There are more than a thousand species of sharks and rays in the world, and nearly a quarter of them are threatened with extinction, according to a new study. That means these ancient types of fish are among the most endangered animals in the world.
This word comes from a Swiss-based group called the International Union for the Conservation of Nature (IUCN), which maintains the so-called Red List of species threatened with extinction.
“It’s quite bad, I’m sorry to say,” says Sonja Fordham, who helps run the IUCN shark assessment.
It’s not news that many species of shark are in trouble. But the 25 percent risk of extinction is a surprisingly large number, Fordham says, adding that “the rays are actually worse off than the sharks.”
