Sharks have played a key role in the ocean, and have lived with little problems. Until a hit movie that scared and terrorized people out of their seats called jaws was in theaters. Sharks have been around longer than humans have, and they are on top of their food chain. They have few predators, but there worst predator is man himself. Do these so called killing machines who are looking for revenge trying to eat anyone who steps foot in their home.
The Reflection Paper on the “Sharkwater” The Sharkwater is a documentary created by Rob Stewart in 2006. The movie raises an important question about the survival of sharks, one of the most ancient creatures on the planet. It makes people look on these creatures from different point of view. I cannot say I treated sharks only like monstrous characters from films like Jaws or Sharknado before I saw this documentary.
Theories for its extinction are the decrease of temperature in the water and its prey migrating into colder waters. However, some refuse to accept that the Megalodon shark is extinct. They believe the shark migrated to lower waters and feed upon undiscovered creatures. We will not know until we go down in the deepest depths of the oceans, discover a fresh “megatooth”, or have a
Sharks have been swimming the world’s oceans for more than 400 million years - 100 years before the first dinosaurs appeared (Griffin et al., 2008). Sharks fall under the kingdom Animalia, the phylum Chordate and the class chondrichthyes. There are more than 400 known shark species found in the ocean (Musick and Musick, 2011). In the ocean, sharks help maintain the health of ocean ecosystems and help regulate and maintain the balance of the marine environment (Griffin et al., 2008). These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011).
That’s how you got out.” (98). I on the other hand, have never seen a never-ending pool let alone use one. Also, whilst sitting in the ocean he was bitten twice, one time was caused by a blue shark and the other was due to a much larger shark called a tiger shark “Davey has been bitten by a shark. It shouldn’t have been this surprising; he’d been surrounded by the things” (186).
When the great white shark is a little pup its usually only 5 feet long, when it gets to be and adult it can reach up to 20 feet long. Even an extremely good swimmer can 't out swim the great white shark. The great white shark can smell a tiny drop of blood in 1 billions drops of water. When the great white shark is born it must get away from its mom and dad because if not, the mom and dad might think their pup is something for them to eat. The great white shark is in the waters in, Africa, Australia, China, Japan, and New Zealand.
(Blackfish). Killer whales in the wild are aggressive towards each other just as they are to humans, in 1989 an accident involving two whales: Kandu and Corky resulted in Kandu bleeding to death. (Kirby 2) this would have never happened if the whales had the enough space they needed to separate from each other. Contrastingly, killer whales in the wild are more peaceful toward each other and humans. There is only one accident of an orca biting someone in the wild.
However, when the whales are put into tanks they experience many more dangerous medical conditions. “Killer whales are known for their impressive dorsal fin, which in males can reach 1-1.8m tall. But, in captivity, they collapse”(Warley). In Seaworld most of the whales have collapsed fins that are turned over and are no longer straight. In the wild only one percent of dorsal fin collapse happens among whales.
marine animal I’m researching is The Great White Shark. They are also known as, White Death and White Pointer. Great White Sharks are located off the coast of California, Australia, South Africa and the northern United States. Other continents and countries call them Tommy Sharks, Blue Pointer, Uptail, Maneater, etc. Great White Sharks are mostly infested in the USA and Australia and have caused 188 deaths in total.
Sharks are extraordinary creatures they are also the fiercest predators of the sea, but they weren’t always that way. Sharks have evolved in many ways to become the animal that is know today. Sharks have grown jaws and teeth like scales. Sharks used to be very small and not intimidating at all. Sharks about 370 million years ago were “four feet long and their mouth’s were on the bottom of their heads.
Dylon. G Mrs.Hornseth Period:4 Bottlenose Dolphins The history and traits and what a dolphin looks like is what this rough draft is going to be mainly about. Dolphins have a big reputation for having lots of curiosity. Some people thought that dolphins were smarter than humans considering that they have more lumps and a bigger brain.
Hammerhead sharks are carnivore because they eat meat much as fish species. They will eat fish to regain their energy because they use most of it swimming. They also use energy by using their sense of smell that allows them to detect blood. When a shark reaches a point when they can’t use any more energy, they will go deep into the ocean and stay there. Their preys won’t spot them as easily when they are deep in the ocean.
How much do you really know about the hammerhead shark? Most people assume a shark is a shark, but there are many different types of sharks all with their own distinct qualities. However, the nine species of hammerhead sharks are easily identified by the unique shape of their head which resembles a hammer and is the origin of their name. Hammerheads are cold-blooded mammals that can grow up to 25 feet in length and weight as much as 1000 lbs.
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.
