Gray Reef Sharks (image) University of Miami Rosenstiel School of Marine & Atmospheric Science Share Print E-Mail Caption Curious gray reef sharks (Carcharhinus amlyrhynchos) at Kure Atoll in the Papahanaumokuakea Marine National Monument, Hawaii were studied as part of a study published April 25 in the journal Conservation Biology. An international team of marine scientists provide the first estimates of reef shark losses in the Pacific Ocean using underwater surveys conducted over the past decade across 46 US Pacific islands and atolls, as part of NOAA's extensive Pacific Reef Assessment and Monitoring Program. The team compared reef shark numbers at reefs spanning from heavily impacted ones to those among the world's most pristine. The results are sobering. Credit P.
