Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); jimcraddocki: Named for Dr. James E. Craddock of the Woods Hole Oceanographic Institution in recognition of his many contributions to our knowledge of deep-sea fishes (Ref. 51076).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 809 m (Ref. 51076). Deep-water; 41°N - 26°N

Max length : 14.3 cm SL male/unsexed; (Ref. 51076)
Morphology | Morphometrics
soft rays: 40 - 41. Two pectoral rays (one as tiny rudiment), and a barbel with three branches arising proximal to midlength of the stem, followed by two ovoid swellings (bulbs), either contiguous or separated, and a large terminal bulb. The tear-shaped terminal bulb larger in diameter than the stem or proximal bulbs, with the acuminate end posteriad and upturned dorsally, and bears multiple filaments and bulblets in two groups, one at its anterodorsal surface and one at its terminus. Barbels relatively short (<= 20% standard length) (Ref. 51076).
Probably undergoes some form of vertical migration from below 500 m during the day and within the upper 100 m at night (Ref. 51076).
