Etymology: Malacoctenus: Greek, malakos = soft + Greek, kteis, ktenos = comb (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 40 m (Ref. 13121), usually 0 - 3 m (Ref. 9710). Subtropical; 32°N - 26°S, 100°W - 32°W
Southwestern Atlantic: from Bahamas and Florida southwards to Brazil.

Morphology | Morphometrics
(total): 20 - 21;
soft rays: 20 - 22. With 3-5 dark brownish-red bands in form of inverted triangles along side. No other labrisomid has this distinctive color pattern (Ref. 26938). Head with a few small dark spots; bars on body sometimes not very dark but outlined by dark bars; scattered dots then often present elsewhere on the body (Ref. 13442).
Inhabits coral reefs and rocky shores. Often found in crevices, or among weed and rubble (Ref. 13121). Feeds on crustaceans (Ref. 13628).
