Grapevine dragonfish (Eustomias bulbornatus) fish species information

Scientific Name
Eustomias bulbornatus

Common Name
Grapevine dragonfish

Biology
Dorsal spines (total): 0; Dorsal soft rays (total): 22-26; Anal spines: 0; Anal soft rays: 32 - 37. A single, very small terminal bulb 0.3-0.6% SL. Barbel short 20-35% SL in specimens over 8 cm and some smaller ones, shorter in some developing specimens up to about 8 cm. Three pairs of short filaments; each filament of 1 pair with a prominent, elongate distal bulblet that may be larger than the terminal bulb; a pair slender , with closely spaced very small bulblets; a pair simple, with few or no occlusions, and usually the longest. Axis of stem moderately pigmented, becoming darker before bulb and very dark over 1 side of bulb, where pigment forks and extends along axis of the pair of filaments with large bulblets. External chevron-shaped or roundish striated areas unpigmented. Dorsal paired spots between occiput and dorsal-fin origin 9 or 10 (rarely 7 or 8) (Ref. 11333).
