Great Hammerhead Shark Migration Essay

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

head of a hammer. Their eyes and nostrils are at the ends of the hammer.

There would be too much damage to the nervous and muscle system to regain use of the arm fully; the muscle and nervous system would not be able to send messages to the brain in order to control the arm.

Sharks are one of the oceans top predators. They vary in size from the extremely small dwarf shark, to the colossal whale shark. Sharks can be found all across the world’s oceans, from the tropic waters of Hawaii to the sub zero temperatures in the Artic oceans. Of the hundreds of sharks a select few species have actually been recorded in the Artic. Of these few, only three of them spend the majority of their time in these harsh, freezing waters. These sharks are the Greenland, Pacific Sleeper, and Salmon sharks.

The cause of this debate comes with the return of White Sharks to the area. Over the past few years, there has been an increase of this apex predator to our coasts like never before seen, most notably since Labor Day weekend in 2009. Five sharks had been tagged by a marine biologist, Greg Skomal, and have been closely tracked and documented since. Skomal is a key player in this research as project leader

Great hammerhead sharks appear to adapt well to their environments. One of their capabilities is that they are opportunistic predators and are willing to eat anything they can get their hands on to help them survive. Consequently, one concern would be the changes in temperature in the water. The hammerhead does not seem to adapt well to the cooler waters.

Sea Shepherd Conservation Society’s article “The Brutal Business of Shark Finning” reminds us that sharks play a key role in the ocean as both predators and scavengers.

Beginning with the simplest one-celled organism, an extraordinary animal rose in the murky waters entitled to a non-comparable killing-eating machine. This organism has become nature’s most genuine and most successful creature that it has remained unchanged for over 250 million years. Nature finally invented the perfect king of the sea. This animal has given the sea it’s “living” adjective; in turn, it was entitled—the “great white shark.”

Hammerheads are usually talked about as if it was just one creature but in a matter of fact the hammerhead shark comes in nine different species. The largest of the species is the Great hammerhead shark, they can range from 3.4m to 6m long and 225kg to 450kg in weight, the females are larger than the males but males mature at an earlier stage, although smaller sizes are more commonly found. The hammerhead sharks habitat is offshore in water depths of 300m, also in shallow coastal areas like continental shelves and lagoons. The hammerhead moves poleward when migrating to get to cooler waters when it is the summer season, which is caused by the abiotic factors. The young swim mostly in shallow waters along the shores almost all over the world

The increase in shark attacks in the Carolinas this summer is allegedly due to warmer waters and droughts, according to George Burgess, the director of the Florida Program for Shark Research. Warm waters and the high number of people visiting the beaches this summer is a recipe for more attacks, according to

The bull shark will migrate to follow its food but if there is enough in one place it will stay there. Because most sharks don’t call any specific part of the water home it is an unusual behaviour bull sharks have. The Bull shark is well known for its very aggressive behaviour. It is known to attack people because of its extremely territorial nature.

Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man. Sharks are classified in the order

Whales move a far distance, and the gray whales are the farthest mover. Some whales move between onshore and offshore areas, and the others migrate Iatitudinally (north-south). For instance, the Brazil and New Caledonia whales migrate from low-latitude grounds to high-latitude grounds. In general, whales migrate to cold grounds in summer to feed and move to hot grounds in winter to breed. Whales move straightly. There isn't any evidence which can prove they navigate by the magnetic field
