    Ocean heat waves are becoming more common and lasting longer

    The world’s oceans are sweltering. Over the last century, marine heat waves have become more common and are lasting longer. New research suggests the annual number of days that some part of the ocean is experiencing a heat wave has increased 54 percent from 1925 to 2016, researchers report April 10 in Nature Communications.

    Typically, scientists define a marine heat wave as at least five...

    Corals are severely bleaching five times as often as in 1980

    Corals are in hot water.

    Severe bleaching events are hitting coral reefs five times as often as in 1980, researchers report in the Jan. 5 Science.

    Scientists surveyed 100 coral reef locations in tropical zones around the world, tracking each spot’s fate from 1980 to 2016. At first, only a few of the locations had experienced bleaching. But by 2016, all had been hit by at least one...

    Fluorescence could help diagnose sick corals

    Sickness makes some corals lose their glow.

    Disease reduces a coral’s overall fluorescence even before any sign of the infection is visible to the naked eye, a new study finds. An imaging technique that illuminates the change could help with efforts to better monitor coral health, researchers report November 6 in Scientific Reports.

    Many corals naturally produce fluorescent...

    Big slimy lips are the secret to this fish’s coral diet

    View the video

    Tubelip wrasses eat dangerously, daring to dine on sharp corals lined with stinging cells. New images reveal the fish’s secret to safe eating: lubing up and planting a big one on their dinner.

    “It is like sucking dew off a stinging nettle. A thick layer of grease may help,” says David Bellwood, a marine biologist at James Cook University in Townsville, Australia, who...

    Coral die-off in Great Barrier Reef reaches record levels

    Tourists planning a visit to northern portions of the Great Barrier Reef should be prepared for some sad sights. On average, two-thirds of the nearshore coral in the mostly pristine area north of Port Douglas, Australia, has been pronounced dead by scientists who have surveyed the reef. It’s the largest coral die-off ever recorded in Great Barrier Reef history, researchers from the ARC Center...
