Morphology | Morphometrics
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 of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00177 - 0.01179), b=3.10 (2.87 - 3.33), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
