The scalloped hammerhead is critically endangered. Scientists say sharks and rays are disappearing from the world's oceans at an "alarming" rate. The number of sharks found in the open oceans has...
Since 1970, the population of oceanic sharks has dropped by 71%, and many species are facing extinction. If you're not a big fan of sharks, this might seem like a good thing, but the absence of sharks would be devastating to ocean life.
Scientists worry the sharks’ dwindling numbers could bring ecological collapse as they play a number of key roles in the ocean. Unlike many fish, sharks take a long time to reproduce.
More than one-third of the world's shark and ray species are now facing the threat of extinction, the International Union for the Conservation of Nature (IUCN) has declared in the latest update...
A comprehensive study in the journal Science published June 15 2023, concluded that five key shark species are in serious decline and at higher risk of extinction. A team of 150 researchers surveyed almost 400 reefs around the world, and discovered that populations of these sharks suffered staggering declines of between 60 percent to 73 percent ...
Sharks have roamed the ocean since before dinosaurs walked the earth. But today, around a third of the world’s 500+ shark species are threatened with extinction. New research co-authored by Riley Pollom of the Seattle Aquarium offers a way forward.
More than one-third of all sharks, rays, and chimaeras (fish related to sharks and rays) are now at risk of extinction because of overfishing, according to a new study re-assessing their IUCN Red List of Threatened Species extinction risk status.
Scientists say sharks and rays are disappearing from the world's oceans at an "alarming" rate. The number of sharks found in the open oceans has plunged by 71% over half a century, mainly due...
(7 Sept 2021) A major study re-assessing the IUCN Red List status for all sharks, rays and chimaeras reveals that over 1/3 of all these species are now at risk of extinction caused by overfishing. Governments and regional fisheries bodies must act now to stop overfishing and prevent a global extinction crisis.
We estimate that two-thirds of coral reef sharks and rays are threatened with extinction, based on the observed number of threatened species combined with the estimated number of Data Deficient...
