Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 6 - 7; Vertebrae: 10 - 16. Distinguished by the following characteristics: first dorsal VI; second dorsal I,7; anal I,6-7, pectoral rays 14-16, segmented caudal rays 17; caudal ray pattern 9/8; branched caudal rays 14-15, in 7/7 pattern; longitudinal scale count 23-25; TRB 7-8; predorsal scale count 2-9; circumpeduncular scales 12; gill rakers on outer face of first arch 2+6, 2+7; vertebrae 10+16; neural spine of second vertebra slightly expanded at tip or all pointed; body slender, compressed (Ref. 80545).

Found away from the main flow, around the edge of small pools to about 10 cm depth; seen solitary or in loose groups of 2-4 individuals, generally resting on sand or rocky substrate (Ref. 80545).

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=0.00977 (0.00442 - 0.02163), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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