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
