Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 58 - 63; Anal spines: 0; Anal soft rays: 48 - 52; Vertebrae: 66 - 69. Light to dark brown with color, sometimes with dusky crossbars (Ref. 4395). Middle lateral line joining with the dorsal lateral line just above the pectoral fin base; midline of parietal canal with a single pore; dark spot above pectoral fin (Ref. 531). Pelvic fin rarely absent; dorsal and anal fin membranes united only basally to caudal fin (Ref. 49841).
Body shape (shape guide): eel-like; Cross section: circular.

Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.3 ±0.58 se; based on food items. |
|
Resilience (Ref. 120179) |
Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
Low to moderate vulnerability (29 of 100). 🛈 |
