Why do sharks attack humans? According to the Shark Research Institute, there are over 400 plus species of shark around the world, which include great white sharks, tiger sharks and bull sharks ...
Additionally, another issue caused by humans which impacts marine life is marine plastic pollution, which poses a threat to marine life. [6] According to the IPCC (2019), since 1950 "many marine species across various groups have undergone shifts in geographical range and seasonal activities in response to ocean warming, sea ice change and ...
The tiger shark is considered to be one of the most dangerous sharks to humans. [1] Although it is found in the Red Sea it is not usually seen near reefs during the daytime. The Grey reef shark is territorial and may be aggressive, and has been involved in non-fatal attacks on divers.

On the evening of 16 March 2009, a new addition was made to the list of sharks known to have attacked human beings.
Sharks could be facing extinction over the next couple of decades. Human interference is largely to blame for the species interference. Overfishing of sharks has increased as the global demand has ...
The most effective triggers of agonistic behaviour in sharks include: [7] [4] [1] hunger; crowding by human divers (independent or group dives) and submersible machinery; sustained targeted pursuit; invasion of the shark's idiosphere, without appropriate warning or consent [8] natural competition for resources with other organisms
Ocean sharks are used to a salt water environment, and the Seine is fresh water, which would dehydrate and eventually kill them, as the Dartmouth Undergraduate Journal of Science points out.
Human exploitation now threatens the survival of this species. With its large size and cutting teeth, the great hammerhead could seriously injure a human, so caution should be exercised around them. This species has a (possibly undeserved) reputation for aggression and being the most dangerous of the hammerhead sharks.
