Morphology | Morphometrics
soft rays: 4. This species is distinguished by the following characters: pectoral fin-rays 10-11; dorsal-fin rays 18-19; body rings 15-16 + 13 or total 46-47; snout length 2.8-3.2 in HL; lateral trunk ridge ending on penultimate trunk ring; absence of spine-like projections on principle tail ridges; when alive, colour generally pinkish red (Ref. 116662).
Occurs in exposed coral reef slopes and generally encountered solitarily or in pairs at depths of about 10-25 m. It exhibits highly effective camouflage with regards to its shape and colour, closely matching an unidentified, short tubular sponge among which this fish is invariably found (Ref. 116662).
