Introduction The grey nurse shark belongs to the Odontaspididae family and inhabits the marine ecosystem. The grey nurse shark is a keystone species, meaning it’s a species which plays a crucial role in the way an ecosystem functions, without a keystone species, an ecosystem would be dramatically different (National Geographic. 2016). As the Grey Nurse Shark is an endangered keystone species applications and limitations are required through scientific knowledge and understanding to develop solutions

I will never forget the first time I went snorkeling, it was something I had been afraid to do up until the moment I touched the water. Beforehand all I could think about was what if I got attacked by a shark? I was too young to die and I felt like I was tempting fate. Then once I made the plunge into the water everything washed away, as if the waves carried the fear with them as they folded over me. I remember that day so clearly, rocking back and forth, up and down, I sat on a small glass bottom
Both sharks and dolphins give birth to live young, but sharks don 't care for their young while dolphins do. Sharks breathe using gills and flow-through breathing while dolphins breathe through a blowhole. One of the most noticeable differences between sharks and dolphins is sharks have vertical tail fins where dolphins have horizontal tail flukes. Dolphins are warm blooded and regulate their body temperature, where sharks are cold-blooded and their body temperature
A tale of mistaken identity: the ragged tooth shark (Carcharias taurus, Rafinesque 1810) and the story behind a misunderstood creature T.

There’s a shark in the water!” Possibly one of the scariest phrases you will ever encounter when out on the beach for a tan or walk. That fearsome predator that has got
Shark scales, or dentricles, are roughened and will scrape if felt to wrong way, much like sandpaper. The true purpose for this is unknown, although it is thought the shape increases streamlined properties. Sharks have two pairs of fins and four singular fins, all of which are used for swimming or balance. The rear pelvic fins in males are lengthened to aid in reproduction. The oil in the shark’s liver adds buoyancy, due to the lack of a swim bladder. The gills are protected by gill arches and slits
Leaving a legacy There once was a person with a legacy of hurting others in his past and let many people down. After which, he went through a life changing program, and ended up becoming a nurse and righting the wrongs that he caused in his past. He then became a very caring person that many people know of, but don’t know personally. He didn’t want to be recognized by name or by awards for which he received for his part in helping others. He hurt many people and he felt like he needed to make up
INTRODUCTION Although sharks belong to the class Chondrichtyes, there are many different types. Sharks arose about 350 million years ago and have remained virtually unchanged for the past 70 million years and still comprise a dominant group. It is thought that sharks almost certainly evolved from placoderms, a group of primitive jawed fishes. It took a long series of successful and unsuccessful mutations with fin, jaw positions etc to give us all the different designs of sharks around today. When asked
hundred million sharks are killed by humans each year. This is due to hunting sharks for food and trade. As the demand for shark fins, teeth and skin has increased, so has the mortality of these exotic creatures. Popular movies such as “Jaws” and “The Meg” have made sharks feared as monsters by the general public. . An article written by Susannah Bragg McCullough stated, “This is the one adverse, really negative thing that came out of Jaws: ever since this movie came out, shark-killing contests
and swimming activities of nurse sharks. Nurse sharks use buccal pumping to rest on the sea floor. This sedentary behavior had not yet been studied in relation to metabolic rates before this study. This study also is one of few that observed the effcts of temperature on metabolism in sharks. By assessing the relationship between routine metabolism and ecology, a more precise understanding of the nurse sharks daily energy requirements could be obtained. Nurse sharks were caught in the Florida
WHAT IS SHARK CULLING Shark culling is killing large sharks that may be dangerous to swimmers on the beach. The Great white shark has been protected in Australian waters since 1998. So, what changed? Since August 2010, 15 people have been killed and 51 have been injured in 2012. This put pressure on State Governments and so, drum lines were placed in the water and shark nets surrounded beaches. DOES SHARK CULLING WORK? These sharks are killed with drumlines and shark nets. The drum lines lure large
psychopath. As the narrator is fishing in a canoe, two Americans and a local guide pull up in their power boat proudly flying the Stars and Stripes fore and aft, rocking the canoe. During the conversation in which one of the Americans is "friendly as a shark", the other American throws his cigar in the water and threatens to take his business elsewhere (66). Of the Americans, the narrator comments, "if they don't get anything in fifteen minutes they'll blast off and scream around the lake in their souped-up
I shouldn't have gone out so far fish”(Hemingway 110). Santiago is truly sorry that he had to go out so far into the water and catch the giant fish. Because he went out so far, the sharks ate the fish on the way back to the port. He did not want his fish to be ripped and eaten by Santiago's worst enemy, the sharks. He wished it were only a dream so that the fish would not have to go through the pain. This example shows how mush he cared for the fish and how his relationship with the fish was affected
archaic sharks and plesiosaurs. In my research, the Oceans of Kansas organization for Paleontology has given me more than enough to focus on when depicting out how to correlate our modern logic about how Kansas is mostly a wasteland to when it used to be an ocean with striving life within. The sharks that have been recently discovered are increasing not only in size, but by type. Mike Everhart, lead Paleontologist of this organization, in April 2002 discovered an extremely large shark called
Sharks kill an average of about 12 humans per year. Humans kill an average of about 11,417 sharks per hour. Unfortunately, that number may not stop growing unless action is taken. Shark slaughter is becoming an ever expanding issue that could have devastating effects if it is not stopped. As a result of a tremendous increase of demand in shark fins in recent years, sharks are being finned and thrown back into the water where they are left to suffer an excruciating death which can take days to occur
Santiago had the obstacle of beating away multiple sharks while they sunk their teeth into Santiago’s goal. This shows that Hemingway uses symbolism to convey the idea that one must overcome obstacles before accomplishing their goals. During Old Man and the Sea, Santiago not only has to put up a fight with the marlin but sharks as well. Awhile after Santiago had reeled in the marlin, sharks start to trace the blood trail it had left behind. As the sharks got closer to his boat, Santiago grabs for his
to blame outside sources. Who Santiago blames is solely himself. This aspect of Santiago is portrayed many times within this short story. During the very end of Santiago’s struggle with tying the marlin to the skiff and sailing back to the village, sharks begin to feed on the fish. On page 115, ... ... middle of paper ... ... returns to his village with the mere bones of the legendary fish and came to be a hero to his people. This only happened because Santiago pushed forward when everything before
The platypus is among the nature´s most unlikely animals. Its scientific name is Ornithorhynchus anatinus, which in Greek means “duck-like”. The body and the tail of this mammal are covered with waterproof, thick, brown fur which works to trap air and keep itself warm. It has webbed feet and a snout, which are characteristics that can also be found in a duck, thus many people relate them. One of the rare characteristics that this animal has is that its webbing, found in the front feet more significantly

started out going to fish for some dinner, then he caught the biggest marlin ever and it pulled him out in the bay of Cuba even more then he was. After he was pulled out, he hurt his hands and couldn't risk going to sleep because of the risk of sharks. When the sharks finally attacked he lost the marlin which had become a great part of him because he knew that no one would believe him when he told them the size of the marlin. This has to be one of the most memorable fights in a novel that I have ever seen
