Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335).
Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino pelagic-oceanic. Tropical; 12°N - 25°S
Eastern Atlantic: two records at 5°N 20°W and 11°S 11°W. Western Atlantic: Gulf of Mexico, Bahamas, and the western Atlantic from 12°N to 23°S.
Tamaño / Peso / Edad
Madurez: Lm ? range ? - ? cm
Max length : 25.3 cm SL macho / no sexado; (Ref. 4468); 17.9 cm SL (female)
Radios blandos dorsales (total) : 21 - 25; Radios blandos anales: 35 - 42. Body black, elongate and slender; depth 5-8% SL. Long, tapering protrusible snout. Slender barbel stem and two terminal bulbs. Barbel stem has little or no external pigment (Ref. 37039). Two terminal bulbs separated by a short interspace, less than half to 1.5 the length of distal bulb. Barbel length increasing to 70-91% SL in specimens 10.5-15 cm, apparently decreasing in large females (17.9-25.3 cm) to 46-51%. Terminal filament short (9% SL or less, slightly longer to 5 times longer than distal bulb) with 2 well-developed side branches arising just distal to bulb and often other branches along its length. All branches with prominent internal bulblets, some nearly the same diameter as branch, resulting in a series of swellings in many specimens. No melanophores in stem, between bulbs, or in filaments in specimens up to 15 cm SL; none between bulbs at any size. Middorsal paired spots under skin between occiput and dorsal-fin origin usually 8, sometimes 7 (Ref. 11333).
Body shape (shape guide): elongated.
Feeds on midwater fishes (Ref. 37039).
