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]
[10] [11] Sharks are often killed for shark fin soup, which some Asian countries regard as a status symbol. [12] Fishermen capture live sharks, fin them, and dump the finless animal back into the water to die from suffocation or predators.

With an estimated 12% of bird species, 26% of mammals, 31% of sharks and rays, 36% of reef-building corals and 41% of amphibians at risk, we need to consider every tool we have to secure the ...
Fishermen capture live sharks, fin them, and dump the finless animal back into the water. Shark finning involves removing the fin with a hot metal blade. [129] The resulting immobile shark soon dies from suffocation or predators. [135] Shark fin has become a major trade within black markets all over the world. Fins sell for about $300/lb in ...
Animals like the woolly mammoth and Tasmanian tiger may be revived thanks to advances in gene editing technology, but critics say this burgeoning science is a distraction from the real work of ...
Otodus megalodon teeth are the largest of any shark, extinct or living, and are among the most sought after types of shark teeth in the world. This shark lived during the late Oligocene epoch and Neogene period, about 28 to 1.5 million years ago, and ranged to a maximum length of 60 ft. [ 13 ] The smallest teeth are only 1.2 cm (0.5 in) in ...
