Credit: NOAA Fisheries Diverse benthic habitat, showing brittlestars, a crinoid, and stylasterid corals of the genus Stylaster. Stylasterid (Stylasteridae) corals are among the most important habitat-forming invertebrates in deep-sea coral ecosystems in the North Pacific. They are also known as ‘lace corals’ or ‘hydrocorals’. Like their warm water cousins the stony coral, found in coral reefs, they have rigid skeletons made of calcium carbonate. Credit: NOAA Fisheries

A sea floor of soft sediment covered in venus flytrap sea anenomes and other invertebrates such as brittle stars. Credit: NMFS/NOAA One of the more common seafloor habitats in the Gulf of Alaska is sand and mud. These soft sediment habitats are home to the venus flytrap sea anemone (Actinoscyphia aurelia) and other invertebrates such as this great armored brittle star (Stegophiura ponderosa). Many of the organisms in these habitats are passive suspension feeders that orient themselves into the current to capture passing organic particles as they drift by. Image courtesy of NMFS, NOAA.

“A Better Chance for Resilience”: Using Hungry Fish to Conserve Coral Reefs

NOAA Fisheries scientist Tye Kindinger explains how identifying the best algae-grazing fish in the Pacific region can help fight against algae overgrowth and promote recovery of distressed coral reefs.

These fish use their bird-like beaks to scrape away seaweed, or algae, on reefs. Larger parrotfish remove small amounts of underlying substrate, which creates new spaces for corals to grow.
