Sharks thrive in healthy corals

Down to Earth - - SCIENCE -

SHARKS BE­COME abun­dant in a co­ral zone when the reefs are healthy. In a decade­long study con­ducted in the Great Bar­rier Reef, re­searchers used thou­sands of re­mote un­der­wa­ter video sta­tions to count the num­ber of sharks. The re­sults showed that the health of co­ral reef had a huge af­fect on abun­dance of shark, es­pe­cially the grey reef shark which is found on co­ral reefs. The study un­der­lines the im­por­tance of co­ral reefs in pro­tect­ing sharks. PLoS One, Septem­ber 10
