Short description Morphology | Morphometrics

Dorsal spines (total): 7 - 8; Dorsal soft rays (total): 8-9; Anal spines: 1; Anal soft rays: 9 - 10. Diagnosis: 19-22 predorsal scales; 28-33 scales in longitudinal series (including 2 or 3 scales on caudal fin base), 10-12 in rearward transverse series; 1st dorsal fin: VI-VII; 2nd dorsal fin: I,8-9; anal fin: I,9-10; pectoral fins: 12-14; caudal fin rounded with 15 segmented rays, 13 of which are branched; sensory canals absent on head; about 10 gill rakers on upper limb, and 20 on lower limb of first gill arch (Ref. 57413). Coloration: Preserved specimens: brownish dorsally on head and body; ventral surface of belly pale; black pigment on scales along lateral midline of flanks; about 2 longitudinal bands sometimes present just dorsal to midline of scales; dark brown or black spot just posterior and dorsal to operculum, and sometimes a smaller spot below this; vertical brown bar at base of caudal fin; dorsal and caudal fins covered with black spots forming 2-3 longitudinal bands on both dorsal fins, and several vertical, crescentric bands on caudal fin; anal fin light brown, pelvics light brown with central rays sometimes darker; pectorals transparent (Ref. 57413). Live specimens: pale olive-green on back and white on belly; red-brown spots on 1st dorsal, 2nd dorsal and anal fins, latter 2 also with light yellow spots near distal margin; caudal fin with red-brown spots near base, and yellow or orange spots posteriorly (Ref. 57413).

Biology     Glossary (e.g. epibenthic)

Inhabits brackish water estuaries, creeks, lagoons and mangrove areas; occasionally enters freshwater (Ref. 7391, 57413). Known to be tolerant of wide range of salinity. Used as bio-control agents, e.g., use in control of mosquito larva (Ref. 42628). Endemic to West African coastline from Senegal to the Cunene River in Namibia (Ref. 92840).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Spawns in caves or on top of plants. Sometimes several females spawn with one male.

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 23.4 - 27.9, mean 26.5 (based on 64 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00424 - 0.02467), b=3.06 (2.85 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.5   ±0.23 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (20 of 100) .
