Sharks

Shark attacks still happen to this day. There’s nothing more terrifying than hearing a story in the news of a mighty, great white shark killing an innocent person. He mentions the backlash of Hollywood blockbusters such as “Jaws” and “Sharknado 3” that intensifies one’s fear. Sharks have evolved in our

Sharks, the scariest, biggest, baddest creatures! That's what we make them out to be, but are they really? The answer is no, we say that. We kill more of them than they kill of us, about 900,094 more. Sharks, being carnivores, are NOT natural predators of humans.

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.

Sharks have been in our oceans for almost 450 million years. Those millions of years of evolution have allowed many different shark species to develop abilities, and to become perfect predators.

Sharks are the top predators. But frankly, they are starting to vanish out of oceans every day. The sharks biggest enemy are humans. Us humans will kill sharks for food. Sometimes people will even take shark teeth and turn them into jewelry. Humans also will cut off the shark’s skin, and turn it into leather. If you find that disturbing, did you know that some individuals will cut out the shark’s liver and make it into a type of medicine?

They are usually found in the Northern Pacific Ocean, ranging as far south as the Sea of Japan and as far north as the Bering straight. It’s believed these sharks spend a majority of their time in epipelagic waters, but individuals have been observed in waters as deep as 660 meters. Salmon sharks are generally about 200-260 centimeters long and weigh around 220 kilograms. They are usually medium grey to black in color with a white underbelly and short, cone-shaped snouts. Overall they have a great resemblance to Great White sharks, hence the nickname “Mini Great Whites”. The primary prey for these sharks is salmon, but they also eat squid, herring, and pollock. Salmon shark are also ovoviviparous, with a litter size of 4-5

Also hey are very unique and interesting. They can get up to 15ft long. Next blue sharks like to move around so they don’t stay in one spot for long. At last watching the movie jaws made people have many opinions that are oncel sharks. People find sharks very threatening but they are just like us.

The problem, or debate, that I have chosen for my final project is the return of White Sharks to the Atlantic coast, specifically off of Eastern Massachusetts. Because it is more of a debate, there are both positives and negatives to this. These pertain to environment and ocean wildlife, public safety, ecotourism, conservation, and research.

The Australian Grey Nurse Shark is also known as the Spotted Ragged-Tooth Shark and as the Sand Tiger Shark ("Australian Threatened Species”). The species is identified by its gray to gray-brown coloration, the possible presence of reddish/brownish spots on the caudal fin and posterior half, their countershading, and by its two almost equally sized dorsal fins. They are known to grow over 3.6 meters in length with the males and females maturing at different lengths, 2.21 meters and 2.2 meters, respectively (McGrouther, 2015). Females also mature significantly later at 9-10 years than their male counterparts, who mature at 6-7 years. Their diet consists of fish,

All sharks are dangerous at one end of there body but the thresher shark is a force to be reckoned with at both ends of its body. With a tail that can swing up to 80 mph the thresher has made this ability its main way to hunt food. These sharks can build surprising speed of about 30mph to catch its prey. By swinging its tail into a

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. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man. Sharks are classified in the order

The black tip reef shark, is also known as the Carcharhinus Melanoperus gets its name from its pointed snout and black tips on the end of each fin. They are considered one of the most beautiful sharks in the whole ocean and are frequently seen by divers. Its average length is 1.9 meters and weighs about 130kg. They live on warm, shallow coral reefs in the pacific, indo and Mediterranean Sea with the deepest depth up to 80 meters. Their proffered water temperature is 15C -24C. These reef sharks are very social and will often be seen in packs or groups with a strong hierarchy system, although they are predators, when they come face to face with another predator they tend to become more shy and timid . Although these sharks are calm most of the time, when hungry they become athletic and energetic hunters, they have a great technique, to launch their whole body out of the surface of the water and roll up to 4 times before falling. They also have perfect pack hunting skills, and will herd a school of fish into the shallows and then feed on them, they can feed on small fish such as herring and sardines, they eat stingrays and smaller sharks. Females are able to reproduce without a male and can give birth up to 10 pups per year, each pup will usually hit maturity at age 4 and most sharks will live until age 13. Conflicts have happened between black tip reef sharks and humans before as we swim so close to them and their habitat, but the rates are exceedingly slow and these sharks would

Tiger sharks are noted for having the widest food spectrum of all sharks. They can eat almost anything, from turtles to birds, as well as other sharks and fish. Besides normal prey they even eat garbage like tires, nails or car license plates, as sometimes documented by examinations of their stomach contents.

Whale sharks usually hang out near the surface where waters range between 21 - 30 degrees celsius ( 70 - 86 degrees fahrenheit ). They usually spend their time in the coastal zones or on reefs. Whale sharks have the ability to dive 1700 meters ( 1.1 mile ). When they dive that far they have to endure temperatures as low as 7.8 degrees

A shark is equivalent to a black widow. You can live with it as long as you don’t cross paths. The basic instinct would be to kill a spider on spot once you see it. The personal instinct when encountering a shark is to get away as possible from it. Both are deadly in their own personal way and at the same time, both have the majority populous disagreeing against them as far as nobody wanting anything to do with them. According to Cindy Watson, “Admittedly, sharks are not cuddly and lovable” (Watson, 2010). This leads us to the “cuddly
