Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 7.7 cm SL (female)
Rayons mous dorsaux (Total) : 6 - 7; Rayons mous anaux: 4 - 5. Escal bulb without membranous anterior crest. Distal escal appendage an elongate, cylindrical stalk, with a slender, elongate prolongation emerging anteriorly from bases of escal hooks, bearing numerous lateral serrations or filaments. Posterior escal appendage laterally compressed and rounded (Ref 27827). Length of illicium 39-46%; posterior escal appendage a compressed flange, length 1.4-4.4% SL, with irregularly rounded edge and broad base, emerging from below escal pore; escal hooks black, relative length of medial (largest) hook decreasing with age from about 10.3% SL in 30mm specimen to 3.6% SL in 77mm specimens (Ref. 86949).
Feeds mainly on fish and occasionally on invertebrates (Ref. 27828).
