The study, published in Nature Communications, shows that 59% of the 134 coral-reef associated shark and ray species are being threatened with extinction, making them the most threatened groups found on coral reefs alongside marine mammals.
The study says that coral reefs are among the most diverse ecosystems on earth and are home to more than 1/3 of the ocean’s fish species. And they face some of the most widespread threats to any ecosystem and are in danger due to things like climate change and coastal development.Campbell Keenan and his family were visiting Florida from Massachusetts. They were on a sport fishing charter boat off the coast of Fort Lauderdale when Keenan reeled in a catch of a lifetime.
Coral reef fisheries directly support the livelihoods and food security of over half-billion people. Still, the human footprint far exceeds the local reef productivity across a majority of the world's reefs, according to the study. "Overfishing, however, is the most immediate direct and indirect threat to most reefs, and the cascading consequences for reef ecology and dependent coastal communities are only now being revealed," the study's authors wrote. A group of people on a fishing charter off Whitianga, New Zealand, were stunned when a large mako shark leaped out of the water and landed on the front of the boat, video uploaded on Nov. 6 shows.
