Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 9003)
soft rays: 35 - 41. Head and body peach-like orange pink, slightly paler ventrally. Adult males with a distinctive whitish streak along the belly. Distinguished from other brotulas by the dorsal fin which begins forward of the gill cover and has the first rays free of membrane.
Uncommon to locally abundant cryptic species found in areas with dense algal growth (Ref. 34024). Sometimes in rock pools (Ref. 9003).
