Basking shark Essays

A shark tooth is one of numerous teeth in the shark’s mouth. Different sharks can be classified on the basis of the teeth they have and the functions that such teeth perform in consuming their prey. There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangle upper, and non-functional. Sharks have a complete set of teeth when they are born. These teeth are modified placoid scales with an outer layer of enamel, dentine and a central pulp cavity; similar to

to attract prey in the dark. They are a bioluminescent creature which mean that they have lights on their body that they can activate. They have lights on the bottom of their body that they use as a defense mechanism to get away from predators like sharks, dolphins and the dragon fish and those are their main predators and when they see the light under the Viperfish they believe it's the faint light from the top side so they just ignore them. When it's daylight they hunt at depths of 1500 meters or

When seeking to find a ted talk that interested me, David Grubers speech,“Glow-in-the-dark sharks and other stunning sea creatures” caught my eye. David Gruber, a marine biologist, presents his research and discovery addressing the bio fluorescent proteins in marine life. After exploring the world and the depths of the ocean, he creates the theory that a multitude of sea creatures pertain this bio fluorescent protein allowing them to glow. He later concludes that these light-up creatures is “one

Behavior Some sharks migrate over great distances to feed and breed. This can take them over entire ocean basins. While some shark species are solitary, others display social behavior at various levels. Hammerhead sharks, for instance, school during mating season around seamounts and islands. Some shark species, like the great white shark, attack and surprise their prey, usually seals and sea lions, from below. Species that dwell on the ocean floor have developed the ability to bottom-feed. Others

The whale shark (Rhincodon typus) is the largest fish in the world. The head is flattened and the wide mouth stretches almost as wide as the body. The dorsal fin is particularly large and the tail has a half-moon shape. The coloring of this whale is very distinctive. It has dark greyish-blue colour on the back and sides, and also pale yellow blotches. The underside of the whale is pale. Ridges run along the whole body all the way to its tale. It has 5 massive gill slits that are on either side of

The Fish, by Elizabeth Bishop is a free verse structured poem that navigates readers through the writer’s vivid perception of a fish that she has just caught. The fish depicted in this writing was allegorical to one’s survival of life’s tumultuous nature that can leave one scarred and battered with harshfully visible remnants. The writer skillfully employs literary devices that create an overwhelming image in the reader’s mind of the true meaning behind the appearance of the fish. Bishop expresses

the shark population Summary There is a rapid increase of rays, skates and numerous small pieces as a result of the decrease of sharks along the eastern seaboard. As a result of intense fishing of sharks in the northwest Atlantic over the past few decades, the shellfish populations such as scallops and Chesapeake bay oysters are decreasing. One of the contributions to the 73 million sharks killed each year is due to the supply of fins need to make the Chinese delicacy shark fin

relationship between shark feeding behavior and shark humans attacks, and what are the effect of overexploitation in shark populations? Hypotheses: If sharks have low visibility, they can confound for a fish a man’s foot or calf. If fishing behavior increase, it will be a decline in shark population. There is a significant difference between cruising swimming and filter feeding speeds of basking sharks. Experimental design: • Cruising swimming speeds and filter-feeding of basking sharks. In 100-km

Humans are afraid of sharks for various reasons. Some of those reasons are the shark’s size. Humans tend to be afraid of bigger animals, especially when they are known to have killed humans in the past, which is another reason humans are afraid of sharks. One other reason humans are afraid of sharks is because sharks have been misunderstood and they have been portrayed as something they’re not. There are over four hundred species of sharks in the ocean and sharks are considered the most dangerous

Sharks are extraordinary creatures they are also the fiercest predators of the sea, but they weren’t always that way. Sharks have evolved in many ways to become the animal that is know today.Sharks have grown jaws and teeth like scales. Sharks used to be very small and not intimidating at all. Sharks about 370 million years ago were “four feet long and their mouth’s were on the bottom of their heads. The Cladoselache also had long spines along its back” (Shark Savers “450 Million Years of Sharks”)

learn and know about sharks. One thing is that sharks sometimes hunt alone or in packs. They just don’t attack their prey and eat it, they stalk the prey first and then wait for the right moment. People have been killed by sharks but it’s because they were probably mistaken for a seal. Another thing is when sharks hunt or attack they have a very powerful bite.

In the musical West Side Story, the portrayal of the “Jets” and the “Sharks” highlight the issues of race and ethnicity that impact the formation of identity. In an article, “On Broadway”, Sylviane Gold argues that “musicals have reflected and perpetuated the racial rifts and injustices of American society” (81). West Side Story brings across the racial and ethnic divide of an America dealing with issues of identity and an influx of immigrants both in terms of its presentation of the character as

For years people have thought of sharks as man eating beasts, but what is really behind those sharp deadly teeth? What is the science behind the shark? Could it be that sharks only kill to survive the deadly ocean waters? Much of our fears come from fake things, but there is certainly no reason to be terrified by a shark. People swim with sharks every day without a cage or any other protections because they trust and don’t fear them. Behind those teeth they really don’t want to hurt you. They have

THE EVOLUTION OF THE CARCHARODON CARCHARIAS (SHARK) for my research task, I chose to study and track the evolution of the shark. These beasts being one of nature’s top predators in the world and dominating the oceans surrounding our continents. I chose these fierce creatures as they were a perfect example for me to use in explaining the evolution and the branching of evolution purely based on the fact that they have been around for millions of years through prehistoric times changing and evolving

and that was the moment he became hooked. Later in his life he became an American documentary filmmaker specialising in underwater cinematography. Mike DeGruy was a regular on Shark Week and even a shark attack survivor. He is well known for his shark attack in april of 1978 where he got severely bitten by a grey reef shark. He was a member of many deep sea expeditions and was a part of the team that first filmed the vampire squid and the nautilus. Mike DeGruy died in a helicopter crash in Australia

Doctors, astronauts, farmers, students, teachers, athletes, police officers, and people from all walks of life, come together, to compete against each other, on the Game Show Survivor. They live off of bugs, coconuts, and anything else they can scavenge with a machete and axe, and sometimes, they are lucky enough to win a fishing spear and gain the ability to catch fish. Each person comes in knowing who they are, their morals, values and limits, but they can easily come out a ‘rat’, ‘cancer’, ‘snake’

History of commercial fishing in Hawaii Shortly after Statehood, a U.S. De­partment of Interior, Bureau of Com­mercial Fisheries proposal labeled the Hawaii fishery as "dying". Hawaii's major commercial fisheries had been dominated by traditional prac­tices that reflected Hawaii's Japanese immigrant heritage and its impact on the local fishery and seafood markets. The predominant commercial fishery was aku (skipjack tuna), which was caught by a live-bait, pole-and-line, wooden sampan fleet, known

is about the shark finning epidemic. Stewart who from his childhood loves the ocean and hates the fear of sharks is now under water photographer and biologist. He goes under the sea and wants to find the truth of shark fish. He wants to convey the message that sharks are not our enemies and are greatest hopes. As we know two-third of earth surface is covered by water. Sharks had come to the earth before 400 million years ago before the dinosaurs which came 150 million years ago. Sharks are believed
