Evidence on Prehistoric Sharks One of the previous papers in English class required the class to pick a paper to explore, this question will be concentrated on further in the synthesis essay. What evidence do scientist have to prove that prehistoric sharks existed? The reason behind picking this question wasn’t just to find proof that these monsters swam the seas, but to learn more about them from different resources. One of the resources that were used was a chapter in Angelo Mojetta’s book
It’s also one that’s almost completely misplaced, said George Lauder, the Henry Bryant Bigelow Professor of Ichthyology. Experiments conducted in Lauder’s lab and described in the Feb. 9 issue of the Journal of Experimental Biology reveal that, while sharks’ sandpaperlike skin does allow the animals to swim faster and more efficiently, the surface of swimsuits such as the Speedo Fastskin II has no effect when it comes to reducing drag as swimmers move through the water. “In fact, it’s nothing like
mph and have 3,000 teeth in several rows. You may think a great white shark is massive, but their ancestors would make them look like midgets in comparison. An ancient shark called Megalodon appeared on earth more than 20 million years ago. Based on fossils of their teeth, scientists are estimating that the Megalodon would be the size of a school bus! That’s big enough to feast on whales. The Great white sharks sense of smell is better than a human. A great white shark could smell a drop of blood
CLASSIFICATION Taxonomic words can be difficult to understand. So below are some of the words that classify whale sharks from the underwater world and their definitions. Animalia: a taxonomic kingdom that includes living and extinct animals Chordata: a taxonomic phylum that includes all the animals that have a spinal column (backbone) Chondrichthyes: a class of fish that have cartilaginous skeletons Orectolobiformes: an order of carpet sharks Rhincodontidae: a family of small-toothed sharks Rhincodon
This study observed the standard and routine metabolic rates and swimming activities of nurse sharks. Nurse sharks use buccal pumping to rest on the sea floor. This sedentary behavior had not yet been studied in relation to metabolic rates before this study. This study also is one of few that observed the effcts of temperature on metabolism in sharks. By assessing the relationship between routine metabolism and ecology, a more precise understanding of the nurse sharks daily energy requirements
“21 So God created the great creatures of the sea and every living thing with which the water teems and that moves about in it, according to their kinds” (Genesis 1:21b). God created fish and the great white shark is one of many different kinds of fish. Many people know it as the man eating shark, and some think of it to be fierce and deadly. Well all of these things are true, but people do not know the reason for all of these things and why it is so deadly. The great white is looked at as the most
Why Sharks Attack Humans The ocean is the most magnificent overwhelming sea of blue. The ocean is one of the most undiscovered and mysterious places on earth. The creatures that lie in the beautiful turquoise water are yet to be discovered. New marine life is being discovered all of the time. Some of the creatures that are already well known are deeply feared by humans. Sharks are one of the most feared animals in the world. Sharks are viewed as bloodthirsty, evil beasts of the ocean. Shark attacks
history, we have seen many animals that have lived on Earth and are no longer alive. However, there is a specific species such as the Megalodon, that though once thought to be extinct, has been speculated to still being alive today. Megalodon are gigantic sharks the size of a greyhound bus with teeth the size of the palm of your hand or maybe even bigger. The Megalodon went “extinct” due to the lack of prey because of major changes in the environment around them. The reason why there has been speculation
[Introduction] Sharks are essential to our marine ecosystems, and the continued culling of them can cause the extinction of the species as well as a devastated ecosystem within our oceans. Not only was Jaws the prolific movie that changed Steven Spielberg's career, but it was also the movie that changed the perception of sharks forever. Fear of sharks went up, people stopped going in the water, and shark populations started to plummet. Since the premier of Jaws, shark populations have decreased by
Introduction The Saltwater crocodile, also known as the Crocodylus porosus, The modern organism The saltwater crocodile is currently the largest reptile in the world, having the average length of 4 meters for a female, and 5 meters average for a male. These crocodiles flourish in parts of Southeast Asia, Northern Australia and Eastern India; commonly in rivers and swamps. Grey and brown in color, the animal possesses a firm body, a vigorous tail, a substantial head, excessive jaws and are also
Sharks have lived on Earth for more than 400 million years. There are between 450 and 500 known species of sharks. Sharks are one of the most important species that wander the Earth. They are in charge of keeping the marine ecosystem healthy. Being one of the biggest predators in the sea, sharks have an essential role keeping the food chain organized; making sure species below them don’t exceed in number, or the opposite. By removing the weak and sick of a species, sharks make sure diseases don’t
We absolutely astounded you with our first selections of 25 rare sea creatures in parts one through three, and you have come back seeking more mind-blowing discoveries! We have finally returned with our final part four, bringing you the top nine most incredible species of sea creatures that you never knew existed! Number Nine: The Mola Mola The impressive mola mola is a bony fish known as the world’s heaviest fish species, weighing up to 2,200 pounds. Often called the ocean sunfish, this species
Bear vs. Shark On a level playing field the bear would prevail because it has many weapons to destroy its prey on multiple surfaces, and they instinctually fish to survive. It’s a known fact that bears not only have mighty paws with razor sharp claws attached onto them, but they also have piercing teeth they use to tear apart any opponent. The bear can independently move both of its paws with ease which allows it to attack the shark from multiple directions. Also, the bear could attempt to stab
reproduce, and the difference between Megalodon and the Great White, and why sharks attack. Sharks are one of the top predators. An average shark has 15 rows of teeth in their jaw. The shark that has the most rows of teeth is the Bull Shark. The normal shark size is 15-16 foot, and their main food source is fish. Sharks reproduce in an interesting way. The male shark bites the female for stability, then he uses his claspers to connect to her claspers to transport

the massive jaw and teeth, the Megalodon was able to eat whales by clamping down on the whales body with it's powerful jaws. This powerful impact had the ability of killing the whales almost immediately by crushing their skeleton and crucial organs. There have been remains of a 20 meter baleen whale without it's head, in the same area where there was Megalodon teeth fossils. This suggests that the shark tore off/or ate the whales head showing how powerful the Megalodon truly was, (Sharkopedia,
Sharks now are a lot more dominant than they were before, seeing something put up a fight with a great white is very rare. Most sharks are carnivores and do not seem to have very much competition for food because of their size and ability to hunt. Not all sharks now are at the top of the food chain but for the most part there are not many other creatures that will put up a good fight with a shark. Just like an creature on earth as time goes on something’s are no longer needed and eventually with
madness. Furthermore, Kean ties in manganese to the story through the findings of the shark teeth at the bottom of the ocean. Scientists discovered that manganese covered the surface of the large teeth; and people connected this to the craze of the megalodons. The author also recaps the scandal of Pons and Fleischmann, who claimed to create cold fusion using palladium, a powerful element that is able to consume immense amounts of hydr... ... middle of paper ... ...was really thought-provoking and
