Gorgonia spiralis Linnaeus, 1758 (by subsequent designation: Brook, 1889 ). Diagnosis. “Antipathids having an elongate unbranched corallum, around which the polyps are distributed subspirally in several irregular rows, never in a single linear series. The zooids are usually rounded in outline, and are provided with six tentacles arranged in a radiate manner. The mouth is situated on a more or less prominent conical projection of the peristome, which may show a constriction at its base. There are five pairs of mesenteries in the oral cone and three below. The coenenchyme consists of the tissue uniting neighbouring zooids; it contains a system of canals which takes a direction chiefly at right angles to the axis of the stem, and communicates with the bases of the individual zooids” ( Brook, 1889 ). Distribution. Cosmopolitan (Dana, 1846; Brook, 1889 ; Van Pesch, 1914 ; Zou & Zhou, 1982 ; Echeverría, 2002 ).
