The Northern Snakehead can survive up to four days out of water and can grow up to 33 inches long. The species has been nicknamed “Frankenfish” due to its shark-like teeth and aggressiveness. It was first introduced in a pond in Crofton, Maryland in June 2002. Researchers believe the species ended up in the U.S. due to uncaring disposal of aquarium pets. Other researchers think some people were trying to breed Snakeheads as they bring a large amount of money in some areas.
It is the deadliest shark known to man and has been accounted for the most caused deaths. Hammerhead- this shark is easily recognized because of its hammer shape like head. The hammerhead shark has this type of head because they have all of their sensory organs in their head. Reef sharks- this sharks is referred to as the black tip shark because of its black fins. They normally live in the reef eating on small pray such as fish, lobsters, and small mammals.
Jaws Essay Jaws, directed in 1975 by Steven Spielberg was a great film that made audiences barely hanging on the edge of their seats.

Within this movie, there are many interesting camera shots that create tension and suspense. These shots help set a mood towards the audience.
Litter sizes vary from one to 15 with White Tips are a commercially important animal to humans seeing as how its fins are used for shark fin soup and its meat and oils utilized for consumption, its hides are often used for leather as well. Many scientists have referred to this shark as the most dangerous shark in the world, despite the more notorious Great White and Tiger, the white tip is responsible for more human deaths then all shark species combined. With one incident alone, the torpedoing of USS Indianapolis on 30 July 1945, giving a minimum figure of between 60 and 80 sailors killed by sharks. While diving with these sharks is done often it is not advised. So Respect and Fear this great animal who is number 4 on animal planets deadliest
Most jelly fish are dangerous as they sting other creatures, when touched by one of their tentacles. Clown fish are immune to stings thus why Marlin wasn’t affected. 14. Compare Dory, Bruce and Nemo, which is the best adapted for speed and why? Bruce is best adapted for speed, as he is a shark and needs to be fast to catch and hunt down his prey.
The resulting anxiety and tension cause fights between orcas. In the wild, orcas have strong social bonds that may last for life, their social rules prohibit serious violence against each other, and when fights do occur, they can find space to flee. In captivity, there's nowhere for them to go, which leads to injuries and death.” (SeaWorld of Hurt) Besides fighting with fellow killer whales, Orcas are biting the bars, concrete and tanks to escape due to stress and anxiety. The diet of a whale in captivity is unlike the diet of a whale in the wild. PETA’s campaign SeaWorld of Hurt shares, “In captivity, orcas are unable to hunt and obtain water from their prey, so SeaWorld gives them gelatin, a substance that is not natural for them, in an attempt to keep them hydrated.
Dr Carl Meyer from Hawaii Institute of Marine Biology stated that mass levels of shark culling “runs the risk of ecosystem-level cascade effects where a general lack of sharks results in boom or bust in populations of species further down the food chain”. Furthermore when nets are used to trap sharks, often animals such as dolphins, turtles, whales and dugongs become trapped in them. Turtles are one of the most endangered species as a whole and are just innocent bystanders in this war between humans and sharks. We need to be careful of not affecting other animals in this quest to reduce shark numbers in the name of nothing. Sharks can already be caught legally by commercial and recreational fishers so any cull would be largely
Some manta rays live in a particular location while others travel from places to places. Manta rays are filter feeders. They consume a large quantity of zooplankton by filter seawater through their mouths while swimming. And usually many manta rays swim in lines with their mouths open to filter more zooplankton. Manta rays are huge in size so only sharks and killer whales can harm them and eat them.
The Consequences of Overfishing Overfishing has been identified across the world as a prominent environmental issue. Fish and other marine animals, such as sharks, sea turtles and dolphin, are retrieved from the oceans through indiscriminate fishing practices at a rate that cannot be sustained by natural reproduction (Jackson, 2001). Systematic overfishing with bottom trawling, dredges, and drift nets depletes the ocean of innumerable species at an alarming rate and alters the ecological balance in marine environments. The actions of shortsighted commercial fishermen have brought tremendous adverse environmental and economic consequences upon the entire world. The continuation of unrestricted fishing will worsen world hunger among impoverished coastal communities, many of whom depend on the abundance of fish to feed themselves and their families, and result in ultimate environmental chaos and the extinction of thousands of In recent years, the demand for fish, a healthy food rich in omega-3 fatty acids and lean protein, has sky-rocketed.
Humans have been known for destroying coral reefs through unlawful fishing habits. Cyanide fishing has been classified as a destructive fishing practice, yet is still being used in our oceans today. The destruction of coral reefs is greatly due to the fact that many people are unaware of a number of things. Such as the what coral reefs are, the key role they play, what cyanide fishing really is as well as the negative effects the fishing will cause. Occupying less than one percent of the ocean floor, coral reefs are home to over 25% of all marine life.
