Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm SL mâle / non sexé; (Ref. 48637)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 64 - 70; Épines anales: 0; Rayons mous anaux: 51 - 47; Vertèbres: 40 - 41. Body mottled brown with irregular dark and pale markings; 2-3 dark-edged ocelli along lateral line pectorals blackish distally; dorsal and anal fins with minute black dots; caudal fin with black spots (Ref. 6270). Gill rakers rudimentary (Ref. 1602).
Inhabits coral heads of lagoon and seaward reefs; common in shallow caves or under ledges and can lie flat against vertical rock surfaces (Ref. 1602, 48637). Found in rubble slopes in sand or fine-rubble patches (Ref. 9792). Benthic (Ref. 58302). Comes out at dusk and hunts on low reef. It has low profile and crawls along like a flatworm, but activity waves its black pectoral fin as it goes (Ref. 48637). Feeds on small benthic animals (Ref. 9792).
