Max length : 10.0 cm SL male/unsexed; (Ref. 4967); max. reported age: 6 years (Ref. 7248)

Environment

Pelagic-neritic; amphidromous; freshwater; brackish; marine

Climate / Range

Subtropical; 25°S - 36°S, 17°E - 34°E (Ref. 188)

Africa: Lake Piti, Mozambique along southern African coast to Saldanha Bay, possibly mouth of Orange River (but perhaps confused by presence of a second undescribed species). Reported occurrence in India (Ref. 32693) needs validation (Ref. 33664). Reports of the occurrence in Madagascan waters (Ref. 13333) are in error (Ref. 33664).

Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 18; Anal spines: 0; Anal soft rays: 16 - 27. With 6 to 9 unkeeled pre-pelvic scutes, followed by an equally thin pelvic scute, all with slender ascending arms; no post-pelvic scutes. Snout pointed, lower jaw a little prominent, with a single row of fine teeth in each jaw; second supra-maxilla paddle-shaped. Gill rakers small but present on posterior face of third epibranchial (cf. absent in Ehirava fluviatilis).

Occurs primarily in estuaries and lagoons, but also found in lakes and rivers. Entire life cycle is completed in the estuary (Ref. 32693). Can tolerate salinities under 4 ppt and of up to 52.6 ppt (Ref. 32693). Breeds throughout the year with a peak in spring and early summer. Maturity may be attained within the first or second year and an age of up to 5 or 6 years is recorded. Feeds chiefly on zooplankton by filtering or selecting individual organisms from the water column (Ref. 7248). Utilized fresh or dried and salted (Ref. 12484).
