Fifteen years from now I picture myself loading SCUBA gear into an old, beaten up dive boat. I feel

Every Jaws fan knows the shark gets it in the end. What they do not know is that too many sharks have gotten it; and that has caused a rapid decline in the shark population over the past thirty years. Since the 1970's, sharks of the Atlantic and Gulf of Mexico shores have declined eighty-five percent. Sharks are vital animal to our world's ecosystem, and if the decline is not controlled; we could be facing devastating problems in years to come. Information has been obtained from two books: The Shark Almanac by Thomas B. Allen and Sharks, An Introduction for the Amateur Naturalist by Sanford A. Moss. Sources also include a number of online references, among them BBC News, ENS News, The New York Times, and two online scientific

The Eastern Grey Nurse Shark inhabits Australia as a genetically distinct population from its Western counterpart, and has been labeled a “Critically Endangered” animal by the Environment Protection and Biodiversity Conservation Act of 1999 ("Australian Threatened Species”). The population is found along the coast of Queensland and Narooma, the southern area of New South Wales, and various efforts have been put in place to conserve the species (“Grey Nurse Shark,” 2016). As such, the conservation methods put in place are not sufficient and further steps are necessary to allow the species to recover from its human-induced endangerment.

Diving with sharks is a way for people to learn about sharks. According to Ocean Ramsey (2016), a shark and marine conservationist and biologist, the diving experience “covers shark biology and physiology, and how it

The focus of this research paper is to analyze the information, unique characteristics, and history regarding the subculture of scuba divers. Scuba divers get to explore new, exciting, and breathtaking regions in the ocean that many people never get to experience in their whole lives. Scuba divers hold important roles in society because of the discoveries they make on a daily basis. They provide much needed research that is important in the scientific community regarding newly discovered marine species. Scuba divers get the opportunity to explore exceptionally beautiful ocean features that include shipwrecks, coral reefs, and other stunning tropical ocean regions. Many people find scuba diving an enjoyable leisure activity to be involved

Humans have learned an abundance of new things from nature. Such as the echolocation of a bat; to the medicinal properties of the Aloe Vera plant. There is no limit to what we can learn from the world around us. Everyday humans are taught something that can help us thrive. However, some species in nature provide more informative wonders than others. Just as humans discover things from nature, we can observe sharks and learn things we never knew. From hydrodynamics skin to amazing curative abilities as well as constant movement, sharks can teach humans many things.

Did you that sharks are more afraid of us than we are of them.Amazingly sharks can have up to to 3,000 teeth at a time.Some sharks stay in one place when they are little then migrate somewhere else when they get older.Sharks are very unique and interesting sea creatures.This paper will explain low risk,habitat & range,& teeth of a shark.

This highly migratory species is circumglobal in all temperate and tropical seas, with an Atlantic distribution from Newfoundland (Canada) to Norway in northern latitudes down to South Africa and Northern Argentina in the south hemisphere. Known to be the fastest shark in the world and probably one of the most active, this endothermic shark is common in the epipelagic realm (up to 600 m depth) in waters of 17 to 22°C temperature (Compagno 1984, 2001). The mako shark is one of the most important captured shark species for open ocean pelagic fisheries, targeted in commercial tuna and billfish longliners or non-targeted as a bycatch (Ebert and Stehmann 2013). For that reason currently is considered as “Vulnerable” by the IUCN Red List (Cailliet et al. 2009) and is listed on Appendix II of the Convention on the conservation of Migratory Species of Wild Animals (CMS) in 2008 (CMS 2008), a list for Migratory species that would significantly benefit from international

Sharks are one of the oldest living species on planet earth. Their earliest discovered fossils have been dated back to over 420 million years old. Being one of the oldest species alive today, they have undergone significant changes over time. The purpose of my research on these magnificent creatures was to discover exactly why they’ve been able to survive for so long, in contrary to other species that have become extinct. Existing research shows that sharks have been able to survive because of their ability to adapt to different environments. In 2013, a paleontological dig site in southern France yielded fossilized teeth of a tiny shark relative, indicating that the fish escaped catastrophic events by swimming to deeper oceans. This is an example of such adaptations that sharks have

To begin research for this project, I started with One Search. This proved to be one of the better resources that I used. Besides One Search I also used USA.gov, Aquatic Sciences and Fisheries Abstract, Bibliography of Asian Studies Online, and Web of Science. Each of these databases proved to be useful in their own ways. From One Search I moved towards the Aquatic Sciences and Fisheries Abstract (ASFA), the articles that I found in this database were a good starting point to understanding the anatomical and physiological aspects of sharks. As my research progressed I found that the majority of the articles that I had originally found through this database were not relevant to my research question. I was able to focus in my research from “sharks” to “shark finning” and then ultimately “shark finning within East Asian culture”, and as my research question became more focused I was able to find more specific articles that were relevant. Web of Science was also a useful tool to use as well. It was nice being able to take an article that had good information in it and see where else it had been cited. Through this database I was able to find a few more articles that were useful.

There are more than 465 known species of sharks living in our oceans today. Sharks are an apex predator at or near the top of their marine food chains, and they regulate the populations of species below them. Research has shown that massive depletion of sharks has cascading effects throughout the ocean’s

On the other hand, Marine Biologists Ryan Johnson and Alison Kock (2006) observed a group of test subjects leading to a more alerting outcome. According to their findings, “white sharks travel between cage diving sites at Mossel Bay, Gansbaai and False Bay.” (p. 40) The scientists estimate that “at least 5 to 13 percent of sharks travel between cage diving sites on a yearly basis.”(p. 43) This direct change in travel behavior suggests that something in the water attracted sharks to the point where their natural behavior, travel pattern was suppressed. It is unclear what the exact reasons for the change

Because tiger sharks have become such a threat to humans in Hawaii, between 1959 and 1976, 4668 tiger sharks were hunted and killed, but who is to say it is all their fault? Popular movies incorporating shark attacks such as Jaws sent frightened sun bathers running from the ocean, and as every beach lifeguard knows, there’s nothing like a gruesome shark attack to provoke a giant hysteria of public paranoia. Theses shark attacks upon swimmers and surfers off the coast of mainly Hawaii and Florida’s Atlantic coast has left the public seeking and demanding an explanation for the high number of attacks. The truth?

Exploration of the underwater world is fascinating; both from an aesthetic and scientific point of view. One must have a passion for adventure and the knowledge and skills that come with a diving certification. Diving with a Self-Contained Underwater Breathing Apparatus, S.C.U.B.A., remains the ultimate way in which we can experience this wondrous environment and explore the scientific principles behind humans delving into the expanse of the largest unexplored area on our planet. The application of key fundamental tenets of science allows us to venture into a world in which we are, without question, out of our element. The development of modern-day scuba equipment is a compelling one.

Mankind has always been very curious about the ocean and its secrets. In the past centuries, countless numbers of inventions and experiments have been made in an attempt to maximize the time that a person can stay underwater. Thanks to a device called the aqualung, invented in 1943 by Jacques Cousteau, people were able to dive down and explore the ocean with his/her own air source without the need to be connected to an air source at the surface. Eventually, this lead to the formation of a subculture around the sport, with many divers around the world exploring the world’s oceans.

SCUBA diving is a growing, and global recreational sport, with one certification agency, PADI, claiming an “annual average of 900,000 new diver certifications globally”. Of course, not all of these new divers will continue on to become frequent, or repeat divers, however,
