Watch: More than half of all shark species could go extinct in a century

Great white sharks may be one of the most powerful apex predators of our seas, but they are not invincible. According to new research, great whites are among the one-third of all marine megafauna species that face the risk of extinction over the next century. Under worst-case scenario projections, 62% of shark species would be lost.

While sharks are the “most threatened marine vertebrate group in the world,” according to researchers, they aren’t the only animals in danger. Other at-risk species include sea turtles, dugongs, and giant clams.
