks need to eat to just like humans. Sharks can eat all day. When sharks eat too much they throw it up and eat more. Sharks fend for themselves when they are hungry they might find other sharks and eat them. Sharks eat squid, shrimp, sardines, tuna. Besides sharks can never stop moving so they don't’ stay in one spot. Lastly sharks might look mean but they are

Strategy is not easily defined and furthermore the term is not exclusively related to just the business world. We can confidently say strategy is key to survival, not only in business but also in the animal kingdom. All animals under go a process of constant change in their physical appearance and in their behaviour. These changes take place over millions of years and the species that survive, do so because throughout their evolution they have perfected certain strategies that have enabled them to develop more successfully in the environment they inhabit. One such case of this successful development is the great hammerhead shark.
Killer whales are one of the most fascinating displays of ocean life. The killer whale has characteristics that are important to its survival in the ocean.

Sharks do not have skeletons, but just cartilage. Also their jaws can move independently without any of their other body parts. It allows them to have a stronger hold on their prey. Sharks have oil in their liver that allow them to eat less often. So when they eat us up, they must be really hungry. Their fins help them feel vibrations of other creatures so that they can get into position to pounce on their prey.
Sharks are aquatic creatures and very important to the living with lots of information humans may not understand. To start off, femeles give birth to 7-9 sharks per litter that are 3-4 feet at birth. Next humans believe all sharks are monsters but out of 400 species only 4 sharks have been claimed to attack on humans. Lastly sharks attack for 2 main reasons one reason is for defense and predation. They attack in defense when humans are in or around their territory they attack in predation mistaking people for seals. In conclusion sharks are creatures that humans are still learning about and try to understand them better.
First I will highlight the brief journey through the horror genre and the conventions that have developed. Second, I will then show how these conventions are used in the film Jaws. Let’s start with the silent era, an era based on monsters, Frakingstien 1910, Dracula 1912, The Phantom Of The Opera 1925. Without sound, there was a heavy emphasis on make – up, adding to the horror and preparing the first convention, which is the reveal of the monster. Facial expressions and body language played big part in early horror movies as it provided the tension. A second convention was the ‘dark property in the middle of nowhere,’ using isolation as a way to build up tension.
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.

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.
More and more people have been introduced to a very dangerous practice called shark-finning. Even the people who are aware of the harmful effects they bring still continue on doing it. People are afraid of sharks due to their fierce appearance and the bad publicity they get such as the movies wherein sharks attack humans. Only about 5 people are killed by sharks every year. In fact, vending machines has a higher death rate of 13, while ants can kill about 30 people annually. Sharks are very beneficial to us, why do people keep on harming them?
