Distinguishing characteristics of metamorphosed female: tiny illicium, reduced to a small remnant; dorsal midline of the trunk with 2 club-shaped caruncles just anterior to soft dorsal-fin origin. Metamorphosed males: longer anterior pair of lower denticular teeth compared to posterior pair; larvae, males and juvenile females have subdermal pigment on gill cover, dorsal surface of trunk and caudal peduncle (Ref. 86949).
