Almost two out of every three shark or ray species living in coral reefs are at risk of disappearing from the world forever

The alarming study has just been published in  Nature Communiciations.       It finds, except for marine mammals, these coral sharks and rays are more likely to go extinct than any other wildlife group in th e world. The usual culprits behind this tragic state of affairs have, once again been found to be; overfishing, habitat loss and climate change. Bluespotted lagoon ray. Photos by Colin Simpfendorfer. There is a glimmer of hope amid the findings. The ray (above) is the only coral reef shark or ray with an increasing population trend.

A long-term assessment of theYangtze finless porpoise in a heavily mined lake in China, has made some disturbing discoveries. Sand mining boats, similar to those in Poyang Lake. Photo by Zhigang Mei. In only a decade, the mining has significantly restricted the porpoise’s habitat, compromised its population connectivity, and destroyed its nearshore habitats.                                               The researchers hope their findings will promote government accountability and raise general awareness of the plight of the animal.

Sand has for some time been second only to water as the planet's most heavily extracted resource, with huge implications for habitat and biodiversity health. The findings of the research team from the Chinese Academy of Science are now published in the proceedings of the Royal Socie
