Did you know? angelfish got their name from their pointed fins? angelfish and goblin sharks have different things on their body that tell the differences.
First, angelfish. Angelfish have different colors like black,yellow, blue and orange. Angelish can squeeze into tight object because they are so thin. Young angelfish look different than there parents. According to the text young angelfish are in disguise. Angelfish make a sound like"tzz tzz" to warn other angelfish to get out of their way.
Finally, goblin sharks. Goblin sharks got their name from a japan word tengu-zene. Goblin sharks use their teeth to trap their prey inside their mouth. Goblin sharks have teeth in their body that chew their prey. According to the text a man caught the
The film Sharkwater is a documentary directed and produced by Rob Stewart. Rob is an underwater photographer and a biologist that has a fascination with sharks, and their behavioral aspects. His way of studying these creatures he is able to learn about life and how to survive on this earth. This film showed the characteristics of reflexive documentary, this is because of the attention drawn into the sharks, their behaviors, and how we are affecting them. A statement that really stuck the documentary is people are taught their whole entire lives that sharks are dangerous but when you finally see it underwater your whole life can change in a flash. Rob made a very valid point as well, which is believed to be his thesis statement.
head of a hammer. Their eyes and nostrils are at the ends of the hammer. There
But occasionally the younger sharks are preyed on by bigger sharks that do not necessarily have to be Bull sharks they can be become prey to any larger species of shark and occasionally a crocodile. However there are parasites like Pandarus sinuatus, and Periscopus dentatus that use the surface of the shark’s skin and use it to survive (Curtis). Though that does not in anyway decrease or increase the economic uses for the bull shark, its effects on the environment, or level of danger to humans. In certain places around the world the amount of bull sharks is decreasing slightly, because sharks can be harvested to make fish food, for their meat, for oils, and their fins for shark fin soup, or in asia their skin can be used to make “good leather” (“Bullshark”; Curtis). Even though their numbers are thought to be decreasing according to the International Shark Attack Files, otherwise known as the ISAF, has reported that there have been at least 70 reported unprovoked attacks on humans of which 17 were fatal, but that is only the known number of the reported attacks by bull sharks there most likely have been many more attacks that went unreported (“Bullshark”; Curtis). They are known for being one of “the most dangerous sharks in the world” because they along side the tiger shark,and great white they are the most common sharks to attack a human
The Carcharhinus leucas commonly called the "bull shark" is a very unique shark. The bull shark can live in both salt water and fresh water but is commonly found along the Mississippi River and around Nicaragua. The bull sharks has a very blunt rounded nose giving it a bullish type of appearance thus giving it the name bull shark. The sharks are a dark black to a light grey with a white underbelly. Bull sharks can grow to be about 350 cm long and weigh around 230 kilograms. Bull sharks also tend to have smaller eyes compared to many other sharks which indicates that the bull sharks have limited vision. The bull sharks have triangular teeth like the great white shark (one of the bull sharks cousins). The bulls teeth are heavily serrated and are about 1.5 inches long which makes it easy to tear apart the flesh of their prey.
This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because they mistake surfers for seals. In earlier times, the ocean was a source of mystery and adventur...
How have the filmmakers of The Cove and Blackfish used techniques to generate empathy for animal rights?
In Chinese tradition, Shark fin soup is called as “a celebration soup”, which people eat it to celebrate in various occasions. Moreover, people also believed that shark fin consisted of diverse nutrition values which provide them virility, wealth, and power(Wolchover, 2011). These beliefs lead to the beginning of poaching for sharks, the top of food chain in the sea world. Surprisingly, although people are aware of the decreasing number of sharks since the old days, around hundred million of sharks are still hunted each year(Heltus, 2013), to be served on luxury tables surrounded by those believers in things that they do not even prove whether the belief is reliable. Therefore, in the generation that people are mostly educated, sharks should no longer have to be continuously killed for their fins.
Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
One of the previous papers in English class required the class to pick a paper to explore, this question will be concentrated on further in the synthesis essay. What evidence do scientist have to prove that prehistoric sharks existed? The reason behind picking this question wasn’t just to find proof that these monsters swam the seas, but to learn more about them from different resources. One of the resources that were used was a chapter in Angelo Mojetta’s book Sharks, called “ The Birth Of A Legend”. The other resource that was used for information was an article in Discovery Channels website called “ Prehistoric Sharks”. Sharks and Discovery Channel are the two resources that led to many other questions about their different, and similar views on prehistoric sharks existence.
...arks-world).This means that the bull shark can process freshwater and saltwater by adjusting the amount of sodium and urea it needs.This is important because this feature makes this species very special and separable from other sharks.On the other hand,hammerheads have regular shark anatomy,except for their head and mouth.’’The hammerhead`s mouth is smaller than most other large sharks and can`t open as wide’’(“Hammerhead Shark” 2).This means that everything except for the shark`s head and mouth is regular.
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
The morphology of whale sharks is mostly similar to aquatic fish species, but many specific traits help differentiate them from the rest. Whale sharks are the largest fish in the world and can reach a size of around 20 meters (Martins, C., and C. Knickle). This is often compared to the size of a school bus. The shark has a very large transverse mouth. They have 5 very large gill slits and have a larger first dorsal fin compared to the second one (Whale Shark). They have a distinctive spotted “checkerboard” pattern with stripes (Martins, C., and C. Knickle). It is not exactly known why they have this specific body marking. It is believed that the body markings act as a camouflage. The strange thing about whale sharks is that they have 300 rows of teeth that play no role in feeding (Martins, C., and C. Knickle).
One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in any warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans. The whale shark is a species with a fascinating ecology, life history, behavior, anatomy
