The Great White Sharks: White Death And White Pointer

The bull shark (Carcharhinus leucas) or also named Zambezi shark. The bull shark starts its life when its mother gives birth to about one and thirteen per liter. The mothers give birth around between late spring and early summer. When mating the male nips at the back of the female and grasps one of her pectoral fins in his mouth, this usually leaves a scar for the female called courtship scars. They are immediately on their own and separate from each other. Reproduction with bull sharks doesn’t happen until they are about 10 years old. They are said to be able to live to up to about 25 years. Bull sharks can be found from so many different areas such as worldwide warm waters, shallow waters, and in rivers. They can be in saltwater and in freshwaters.

Usually killer whales prey on about 30 species of fish. On average, a killer whale eats 227 kilograms (500 lb) each day as it needs lots of food to sustain itself. Killer whales hunt in a very strange way called carousel feeding. They force fish into a tight ball by releasing bursts of bubbles .They then slap the ball with their tail flukes, either stunning or killing up to 15 fish at a time. The fish are then eaten very slowly, usually one at time. However Carousel feeding has only been documented in the Norwegian killer whales and some dolphins who live in the ocean.Sharks can also be the part of this whale’s diet. Killer Whales may herd them to the surface and strike them with their tail flukes. Killer whales can induce in sharks and rays

The Great White Shark The Great White Sharks, known mostly because of their white underbellies, are one of the most powerful aquatic animals in the world. They can swim at about 25 Miles Per Hour (40 Kilometers per hour) because of their strong muscles and forceful tails. In addition to that, male Great Whites can grow around 11.5 to 13.1 feet long, while females can grow from 14.8 to 16.4 feet long. This paper will demonstrate how Great White Sharks are an important part of their ecosystem, how their diets work and will adequately describe their habitats. As predators in their ecosystem, Great White sharks help maintain the coral reefs and seagrass habitats.

Shall we? Have you ever wondered about their environment? Or how they survive in the water That they are in. Have you ever thought to your self”wow! Wonder what that Large Mouth Bas s eats?”.

As of now, there is an average of sixteen shark attacks a year. If sharks were truly hunting humans, that number would be much higher than it is. Only about 4 shark attacks are fatal a year, and that number is because one bite from a shark is more than enough to kill somebody. Even a investigatory bite can be enough for a human to suffer massive blood loss, simply because a shark’s mouth size and bite force creates a devastating attack. Sharks are truly not trying to kill humans, and if they were every shark attack would be fatal.

The marine layer is a fossil layer found in the Grand Canyon. The marine layer consists of Stromatolites, which is the oldest fossil at the Grand Canyon. Trilobites are extinct marine anthropoids. Trilobites are found in the Tonto Group, Crinoids, Brachiopods the most common animal in the seas, Bryozoans, Corals, Sponges, and Burrows.

It happened in Big Sur, California when it bit a surfer’s leg but quickly let go; It “probably confused” the surfer for a seal.

Hammerhead sharks rarely attack humans. Only 17 atacked have happened in the last 450 years but none of the attacks were serious enough to be fatal. The animal i'm going to be comparing the hammerhead to is a bottlenose dolphin. The dolphin doesn't chew its food it just goes down the throat like a snakes. I think that the dolphin would be a better survival than the hammerhead because they live in a lot more places than the hammerhead.

Overhunting has had an effect on several different species, the one I will be telling you about is the Harp seal. The harp seal is located in the “west ice” of eastern Greenland, in the “east ice” of eastern Russia, and off the cost of east Canada and are currently being over hunted by humans. Harp seals, and others like the Namibian cape seal, are currently slaughtered more than any other marine mammal in the world. Harp seals are usually 3 weeks to 3 months old when they are clubbed (being hit with a club, like a golf club, until you dead), bludgeoned (being hit in the head with a large, heavy object really hard), or shot to death by a few hundred or a few thousand fishermen, depending on how well they can get to the seal, each year. Harp

Although the orca can be found in both in the open ocean and in the coastal waters, they primarily inhabit the continental shelf’s in the water less than 200 meters deep. In the cold water area is the most distribution limited by the seasonal pack ice. The killer whale is the top carnivore consumer on the food web. Killer whales may be large in size and appetite, but they still act on instinct and have no desire to kill intentionally. The killer whale is also a very playful and intelligent creature like most dolphins are, therefore they do not deserve the name killer whale.

These sharks can be found in cold coastal waters around the world, scientists are not sure how many

The Pan-American Highway Project recently unearthed a bunch of old bones, which were initially found by construction workers. The bones were turned over to scientists, who discovered that the large bones were part of the skeletons of over 40 marine animals. The bones belonged to animals like seals, aquatic sloths, and even an extinct species of sperm whales. These creatures are thought to have been killed off nearly 10,000 years ago.

About 3 or 4 years ago my two cousins and I went deep sea fishing with are dads. We went so far off the coast of Florida you couldn’t see land at all. When we got back ( I was the only one who caught a shark he was a small Hammerhead) from the fishing trip we went back to our condo. Since then I have never caught a shark.

Kayla Norris Biol 105 Dr. Jessy Robbins Critical Thinking: Why the Stellar Sea Lion is Declining The population of the Western stock of Stellar sea lions has been rapidly depleted, according to the Alaskan Fisheries Science Center of the National Marine Mammal Laboratory (Alaska Fisheries Science Center of the National Marine Mammal Laboratory: Marine Mammal Species, 1994). These sea lions have decreased by 85-90% since 1970 (Donnelly, 2003), from over 250,000 to less than 50,000 (Trites & Larkin, 1996) . Although the Eastern Stock is slowly on the rise, up to about 15,000, this is not enough to make a significant impact compared to the devastating loss of the Western stock (Trites & Larkin. 1996).

How differrent about two kind of large tropical shark,the whale shark and the tiger shark? First of all, the whale shark is light blue and has dots on its body whereas the tiger shark is dark blue and has a stripe pattern on its body. The whale shark has legth 10 metres and weight 9 tonnes whereas the tiger shark has length 4 metres and weight 500 kilograms. So,the whale shark is bigger and heavier than the tiger shark.
