Abstract

Michael Grant studied the conservation status of sharks and rays that rely on freshwater and estuaries (non-marine environments) during their life cycle. He found that most species are facing high extinction risks, and that remote nations such as Papua New Guinea may offer a refuge for some species. Greater conservation efforts are now required to prevent extinctions across non-marine sharks and rays, and global organisations are using the results of this study to guide future allocation of conservation resources.
