I. Introduction In this Paper I will be discussing the physical charcteristics of a great white shark and a Bottlenose dolphin. In other words, a Carcharodon carcharias and a Tursiops Truncatus. I will be comparing the physical charcteristics of both and the subtopics I will be looking at and comparing will be teeth/jaws, eyes(vision), and ears(hearing). II. Background information on a Carcharodon Carcharias. • Its scientific name comes from the Greek words. Charcharrodon (karkardos) meaning rough toothed. Due to the fact the sharks teeth are rough edged and pointy. Charcharias (karkharios) is a name for carnivorous (man-eating) shark. (Castro, 2011) • The white shark is a predator that’s at the top of the food chain, and because it has …show more content…
Tursiops is defined as dolphin like and truncates means the teeth are worn in other words old. (Wells, Eide, etc., 2000) • They are single species and are mostly found in tropical waters. The temperature of water they usually are most comfortable in is in between 10-32°C. However, Bottle nose dolphins can be different depending on where they are located. (Wells, Eide, etc., 2000) • Blubber is very important when it comes to dolphins which also has functions. In bottle nose dolphins the blubber changes seasonally and can also depend on the body size or reproductive state the dolphin is in. two functions blubber has is that it helps protect against predators and also is flexible for bending and act as a spring to help the dolphins swimming ability to rise. (Wells, Eide, etc. 2000) • Their spindle-shaped bodies, muscles, the way they dive using flukes, and the behaviors they use to help keep their energy form swimming all cause the dolphin to be a fast and active swimmer. (Wells, Eide, etc. 2000) • They are the second aquatic mammal that has an auditory system that connects to the acoustic signals throughout the water environment. (Zaitseva, …show more content…
This is relevant to my topics because it talks about the organism Carcharodon Carcharias. Im incorporating this to my paper to talk about the background information about a shark Wilson, B. (2001). Dolphins of the world. Stillwater, MN: Voyageur Press. - The author Ben Wilson did a good job at explaining this topic about the dolphin teeth and eyes and its function and what they do to protect themselves. Also talked about how their teeth help them eat. Its relevant to my topic because it helped me research and find information on my subtopics im going to incorporate this by explaining more in depth the function and characteristics the eyes and teeth have in a dolphin.. Zaitseva, K. A., Korolev, V. I., & Akhi, A. V. (2013). Passive hearing stability in the bottlenose dolphin Tursiops truncatus to low frequency noise spectrum deformation. Journal of Evolutionary Biochemistry and Physiology, 49(3), 353-359. doi:10.1134/s0022093013030109 ν The author did a great job in writing this book he helped me understand and also explained the functions and structures of a bottlenose dolphin. This reference is relevant to my topic because it talks about bottlenose dolphins. Im incorporating this reference into my paper by writing the background information on the bottle nose
Bottlenose Dolphins are a very interesting animal. They have a fusiform (Spindle shaped) body that allows them to move quickly in the water. Because of the Dolphins’ shape they have bilateral symmetry. They also have a dorsal fin, flippers, and a fluke. However, Bottlenose Dolphins do not have ears on the outside of their bodies, hair, or hind limbs. The color of this type of dolphin is usually a light grey color to a black. Their stomach is white and sometimes has a pink hue. One physical adaptation these dolphins have is a telescoped skull. The skull is like this because it allows them to breathe more easily while swimming. Bottlenose Dolphins also have blubber that they use as insulation and vascular shunts that allow them to have cooling for certain types of organs and tissues in their bodies. Finally, Bottlenose Dolphins have sharp teeth that let them grasp onto their prey, so their tongue can push the prey down the dolphin’s throat. Bottlenose Dolphins have a range mass of 260 to 500kg which is 572.69 to 1101.32 in pounds. The average mass of the Bottlenose Dolphin is 400kg. Their average mass in pounds is 881.06.
Transition: After learning about a dolphin’s sense of communication, we can now build upon this information by examining their unique behavior.
In addition to this nature, they are capable of advanced communication skills that allow them to teach new tactics they have learned to their fellow dolphins. I am also the same as a Bottlenose Dolphin when it comes to efficient communication skills.. My style of learning requires me to go through an exhaustive process of trial and error until I have efficiently learned what I have desired to learn. With the knowledge that I have gained, I have been able to ascend to higher levels of academic studies with the ability to use my acquired thinking and comprehension skills which help to aid me in everyday life. However, I am not one to hoard any information that I have managed to learn. I will share any knowledge that I know with my fellow peers around me so that I may aid them throughout life just like a Bottlenose
The features of a Great White Sharks are really interesting like their skin patterns. Their skin patterns help them camouflage in the water. The top of their body is blue to blend in the water. The bottom of the body is grey to blend in with the black color on the bottom of the ocean. The teeth of Great White Sharks are interesting. They have multiple rows of teeth. Their teeth are triangled shaped and have
Although some people think that dolphins are fishes, because they live in the water, they are mammals. They have the same characteristics that we have, they nurse, they deliver live birth, they have warm blood and they have hair.

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.
In the modern world it is known by many people that over the course of Earth's existence it has changed dramatically. This also applies to the creatures that inhabit Earth, they have all evolved over the course of their existence. Sharks have been roaming the earth for over 450 million years, in this extensive time period, there have been many things that have changed since modern day. There are many different reasons on why the evolved, and also how sharks managed to completely change themselves in the course of 450 million years. The life for a shark millions of years ago is going to be a lot different than if they were in the modern world, and this goes for all creatures on earth, because they evolve and adapt to the constant changing world. There are many different traits in sharks right now than there were myrietes ago. Humans have only been in contact with sharks for a tiny part of their existence but have had a huge impact on the way they act
There is something about dolphins that fascinates me. They are some of the most intelligent and beautiful animals that I have ever seen. Their faces are so cute that every time I look at a dolphin it looks like it is smiling at me and wants to tell me something. The noises they make represent some kind of language and it makes me wonder if they can really communicate. I also want to know what kind of feeling they have and whether they have emotions. This is why I chose to do this I-search project on dolphins; the different kinds of dolphins there are, the places that they can be found and their mental abilities.
In the deep, dark, spooky ocean lives a gut-wrenching and petrifying great white shark. This monster of the deep swims menacingly in search for its prey and devours its meal without leaving a single scrap of morsel. Then, there is the pilot fish, the great white’s dependable companion, who works as its dentist. The pilot fish will swim into the mouth of the shark and clean its enormous jaws from harmful parasites. In return, the great white shark will provide the pilot fish with food and protection from its predators.
Dolphins have been around a lot longer than humans. They originated about 50 million years ago. The most common dolphin, being the bottlenose dolphin, has been around for 15 million years. Surprisingly, dolphins originated from members of the cetaceans group. Cetaceans used to be land mammals but evolved into being aquatic mammals. In From Land to Water it stated, “The transition from land to water is documented by a series of intermediate fossils from India and Pakistan.” This research helps prove how they used to be land mammals but evolved to live in the ocean. Dolphins are one out of many aquatic mammals who need oxygen, but they need water in order to live. Believe it or not, dolphins are somewhat related to hippos, camels, deer, cattle, and giraffes. In From Land to Water, “ Many features that are
Dolphins also have the intelligence to save and help humans when they are in danger. About 65 million years ago the ancestor of a dolphin was called a Mesonyx it was a mammal that had lived on land and would feed from the water. Over time, as the habitat and climate was changing they started to get closer to the water. They started to lose their limbs and hair because of the cold water. Todays dolphins still have the structure of pectoral fins is a remnant life on
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.
Bottlenose dolphins are one of thirty-two species of marine dolphins (World Book 297). Their scientific name is Tursiops Truncatus. Males are usually longer and heavier than females. Bottlenose dolphins can grow to be thirteen feet long and weigh up to 600 pounds (Bottlenose Dolphins). This makes bottlenose dolphins the largest of the beaked
jaw structure. The teeth are actually modified, enlarged placoid scales. The teeth aren’t anchored in the jaw; they are just embedded on the gums. Unfortunately, when the great white shark eats on its prey, it sometimes loses or breaks the tooth by the flesh. Luckily, sharks have developed a special feature that enables it to replace its missing tooth. They have developed rows of teeth, each tooth moving up to replace the missing one. A whole broken row of teeth can be replenished, just like a conveyor belt. Each tooth, though, has a different shape, changing according to its necessity. The great white has triangular, serrated-edged teeth anywhere from one to two inches long. With this feature, the shark is able to tear through the flesh for its meal. The jaw of the shark is made up of strong bone tissue. It must be very powerful because the shark is designed for feeding.
