ABSTRACT: The shortbodied blenny Exallias brevis is an obligate corallivore. Studies on Hawaiian reefs and casual observations on other Pacific reefs reveal that E. brevis feeds on a wide variety of scleractinian corals, including the hydrocoral Millepora spp. This blenny produces distinctive circular feeding marks of ca. 2 cm2 on corals; the marks can persist for 50 d or more. E. brevis is indigenous to the Red Sea and may be responsible for the multifocal bleaching syndrome in Red Sea Millepora dichotoma described by Zvuloni et al. (2011; Mar Ecol Prog Ser 441:25−32).
