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 ...
It has been thought that megalodon became extinct around the end of the Pliocene, about 2.6 Mya; [21] [22] claims of Pleistocene megalodon teeth, younger than 2.6 million years old, are considered unreliable. [22] A 2019 assessment moves the extinction date back to earlier in the Pliocene, 3.6 Mya. [23]

[12] Fishermen capture live sharks, fin them, and dump the finless animal back into the water to die from suffocation or predators. [11] [13] Sharks are also killed for their flesh in Europe and elsewhere. [14]
Human exploitation now threatens the survival of this species. Overfishing is the primary driver of shark population declines, which have fallen over 71% since 1970. [98] [99] Extinction is an important research topic in the field of zoology, and biology in general, and has also become an area of concern outside the scientific community.
Humans, 2 million years, even the ancestor of chimps and ourselves only takes it back to 6 million years ago, while sharks go back an incredible 450 million years.
Stories tell of men with shark jaws on their back who could change between shark and human form. A common theme was that a shark-man would warn beach-goers of sharks in the waters. The beach-goers would laugh and ignore the warnings and get eaten by the shark-man who warned them. Hawaiian mythology also includes many shark gods.
For sharks looking up from the waters’ murky depths, it can be hard to tell what humans are. On the backs of surfboards, surfers appear like seals. In confusion and hunger, the sharks may lunge ...
The goblin shark filmed in 2008 was caught at a depth of 150–350m (492–1,148 ft). [30] On 19 April 2014, fishermen in Key West, Florida, while fishing in the Gulf of Mexico, caught a goblin shark in their fishing net, only the second one ever to be caught in the Gulf. [31] The shark was photographed and released back into the water. [31]
