بوم شناسي
دريايي; تغييرات عمق 0 - 550 m (Ref. 11333). Tropical; 10°N - 6°S

Size / Weight / سن
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL جنس نر / بدون خواص جنسي; (Ref. 11333); 12.5 cm SL (female)
شعاع نرم باله پشتي (کل) : 25; شعاع نرم باله مخرجي: 38; مهره ها: 68. Two terminal bulbs separated by a short interspace, 0.4-1.6 times the length of distal bulb. Barbel length short 37-44% SL in specimens over 8 cm SL. Three to 9 short, usually bulblet-tipped filaments and 2 long ones, arising together from distal end of distal bulb or from a short stem. Longest filament becoming 23-35% SL in specimens larger than 8 cm; 1 long filament with a prominent large bulblet. Distal bulb 1.2-2.5 times length of proximal-bulb. Axis of stem well pigmented; between bulbs variably pigmented, sometimes forming a dark spot or small cap at proximal end of distal bulb. External chevron-shaped or roundish striated areas usually unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8 (Ref. 11333).
