Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 11; Anal spines: 0; Anal soft rays: 7 - 8. Rose-pink in color, becoming scarlet on tail and fins. Pink with yellowish tinges ventrally. Deep reddish patch over most of body dorsally. Distinguished from other clingfishes by a broad, bluntly pointed head, with a thick, fleshy upper lip, no longitudinal groove below the eye but a line of papillae is usually present. The sucking disc has flattened papillae continuous across the anterior margin.
Inhabits sheltered areas beneath rocks of the intertidal at mid to low tide level. Also found in subtidal areas. Feeds on small crustaceans and mollusks.
