Analysis of seawater for DNA of rare and endangered hammerhead sharks has been used to infer their presence or absence at multiple locations throughout their range. No sharks were captured or observed; accuracy of the inferred distributions depends on the presumed degradation of environmental DNA in hours or days.

In the Caribbean, Hammerhead #Sharks Return to School https://hakaimagazine.com/news/in-the-caribbean-hammerhead-sharks-return-to-school/ paper: https://www.frontiersin.org/articles/10.3389/fmars.2024.1347285/full

"Seeing one of these critically endangered #animals is a thrill, but seeing nearly a dozen plying the water side by side is worth writing home about. This was especially true for Mauvis Gore and her colleagues when, in 2022, they saw a group of scalloped hammerheads off the #CaymanIslands—the first time since the 1970s that #hammerheads have been seen schooling in the #Caribbean Sea."

STOP THE SILENT EXTINCTION CRISIS BENEATH THE WAVES 🌊 🦈

Over 70% of our Earth is #ocean, yet the way we are interacting with it is deeply damaging to it and the creatures that live in it.

Without drastic action, uniquely Australian #species could disappear before we even get a chance to know them. Endangered #hammerheads will still be fished in the #GreatBarrierReef, and iconic species like #sawfish may no longer cruise our coasts and rivers.

Save Our Endangered Sharks & Rays.
