To begin with, great white sharks are mythical beasts and are fascinating.To start with, the ecosystem that sharks live in is the Pacific ocean or seas all around the world. When sharks attack they don’t want to eat humans but might mistake us for wounded seals which is their main food source. Next, after sharks give birth they leave their young. However, once they do leave they could get killed by other sharks or killer whales. But once they grow up, they can grow to be about 24 feet.
Our fear towards them has prevented a lot of our studies because many people fear that the great white sharks will not hesitate to attack them. But there is actually some vital statistics that have been observed. The great white can grow to 21 feet, but on average are around 13-17 feet long (Smith). Although accounts have been record of larger great whites, some reaching over 30 feet, which is very rare, but they have been reported. None of these though have been officially investigated or tagged. They can weigh up to 2,400 pounds when they have enough food to eat and are thriving in their natural environment (Bio Expedition). You would think this would make for a slow swim speed, but in reality these amazing creatures can reach incredible speeds of up to 15 miles per hour, which is incredibly fast for a shark this large (Smith). In fact, in South Africa the more hostile sharks have been observed jumping five to fifteen feet out of the water in search of catching the seals that swim there, when sharks do this it’s called
A shark can be defined as a marine fish that has rough greyish skin and a skeleton made of cartilage, which usually prey on other animals and are sometimes dangerous to people (Merriam-Webster, 2011). The most tragic shark attack towards humans in history occurred with the sinking of the USS Indianapolis (Nelson, 2002). According to Discovery Channels Ocean of Fear (2012), three specific sharks are responsible for the USS Indianapolis nightmare. Sharks have been known to attack humans, although it is rare and they do not usually initiate attacks.
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.
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
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.
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.
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
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
Despite their belief that the each island had a shark god, the ancient Hawaiians still hunted sharks. Shark teeth are exceptionally good for making arrows and weapons. The meat was eaten, and shark skin was transformed into the top of drums. Today, shark hunting is still legal as long as it is done in federal waters and according to the current regulations.
the black tip shark has a very pointy nose in fact more pointy than any other sharks it uses a chemical odor to attract a mate near by.
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 ,
Great White Sharks have known to be a great source of fear throughout the numerous ages of sea exploration. With an average size of fifteen feet in length, it’s not hard to imagine why. They are the stuff of many nightmares, but they are largely misunderstood. There isn’t a lot of information on Great White behavior because many believe them to be an endangered species, due to dwindling food sources and overfishing. However, with conservation efforts, their numbers should rise and more studies can be done. The latest major discovery was just in 2014, which shows that with time, we can learn even more about them. In this paper I will study the sharks’ basic facts, their various behaviors, and the effect humans have on them.
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
