There is a higher chance of getting struck by lightning or a vending machine falling on you than getting bitten by a shark. Another factor that goes along with this is that if a person does get bit it is only because the shark is curious and it mistakes you for a fish. Sharks will feel the vibration of you moving around in its lateral line. Sharks strictly feed off of any sea creature not humans, the shark will quickly realize you are not a sea creature when it does bite you and it will most likely go away. The shark myths that exist are all mainly false.
Hammerhead sharks are found in ecosystems in temperate and tropical oceans. They live in these types of oceans, because if it was a colder climate they would die from hypothermia and soon the species would become extinct. These sharks like to stay in schools up to 100 in numbers. The reason they stick together is there is more protection in numbers and they can kill bigger prey like big great white sharks. Next Hammerhead sharks gets there name for its flat shaped head and some people think it is useless to the shark.
There was even “shark tournaments”. This caused a significant decline in their numbers. Another problem with this movie was that they made it seem like sharks are vengeful and will target certain human beings. They also made the sharks in the movie significantly bigger than sharks in real life are and people got this idea that there were “super-killer sharks” out there in the ocean. It sounds pretty ridiculous that humans can be influenced by a movie but even a movie can have a significant affect on some
These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011). Sharks have been apex predators in the ocean for millions of years, however, the populations of sharks have been at risk for years as a result of many different factors. The impact of overfishing on shark populations has risen into the public eye over the recent years due to several documentaries and movies that have been released recently. Sharks are particularly vulnerable to over-exploitation due to their K-selected life strategy, having slow growth rates, long life spans and due to them reaching sexual maturity at relatively late age compared to that of other marine organisms (Stevens et al., 2000). Fisherman fish for sharks in order to get their fins, which is used to make shark fin soup (a delicacy in South-East Asia).
In the eyes of society and the public, sharks are viewed as ruthless killers Millions upon millions are killed every year, and fear is a major contributor. The reality is that sharks are very complex creatures, and should be treated as such. They are an intricate part of the ocean’s ecosystem and the ecosystem would be completely thrown off without them. We need to realize that these creatures are invaluable, and that we must conserve these animals. If we do not realize this reality, we could lose sharks forever.
This evidence helps explain why the shark didn’t come back for more. But it also shows an example of a tiger sharks hunting strategy, which indicates that this shark was doing more than warning her, but wanted her as its next meal. Concluding that although not all sharks are out to kill humans, doesn’t mean there isn’t, which adds on to my belief that the fear of sharks that humans have are very much
146 orcas have died in captivity, and 48 of those orcas have died at SeaWorld. The average person believes that orcas, also known as killer whales, are in captivity for their own well being, or to research their species, but that is false. Killer whales are tortured to do our bidding, for other people's entertainment and greediness. The orca trainers limit their food rations so that they become hungry enough to want the “food treat” after they do the tricks that are force upon them. Orcas do not belong in captivity, they belong in the ocean not in a tank.
The Japanese Sea lion in the 70s, and The Baiji Chinese River Dolphin in 2006 have been victim to our careless actions. Let’s not make sharks the next. World leaders, I am not here to just tell you about the demise of sharks, but to ask you to take action to halt their demise because this problem is on all our hands. As we speak ships are carrying fins to destinations across the world to your country. Currently, there is no international law to prohibit the selling of shark fins.
Orcas with different backgrounds and dialects are placed together without much thought about how this could affect them. A killer whale named Tilikum was placed in Sealand and he was expected to perform tricks that he had never done, and if he performed them incorrectly all of the whales were withheld food. “This annoyed the others, so they would rake him with their teeth, causing him to bleed” (Lewis). In the wild, when a dominant orca begins showing aggression the other orca has thousands of miles to swim away and flee the scene. However, these animals are in pools where they do not have that option.
During the winter, crayfish go to the nether levels of the water, but will come back to the shores during the warmer summer months. “Unfortunately,” says Dr. Sudeep Chandra, a biology professor at the University of Nevada in Reno, “getting rid of the crayfish completely is nearly impossible with our current techniques”. Traps have been used to try and catch some of the crayfish, but nevertheless, only limited amounts have been captured. There have been experiments to find a deterrent for the crayfish. Although some have been discovered, they are too virulent to use near other species.
On SeaWorld’s response they state that these events were accidents, and that the cause of death was not due to the whales, but because of the trainers’ negligence. An example SeaWorld gives of trainer misjudgment, is the incident with trainer John Sillick. On Blackfish we see an orca falling on Mr. Sillick during a show. SeaWorld gives the following response to that event: “Making a poor judgment call based on the routine, Mr. Sillick decided to ride a second perimeter –facing backward -- and took the whale around a second time. This act threw off the timing of the send signal given to the other whale, which performed the behavior exactly as requested, resulting in the accident, not an act of aggression” placing the blame of the incident on the
Also, the lecturer argues that orcas are likely factors in the population decline of the sea otters because of the scarcity of their usual prepay. This left them with no other option but to hunt smaller mammals for food. The reading passage refutes this theory
