Research Paper On Shark

Sharks have been creatures that can date back to over 450 billion years, and have survived through all disaster and still live on Earth today. This is a great feat for anything to stay in existence for that amount of time, and hopefully sharks can continue to live on this Earth and not go extinct. There are hundreds if not thousands of species of shark from when they first swam Earth’s oceans to when they continue to swim the same oceans. The study of sharks is a very interesting and extraordinary topic, being able to put together images of what sharks used to look like compared to sharks now is just amazing. In this vast amount of time sharks have spent on this Earth there has been many things that has changed, through evolution and adaptation. Through research and personal opinion I plan to show how sharks have evolved, what has changed through evolution and the history of

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 one of the oceans top predators. They vary in size from the extremely small dwarf shark, to the colossal whale shark. Sharks can be found all across the world’s oceans, from the tropic waters of Hawaii to the sub zero temperatures in the Artic oceans. Of the hundreds of sharks a select few species have actually been recorded in the Artic. Of these few, only three of them spend the majority of their time in these harsh, freezing waters. These sharks are the Greenland, Pacific Sleeper, and Salmon sharks.

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

If a bull shark and hammerhead shark were to fight, the bull shark would win. Bull sharks are the most dangerous sharks in the world! Along with this, bull sharks have special adaptations, and they hunt in shallow waters. Although hammerhead sharks have great vision, the shape of their heads, and the placement of their eyes cause them to have a huge blind spot right in the middle of their head. This makes it easier for other sharks to win a fight against the hammerhead.

In John Bauer’s short story, “The Truth About Sharks”, Beth is treated unfairly by the security guard. To begin with, the security guard shouts at Beth due to the misunderstanding about her shoplifting, which caused her to cry and become uncomfortable. As Beth is talking to the security officer, the officer angrily shouts and causes Beth to say “ you’re hurting me!”(133). Beth is treated unfairly because of the misunderstanding due to her shoplifting. She is terrified of the consequences that could happen such as going to jail, losing her son and being charged. Beth is uncertain about her future and the next moments. This situation will drastically change the daily lives of all three characters and put them in uncertainty. Next, Beth is violently

For this discussion, I chose to examine the reproductive nature of mountain lions and hammer head sharks. Mountain lions are solitary cats that live in various mountainous regions of north and south America, but a male and female come together socially in order to mate during the 3-10 day estrus period. Due to their solitary nature, mountain lions rely on scent marking in different territory as well as a mating call of the female in order to initiate the potential for sex. Typically, when a male and female find each other; they spend several days together during the mating period and he may hunt for her and run mating circles around her. Mountain lions are polygynous and both the males and females will mate with multiple individuals throughout

This article talks about what sharks does in order to survive and what are they capable of doing. According to the article, sharks do not sleep; but rather, they have rest periods throughout their day. Sharks are capable of hearing anything below 1000 Hertz and can also swim up to 20 mph. Sharks skeleton is made up of cartilage rather than bone. According to the article, cartilages are lighter than bones. What keep them from floating are their large livers. Sharks can gather and keep the air into their stomach to keep them from floating.

Pacific sleeper sharks, which are also known scavengers, can glide through the water with little body movement and little hydrodynamic noise making them successful predators. They feed by suction and cutting of their prey. They have large mouths that can inhale prey and their teeth cut up any pieces that are too large to swallow. They show a characteristic rolling motion of the head when feeding. Only in Alaska has the shark's diet been studied - most sharks' stomachs contain remains of giant Pacific octopus. They are also known to feed on bottom-dwelling teleost fishes as well as soles, flounders, Alaska pollock, rockfishes, shrimps, hermit crabs, and even marine snails. Larger Pacific sleeper sharks are also found to feed on fast swimming

On ABC’s Good Morning America’s Weekend Adventure special, viewers were taking to new depths of excitement and adventure as tourists went face to face with the beautiful Caribbean Reef Shark off the coast of the Bahamas.

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.

The shark is well known to be feared due to fictional sources such as movies. Reality is different from fiction, but still people continue to overestimate what the shark can do. Sharks are often portrayed as the most gruesome aquatic animals in the sea. In truth, they are not specifically attracted to humans and their ships, but just about anything that’s food to them .The variety of shark species all have one characteristic in common, electroreception.

Imagine the world without sharks. Without sharks the world would be over populated with fish and the ocean wouldn't be the same EVER AGAIN. We should save sharks because they keep fish from being overpopulated and sharks could become extinct.
