How does shark hunt
"Shark" is a creature of the things we want to see.In fact, the sharks are not as ferocious animals. The shark is an organism that can survive a day without eating, have just 1-2% of the weight itself. Sharks can not see much detail, but can be seen in the relatively. It saw colour images, and very sensitive to the perception of sound. The cells that resemble a feather in your ear, it will act to change the system can signal the brain.
The shark first occurred about 400 million years ago by the year 2540 Mr.Richard Cloutier of Quebec, Canada, biologists have unearthed the fossil of a prehistoric shark the world. The average length of about 40 meters, but today found that sharks have an average length of just 0.15 meters

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.
Although we are the sharks biggest enemy, some humans largest fear are sharks. But what we don’t realize is that most sharks really are not all that harmful. We sometimes fear sharks because of the shark attacks we hear about on the news, and that we see in the movies. Some say that a shark bite feels the
Arising over 350 million years ago, the shark species has been labeled as a human devourer. Now, with the increase in human population, the demand for shark meat, fins, and cartilage are at an all time high; therefore, the existence of the shark is becoming a concern (Budker 1971). Individuals are conditioned to think of sharks as a negative aspect to the environment, which is prolonging the effort to save shark species from becoming extinct. With that in mind, some private as well as national organizations have accepted the challenge of educating and informing people about the existence of the shark specie and its importance to the sea.
This organism causes the sharks to go blind. Luckily Greenland sharks are mainly scaevngers and heavily rely on their heighted sense of smell.
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 have been in existence for more than 300 million years. Their evolution occurred over 150 million years earlier than that of the dinosaurs. Most of the existing fossil data of early sharks was collected from fossilized teeth together with several skin impressions. primitive sharks (Cladodonts) , had teeth which were double-pointed, up to 2metres in length, ate fish as well as crustaceans, and existed approximately 360 million years ago.
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.
this information widely collides with what the movie the shallows heading place. in the documentary the shark that was proven to kill the most was the bull shark which in history is said to be very territorial, there was one incident where a man was swimming in an area where a bull shark was around and as it bit him once giving him only a few seconds to be aware the shark Came back and took off his arm. this Behavior was set to be shown in a bull shark and not a great white or in the movie the shallows the great white was killing for no reason and yet having a ginormous that well avoiding that well just to
Sharks are some of the world's most dangerous and efficient predators, known for dominating the oceans for millions of years. Thanks to movie classics like Jaws they are often exclusively perceived as large, powerful, killing machines, but the truth is sharks come in a wide range of shapes and sizes. Recently, scientists found the carcass of what's considered the smallest shark in the world. The distinctive “pocket shark” was discovered off the Gulf Coast, and is the second specimen ever found.
In “What do you know about sharks?” by Sharon Guynup and “Great White Sharks” by Peter Benchley the clique thought of the “anthropophagous”, savage, and villainous shark is turned on its head. The two articles take widely accepted myths and debunk them with facts. Evidence that supports that the fish aren’t the vicious marine people-eaters that the media has depicted them as has been found. In this text the findings on the animal will be explored. This is the shark’s Real Bite.
A shark has multiple rows of teeth. The mouth of sharks is in the front of the head. In some species, sharks teeth are replaced as much as once a week. Some sharks have teeth used to crush and grind. These are some what like what humans have. They also have sharp teeth. These can be compared to incisors that humans have. These types of teeth are very important to sharks because they are carnivores and depend on their teeth in order to eat their prey. A sharks body in covered by scales which cover their bodies. These scales make the skin of a shark very rough and strong.
