The study herein is the first to identify a definitive first host, black sea bass <jats:italic>Centropristis striata<\/jats:italic>, for <jats:italic>L. radiatus<\/jats:italic> supporting larval development to adults and sexual reproduction in the gills. This finding suggests a two-host life cycle for <jats:italic>L. radiatus<\/jats:italic>, with black sea bass as the first host. Heavy infections in the gill were associated with considerable pathology related to a unique and invasive attachment process that penetrated the gill and selectively attached to the gill filament cartilage. The morphology of the developing copepod was highly conserved with that of a related pennellid copepod, <jats:italic>Lernaeocera branchialis<\/jats:italic>, though was distinguished by the attachment process, unique pigmentation and other morphologic features described herein. Sequencing the small and large subunits of the ribosomal RNA and mitochondrial cytochrome c oxidase subunit I genes demonstrated <jats:italic>L. radiatus<\/jats:italic> to share closer identities with <jats:italic>Lernaeocera<\/jats:italic> and <jats:italic>Haemobaphes<\/jats:italic> spp. pennellid copepods rather than other <jats:italic>Lernaeenicus<\/jats:italic> spp. available in GenBank to date.
