Tiger Sharks Research Paper

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

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.

Many people call sharks beasts, terrible things, killers, but they are not. For instance sharks need to eat to just like humans. Sharks can eat all day. When sharks eat too much they throw it up and eat more. Sharks fend for themselves when they are hungry they might find other sharks and eat them. Sharks eat squid, shrimp, sardines, tuna. Besides sharks can never stop moving so they don't’ stay in one spot. Lastly sharks might look mean but they are

The Australian Grey Nurse Shark is also known as the Spotted Ragged-Tooth Shark and as the Sand Tiger Shark ("Australian Threatened Species”). The species is identified by its gray to gray-brown coloration, the possible presence of reddish/brownish spots on the caudal fin and posterior half, their countershading, and by its two almost equally sized dorsal fins. They are known to grow over 3.6 meters in length with the males and females maturing at different lengths, 2.21 meters and 2.2 meters, respectively (McGrouther, 2015). Females also mature significantly later at 9-10 years than their male counterparts, who mature at 6-7 years. Their diet consists of fish,

For 350 million years, sharks have swum the earth and sought out their prey. Before the dinosaurs every set foot on earthen shores, sharks lurked in the murky depths of the ocean. On the North Shore Shark Adventures tour, you will be introduced to the Sandbar and Galapagos sharks. If you are really lucky, a Tiger shark may make an appearance.

the black tip shark has a very pointy nose in fact more pointy than any other sharks it uses a chemical odor to attract a mate near by.

There are many ways that sharks have interdependence. Only a few sharks have developed camouflage to capture their prey They are on the top of the food chain in the sea because most of them are carnivorous. Found in all seas but usually not as deep. Sharks are found in depths of 2,000 meters and 7,000 feet or even deeper. The deepest depth that humans have recorded is 3,700 meters and 12,100 feet. They

The White Shark, also known as the Great White Shark, is one of the most furious predators in the oceans worldwide. Same as every species, the White Shark is classified into major groups. This is called taxonomy. The taxonomy for this species is

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

The Great White Shark, scientifically known as the Carcharodon carcharias, was possibly 2016’s scasriest fish. The Great White shark’s environment was the aquatic marine biome, and it usually lived off the coasts of Australia, South Africa, and California. Although thier usual habitat was shallow coastal waters, Great Whites have been recorded in depths up to 3,900ft. The climate of the water they lived in was between 54 and 75°F. The limiting factors of the shark’s habitat were the nutrients and oxygen levels in the water. The Great White shark was the largest predatorial fish in the whole world.The Great White shark shared the ocean with about 440 other species of sharks, but its only natural predator was the Killer Whale, or

The great white shark also known by its scientific name, “Carcharadon Carcharias” is one of the most feared and dangerous creatures in the world. Great white sharks descended from their ancestor who was the Megalodon and it was the largest shark/fish that lived during the prehistoric times. It had a similar appearance to the great white shark and was three times the size of it. Great white sharks are blue/grey on top and are white below, there are also one of the biggest shark species measuring at up to 5-9 metres in length and can weigh up to 5000 pounds. Great white sharks are known to humans for fatal shark attacks and their ferocious behaviour and appearance. These sharks also have large teeth measuring up to 7.5cm all positioned in rows

As the blood reaches the gills they are then split up so they have more it is oxygenated by the water ,when water passes over the gills, a system of fine blood vessels takes up oxygen from the water. The great white shark lives in fairly temperate waters and mostly in tropical waters because such temperatures might cause the shark to overheat. The great white sharks home is all over the place but they are mainly located around Australia and New Zealand. Most sharks are found in the area up to 2000 metres below sea level, certain species prefer specific levels, mainly due to the prey available and the temperatures experienced at those depths. But the great white shark preferably likes the open ocean and also the basking shark these types of sharks are called pelagic

The Great White lives in warm water along the coasts of land masses. You can find the sharks swimming on the coasts of California up to Alaska, all over the eastern coast of the states, the Gulf, Hawaii, most of South America, South Africa, the entire perimeter of Australia besides the north coast, New Zealand, and in the Mediterranean Sea. Although you can find the sharks in all these areas, they are mostly concentrated in the United States, Japan, and the Mediterranean Sea. The sharks don’t swim

Whale Shark (Rhincodon typus) has the toughest and thickest skin of all the animals in the world. It reaches up to 14 cm of thick; whale shark is pale on the underside and dark gray-brown color with white spots on the top. This can serve as a camouflage looking up or down the sea for shark’s preys (SRI, 2008). As all the other Chondrichtyes, Whale Shark skin is covered with little cartilaginous tooth-like structures, this are dermal placoid scales arranged
