Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 80 - 86; Anal soft rays: 51 - 59; Vertebrae: 43 - 44. The species is characterized by the following: vertebrae 13 + 30-31 = 43-44, dorsal fin rays 80-86, anal fin rays 51-59; snout is terminal to slightly inferior; eye small 1.4-1.6 % SL; pectoral fin length 9.5-9.9 % SL; scales absent on head and body; posterior nostril moderately small, more than half the size of eye; lower preopercular pore 1, small; weak ventral spine on maxilla positioned behind rear of eye; single pair of pseudoclaspers dorsally curved at their distal ends, thin, about half the length of penis (Ref. 57886).

A recently caught female specimen from Bird Island, Algoa Bay (SAIAB 70867) was found to be gravid at 54 mm SL with four 20-23 mm SL, fully developed embryos; their preserved coloration is uniformly light brown, slightly darker than their mother (Ref. 57886).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
