The Great Hammerhead Shark Sharks are one of the most feared sea animals. They live in oceans across the world but are most common in tropical waters. There are over three hundred fifty species of sharks. They can be broadly categorized into the following four groups: Squalomorphii, Squatinomorphii, Batoidea, and Galeomorphii. The shark family Sphyrnidae that includes the Hammerheads are a part of the Galeomorphic classification.
Megalodon had the most powerful bite force of any creature that has ever lived! In 2008, The US and Australian palaeontologists both used the latest technology to see how powerful the bite of this magnificent shark was. A modern Great White Shark has about 1.8 tons of bite force. This led them to finding out that the Megalodon had a bite between 10.8 and 18.2 tons! This would mean they could easily crush a prehistoric whale’s skull as easily as we would eat through a banana!
The great white shark (Carcharodon carcharias), also known as the great white, white pointer, white shark, or white death, is a species of large lamniform shark which can be found in the coastal surface waters of all the major oceans. The great white shark is mainly known for its size, with mature individuals growing up to 6.4 m (21 ft) in length (although reports have been published of great white sharks measuring over 8 m (26 ft), and 3,324 kg (7,328 lb) in weight).   This shark reaches its maturity around 15 years of age and was previously believed to have a life span of over 30 years. The true lifespan of Great white sharks is far longer; now estimated to be as long as 70 years or more, making it one of the longest lived cartilaginous fish currently known.  Great white sharks can accelerate to speeds that exceed 56 km/h (35 mph).
They also prey on many delicate aquatic creatures as the innocent sea urchin, unarmed crab, unprotected squid, indefensible octopus, and fish. These vile creatures prefer different animals to eat and it varies from otter to otter. The hooligans eat about 25% to 30% of their weight. A large male may consume as much as 25 pounds of food daily. Meaning these thugs murder creature after creature feeding their insatiable appetite.
Apart from a small twist in this book (a hungry fifty foot shark) it is safe to declare that Steve Alten's "Meg" is just the same as any other science fiction paperback. In order to save the world, Professor Jonas Taylor, our brave scientist, confronts the Megalodon in a one-man sub. He is quickly swallowed whole along with a couple whales here and there. Once inside Meg's stomach, the professor grabs a five foot long tooth that just happened to be floating around in the shark's belly and pierces through the stomach where it is tangible to the heart. Needless to say, the shark simply refuses to live with a big hole in its heart and dies, pouring gallons of blood into the ocean in the process.
These lion ﬁsh prey on all different types of animals, such as: crabs, shrimp and smaller ﬁsh; and have very little amount predators giving them the place in the higher levels of the food chain. Since it is so high in the food chain and preys on almost anything, it has managed to survive in the Atlantic Ocean perfectly. In the Atlantic, lion ﬁsh are deﬁned as invasive species, which means, "a non-native organism that has intruded into an area and may have serious detrimental effects on native organisms, the local economy, and human health". sadly many accidents have led to the invasion where the lion ﬁsh has spread all across the Caribbean Sea and up North in places like Rhode Island. It is hypothesized that the origin of the whole problem came from only six lion ﬁsh that were accidentally released from an aquarium to the Atlantic Ocean in 1992 during hurricane Andrew.
They are eaten by Sperm Whales, Southern Elephant Seals and Colossal Squid. Globally, almost 80% of the toothfish species sold on the world market is illegal. Australian fisheries are some of the largest legal fisheries around the world. Macquarie Island Toothfish Fishery: located off of Tasmania, began in 1994 when the fishery was granted with its permit. It is an aquaculture fishery harvesting for commercial fishing.
Also, the shark's blood is cold - cold blood usually means evil, lonely, unhappy. Warm blood means happiness. The shark is a cold-blooded killer. Another poetic device used was simile as in 'his fin, like a piece of sheet iron'. This tells the reader that his fin can cut through anything that crosses his path.
SO what the killer whale does it dives in the water and become submerged in the water for more than 15 minutes so they can use echolocation and listen where their prey is 3. Another selective pressure is the pressure that increases as they dive. Unlike human scuba divers, a whale doesn’t breathe air under pressure. It inhales only at the surface. Furthermore, in diving mammals, the alveoli collapse at about 3 atmospheres of pressure (about 90 feet), forcing air into the bronchioles (rigid air passages), a region where gases are not exchanged.
Although sharks did not appear on earth until about one hundred million years ago and were thought to be of decent of the mackerel shark modern day Great White Sharks teeth have been dated back sixty five million years ago to times when dinosaurs were still alive. Early in shark evolution two main families were created. One of the lineages in which most modern day sharks are decent of were equipped with coarsely serrated teeth. The other lineage were equipped with finely serrated teeth but could reach over 50 feet long and have been discovered to eaten large marine creatures such as whales. There are over four three hundred and seventy species of sharks ranging in size from the smallest shark the pygmy shark which doesn’t normally grow larger than six inches , to the whale shark which can attain sizes of thirty five to forty feet.
