Extinction risk and the spatial patterning of shark, ray and chimaera richness, including hotspots of coastal and deepwater richness, for wide-ranging and endemic species.
Sharks & rays are sentinels of ocean health.
- Global abundance has been fished down by 65%,
- Now 37.5% of species are threatened,
- The current extinction rate is 25–250 times greater than the background fossil record, with greatest losses in tropical coastal seas. #BiodiversityTargets
