Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 20. Trunk rings 12; tail rings 37; subdorsal spines 4/0,1,1,1,1; nose spine moderately large, height about equal to pupil diameter; double spine above eyes moderately long, slightly longer than pupil diameter; lateral head spine double and large; coronet slightly raised; gill openings extending upwards, almost joined at neck ridge; shoulder rings confluent over neck-ridge forming continuous collar (Ref. 42735).
Body shape (shape guide): other.

Biology     Glossary (e.g. epibenthic)

Probably pelagic (Ref. 42735). Maximum length is based on a straight-line length measurement from upper surface (ignoring spines) of first trunk ring, to tip of tail (Ref. 42735). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
