Maturity: Lm ?  range ? - ? cm
Max length : 56.0 cm TL male/unsexed; (Ref. 54826); 61.0 cm TL (female)

Short description Morphology | Morphometrics

Vertebrae: 98. Diagnosis: Four dark saddles, more or less equally distributed along the head and body. Relatively small, dark pigmented dorsal fins, each with a white distal streak. Large pectoral fins. Unique egg case, with 2 long tendrils extending from its base and flanges with 2 turns. This species differs from H. japonicus in having 4 dark saddles (vs. 11-14); a smaller first-dorsal fin (9.3-10.9% TL vs. 11-21% TL); an egg case of 2 turns (vs. 3), bearing extremely long tendrils (vs. short) (Ref. 54826).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5059   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00166 - 0.00872), b=3.15 (2.95 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
