Why Do Bull Sharks Migrate

Sharks do not have skeletons, but just cartilage. Also their jaws can move independently without any of their other body parts. It allows them to have a stronger hold on their prey. Sharks have oil in their liver that allow them to eat less often. So when they eat us up, they must be really hungry. Their fins help them feel vibrations of other creatures so that they can get into position to pounce on their prey.

Sharks are aquatic creatures and very important to the living with lots of information humans may not understand. To start off, femeles give birth to 7-9 sharks per litter that are 3-4 feet at birth. Next humans believe all sharks are monsters but out of 400 species only 4 sharks have been claimed to attack on humans. Lastly sharks attack for 2 main reasons one reason is for defense and predation. They attack in defense when humans are in or around their territory they attack in predation mistaking people for seals. In conclusion sharks are creatures that humans are still learning about and try to understand them better.

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.

Sharks grow slowly and reproduce at a low rate. Their natural rate of replenishment is low, because they reproduce late in life and produce few offspring (Sims and Reid, 2002). If too many of a certain shark species is killed in a certain area, it is possible that that species may never recover. For example, the number of dusky sharks and sandbar sharks off the eastern United States decreased by more than 80% between 1985 and 1995. The sand tiger shark and the great white shark are threatened world-wide. Despite reproduction, little is known about the status, behavior patterns, and their migration patterns of most

Most sharks eat their prey whole, or tear off large chunks of flesh at a time.

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.

Killer whales are one of the most fascinating displays of ocean life. The killer whale has characteristics that are important to its survival in the ocean. It is interesting to know that killer whales have a plentiful diet. It is astounding to see how killer whales behave in the ocean. I plan to tell you about the killer whale, its characteristics, its diet, and its behavior in the ocean as well as the predation of the orca.

They are usually found in the Northern Pacific Ocean, ranging as far south as the Sea of Japan and as far north as the Bering straight. It’s believed these sharks spend a majority of their time in epipelagic waters, but individuals have been observed in waters as deep as 660 meters. Salmon sharks are generally about 200-260 centimeters long and weigh around 220 kilograms. They are usually medium grey to black in color with a white underbelly and short, cone-shaped snouts. Overall they have a great resemblance to Great White sharks, hence the nickname “Mini Great Whites”. The primary prey for these sharks is salmon, but they also eat squid, herring, and pollock. Salmon shark are also ovoviviparous, with a litter size of 4-5

Is shark culling okay given the number of shark attacks that have occurred? Recently it seems that the number of shark attacks has increased with seven fatal attacks in the past 3 years in Western Australia (WA). These recent attacks have led the WA Government being granted an exemption to start culling sharks with a catch-and-kill shark program. A lot of people including scientists and surfers are against this controversial decision. For people to make an informed decision they need to have an understanding of where the shark fits into the marine ecosystem, as well as the reasons presented for the use of shark culling and the arguments given that oppose such extreme measures.

Also hey are very unique and interesting. They can get up to 15ft long. Next blue sharks like to move around so they don’t stay in one spot for long. At last watching the movie jaws made people have many opinions that are oncel sharks. People find sharks very threatening but they are just like us.

In conclusion, Mako sharks unique characteristics are what distinguishes them from other species of sharks in the waters. While their population has declined due to hunting for their meat, hide, fins, or because they have been viewed as being aggressive towards people, the Mako shark still remains to be an incredibly unique marine creature (“Mako Shark”

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 can gather and keep the air into their stomach to keep them from floating.

Sharks have a long history, they can be dated back to over 400 million years ago, one of very few species that live for such a long period without distinction. Within over 400 different species, the smallest shark is only 17 cm in length which is the dwarf shark; while the largest

Their bodies are also shaped somewhat like a torpedo to give them a more streamlined affect in the in water. Yet, some types of sharks, the ocean dwellers have a flat body similar to that of skates and rays. Sharks can travel with great bursts of speed especially when attacking their prey or when excited.
