Great Hammerhead Shark Migration Essay

Many animals migrate for different reasons. Ducks migrate to warmer weather when the seasons change. Humpback Whales migrate to follow their food source krill. The Great Hammerhead was known to have movements, but it was not-believed that the movement was in patterns like a yearly migration of most animals that migrate. The Great Hammerhead shark is a large shark and can grow up to 20 feet and weigh in at over 1,000 pounds. Until Recently it was unknown if the Great Hammerhead Shark migrated.

Strategy is not easily defined and furthermore the term is not exclusively related to just the business world. We can confidently say strategy is key to survival, not only in business but also in the animal kingdom. All animals under go a process of constant change in their physical appearance and in their behaviour. These changes take place over millions of years and the species that survive, do so because throughout their evolution they have perfected certain strategies that have enabled them to develop more successfully in the environment they inhabit. One such case of this successful development is the great hammerhead shark.

Both evolutionary and functional explanations of physiology and behavior are important in understanding why certain genes evolve across various generations. The evolution of structural characteristics and behaviors explain many of the questions often asked as to why humans, as well as other species, are the way that they are. More specifically, evolutionary psychologists use adaptive theories to comprehend why particular behaviors are promoted across generations or cultures, while others are not. Both structural and behavioral advantages managed to the survival rates in countless populations, at least in ancestral times (Kalat, 2013). However, while current evolutionary trends are no longer focused on just the adaptations relating to survival,

Due to the biological and ecological characteristics of sharks, they present an array of issues and challenges for fishery management and conservation. Many shark species are characterized by relatively late maturity, have slow growth and low reproductive rates (as they are Apex Predators), which can make them extremely vulnerable to overexploitation. Concern has grown over the past few years regarding the status of shark stocks and the sustainability of their numbers in the world of fisheries. As the demand for shark products such as shark fin soup increases, the number of shark’s species begin to decline as a result of the current trend.

Sharks are creatures that terrifying millions of people around the world. Through movies and the media, they have been made out to be man-eating machines with only one purpose, to eat every last human being on the planet. Every time someone is attacked by a shark the media cries wolf and makes these beautiful animals out to be killers. The reality is that we as a society fear what we do not completely understand. We know very little about sharks compared to other species. Therefore, they make for an easy target to place blame upon. What many people do not realize is that sharks are extraordinary and diverse organisms, able to survive and thrive in many ecosystems.

Conservationists across the globe have presented the notion that sharks are worth more alive than dead, because of the economic growth that shark ecotourism brings in. “The study

I wrote this hoping to get people more interested in one of the world’s most fascinating creatures, the bull shark. I hope this research helps you learn about their migration,eating habits and body features. In conclusion I hope to get more people to research bull sharks and learn more about how great of creatures they

The Western Australian population like many others view sharks with trepidation and fear (Boissonneault, 2011). This is due in part to the media, which portrays sharks as a fierce and deadly adversary to the human race (Boissonneault, 2011). In response to the apparent increase in fatal shark attacks on their population, the Western Australian government has implemented the use of baited drum lines along some popular beaches (McCagh, Sneddon and Blache, 2015). This decision to increase the organised culling of the shark population in Western Australia can be attributed to the government’s fear of losing the faith and vote of confidence from the community whom they serve (Neff, 2012). There are many factors to consider when looking at the main

Recently Australia has been under the national and international spotlight regarding methods implemented to reduce tiger, great white and bull sharks numbers in an attempt to minimise human fatalities. Although relatively infrequent, shark attacks attract a high level of public and media interest, as they invoke a dramatic emotional response. Australia is well known for its beach culture, due mostly to its approximate 11, 800 beaches and estimated 35, 000km of coastline.35 000 km of coast. Given that Australia has a mostly favourable climate, and a range of popular beach and water-related activities, it is not surprising that it has a relatively high rate of shark attack. Data from the Australian Shark Attack File were examined

The extinction of shark is one of the most significant problems that people need to pay attention on in this century. Shack hunting is a very cruel process. Instead of taking the entire shark out from the sea, fishermen would only cut the fin part off from the shark (because this part have the biggest value) (see figure 2) (Fairclough, 2015). After finned the shark will be though back to ocean without any further treatment. And soon after, they will be bleeding to death. The shark hunt is so popular worldwide because it could create large economy value. As reported by Melissa Gaskill, for each year, the global shark catches is approximately about $630 million. Moreover, the benefits of ecotourism is predicated grow to $780 million in the next

To be able to educate our customers, I went through a lot of training and got to learn a lot about the horrendous act of Shark Finning. Shark finning is an extremely cruel practice that is slaughtering sharks by the millions. Not only is this extremely cruel, but it is posing serious threats on the environment. Many shark species are nearing extinction due to the excessive poaching of the animals. There are many factors standing in the way of banning the shark fin trade such as lack of education due to inaccurate media representations of sharks, misled conceptions of fin purpose, and even government corruption and conspiracy in the trade. Sharks play a crucial role in maintaining and balancing our ecosystem and without them in the picture; it could be detrimental to the health of the planet and all who inhabit it. Saving the sharks and banning the trade of their fins is crucial in saving the

The extinction of sharks are causing inconsistency to the marine ecosystem. In 2005 the Mexican and United States research team studied that “ecology of coral reefs dies within one year after all sharks in it were killed.” As finning proceed in various areas, tossing back the rest of the shark’s body into the ocean without their fins is an wasteful practice. In addition, not only do we harm sharks, we are also harming the environment. Other factors of pollution includes oil spills, plastic trash and chemical wastes. Sharks plays a big part in the ecosystem by maintaining the marine life. Sharks help “keep populations of other fish healthy and in proper proportion for their ecosystem (WildAid n.p.).” Without sharks, the ocean can be vulnerable

Environmental scientists look for ways to better our world and protect our ecosystem from human destruction. Debate on the regulation of species, climate change, and how to lower emissions, are all things that environmental scientists look at. One of the most recent crisis’, is a problem not within the US, but takes place in China and other parts of Asia, a practice called shark finning. This is where sharks are captured, have their fins removed for food, and then are thrown back into the ocean, alive, to sink and die. The people of China use these fins for food and other medical reasons. Since the process of finning sharks is so easy, the people of China are able to kill them off very quickly.

Since the creation of Jaws, the fear of sharks has increased rapidly. Because of this fear, the amount of sharks being killed per year has greatly increased. Since 1975, the U.S shark catch has risen from 148 tons to over 8,765 tons. More than one hundred million sharks are killed per year. Sharks attack about nineteen times per year and only kill about one person every two years (Preston, 1995). Saving the sharks is not an easy task. Unlike dolphins and turtles, who are also endangered, sharks are not cuddly cute creatures and are not generally appealing. It is hard to get a population behind a cause that they don’t understand. Sharks, to society, are the mean, mindless, vicious creatures portrayed by the media and old-wives tales and because of this, people don’t care whether or not they get killed.

Most of the stuff we see on there is 50% true but of their techniques of hunting Sharks also hunt in groups to go hunting known has ‘Schools’ which is also is almost 100 sharks hunting in one area, they do this to “Practice using stealth and ambush tactics to catch their prey.” Sharks have a cycle or schedule to go hunting, the time when their prey is wandering around, and also when to migrate to other area. In other words sharks have like a clock in their brain to help them keep track of time. Similar to schools, sharks go on frienzies which means they gang up on a big animal like a big sea lion or a big whale. Ever wonder how the shark’s prey don’t detect the shark? Sharks have the ability to camouflage with sand to sneak attack their prey in an
