Essay on All About Shark Cartilage

Sharks have been in our oceans for almost 450 million years. Those millions of years of evolution have allowed many different shark species to develop abilities, and to become perfect predators.

They do this because of the limited amount of space on the ship. Shark liver oil is used as a source of vitamin A, and some people believe that the cartilage and liver of a shark are extremely beneficial to human health. In earlier days the sharks' teeth-like scales on their skin was used as fine sandpaper, and when the scales were removed from their skin it made fine leather. This leather was used for making shoes, belts and handbags. Each year thousands of sharks are killed unintentionally due to nets used to catch different types of fish, and sometimes humans kill sharks because they fear them (Springer and Gold, 1989). All of these activities have resulted in many shark species being in danger of extinction.

Arising over 350 million years ago, the shark species has been labeled as a human devourer. Now, with the increase in human population, the demand for shark meat, fins, and cartilage are at an all time high; therefore, the existence of the shark is becoming a concern (Budker 1971). Individuals are conditioned to think of sharks as a negative aspect to the environment, which is prolonging the effort to save shark species from becoming extinct. With that in mind, some private as well as national organizations have accepted the challenge of educating and informing people about the existence of the shark specie and its importance to the sea.

The things that sharks are being killed for is sickening. So far, humans have decimated about 90 percent of the world’s shark populations for the sake of shark tooth jewelry and jaws that tourists buy in massive quantities, sharkskin accessories, phony medicines made from their cartilage, and a huge range of cosmetics, deodorants, moisturizers, sun tan lotions, and lip balms that use shark liver oil as a base because it makes our skin soft. (Check the ingredients of these items before you buy. If they contain “squalene” or “squalane,” leave them on the shelf.) (M. R., Ph. (2015, February 08). The Most Misunderstood Shark Fact Of All Time. From

This organism causes the sharks to go blind. Luckily Greenland sharks are mainly scaevngers and heavily rely on their heighted sense of smell.

Sharks have been around longer than any human. They are descendants of the dinosaurs that have survived what so many could not. If this versatile animal does not make it to the years ahead, then the earth is in for dire times. Sharks are an indicator about the state of well being of the ocean. If sharks are spotted in a particular area of the ocean we then know that this area of the ocean is healthy. Whereas areas where there are no sharks, the water usually unsuitable for most aquatic creatures.

Throughout the early Paleozoic and Mesozoic ages, the major sharks belonged to a set called Hybodontoidea. They had fins and bony structure

Shark finning is popular in asia. They cut the fin off of the shark, and then throw the shark back in the water. Since sharks are being killed for just the fin, there are bans against finning. People also started just killing them after the movie Jaws came out(8). It pictured a Great White shark attacking people viciously. It upset people because it was based on a true story, but in the actual occurrence it was a bull shark that attacked the people not the Great White(8). There are many shark sanctuaries set up in the ocean to protect them. They can go there and live without having to worry if they will get caught in a net or get their fins cut off. In many countries there are bans on Great White Shark products. There are many projects in effect for protecting Great White Sharks(Institution, Smithsonian). Great white sharks are illegal to hunt because they are endangered. They also have a short life span of about sixty years, but very few make it to even thirty. There are many signs that say the great white population is increasing slowly but steadily(Institution,

This article talks about what sharks does in order to survive and what are they capable of doing. According to the article, sharks do not sleep; but rather, they have rest periods throughout their day. Sharks are capable of hearing anything below 1000 Hertz and can also swim up to 20 mph. Sharks skeleton is made up of cartilage rather than bone. According to the article, cartilages are lighter than bones. What keep them from floating are their large livers. Sharks can gather and keep the air into their stomach to keep them from floating.

To understand why we need sharks, we have to first look at what an ecosystem is. An ecosystem, as described by the Mirriam Webster Dictionary, is “a system, or a group of interconnected elements, formed by the interaction of a community of organisms with

It’s important to realize what sharks are capable of. For example, it states in “What do you know about Sharks?” by Sharon Guynup that “[the dusky shark] exerts 18 tons of pressure per square inch on a victim.” That only being one of hundreds of species one

Within 1996-2000, shark fin imports increased by 6%. To get the shark fins, men would catch sharks, cut off their fins, and then throw them back into the water. Are shark fin soup worth killing millions and millions of sharks? There are also many different uses for the different parts of the shark. For example, shark oil can be used for makeup and cosmetics, shark cartilage pills supposedly benefits our health and is old in health food stores, and shark steaks are sold all over the world. Although there are many economic benefits from shark finning, it can also threaten recreational fisheries, and other traditional ways of fishing.

Most people are terrified of sharks and want nothing to do with them others love them I’m one of the ones that love them I think they are just misunderstood intelligent creatures and this will help you realize that too. Sharks have been on earth for at least 420 million years ago that’s 200 million years before the first dinosaur! Sharks outlive humans they have been on earth longer and have longer life spans the oldest living shark is 500 years old while the average human can live as long as 70 years in perfect health. Sharks like people come in all shapes and sizes and swim everywhere from the arctic circle to the Caribbean. Some sharks are big some little some long and thin some wide and short they come in every size imaginable and in the weirdest conditions like seas and oceans with other animals ready to eat any injured sharks to lakes hunting fish they live almost everywhere.

Recent studies from the article “Hammerhead shark migration gives new hope for conservation” discusses how these hammerhead sharks have been listed onto the IUCN (International Union for the Conservation of Nature) since 2007, also having certain regulation about international trade threatening species going extinct. Dr. Tristian Guthridge explains the benefits of understanding the shark’s behavior and more research of where these sharks are migrating, and possibly manage the time of fishing in the areas to eliminate human and shark altercations. With the wide spread of ocean water it can be difficult to study the traveling of sharks; however, the research group was able to tag the sharks “with both acoustic and satellite tag, and use photo identification and laser photogrammetry” (Charlie Huveneers).

Sharks have a very different breathing system than most animals that live in or on this earth. Sharks also receive oxygen from the water through gills, yet, unlike fish, sharks do
