The National Oceanic and Atmospheric Administration (NOAA) Fisheries Service announced in November a proposal to list 66 coral species, such as the elkhorn coral (Acropora palmata) pictured above, as either endangered or threatened under the Endangered Species Act of 1973 (ESA). Fifty-nine of the coral species are found in the Pacific while seven are found in the Caribbean.
Climate change and ocean acidification are the leading threats to coral species, according to a biological review team convened by NOAA to assess the status of coral species in U.S. waters.
Elkhorn coral is already listed as threatened under the ESA. But disease, bleaching events—when corals lose the symbiotic algae that gives them their color—and low genetic diversity are pushing this species into further declines, prompting the proposal to bump its status to endangered.

Found in the Caribbean (map), pillar coral (Dendrogyra cylindrus) is unusual because the polyps come out during the day to feed, giving this species a fuzzy appearance. Many coral species usually feed at night. NOAA's Fisheries Service is proposing to designate pillar coral as endangered under the ESA due to habitat decline.
Branching corals (Acropora spp.) are found in the Atlantic ocean, the Caribbean, the Gulf of Mexico, and the Indo-Pacific region. NOAA has proposed two species in the Caribbean for endangered status, including the staghorn coral (Acropora cervicornis), while 19 species in the Indo-Pacific area are proposed for threatened status.

Will Japanese Ban on Taiji Dolphins Stop Notorious Hunts?
Several Japanese zoos and aquariums voted last week to stop buying and selling dolphins taken during the notorious Taiji roundup, made infamous in the Oscar-winning documentary, The Cove. Yet animal advocates are dubious that it will stop the slaughter.
