Actinopterygii (ray-finned fishes) > Clupeiformes
(Herrings) > Clupeidae
(Herrings, shads, sardines, menhadens) > Ehiravinae
Etymology: Spratellomorpha: Old German, sprotte (1611) = a small fish, Clupea sp.+ greek,morphe = shape (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic. Tropical; 0° - 26°S, 37°E - 50°E (Ref. 188)
Western Indian Ocean: Madagascar and Kenya coast (Port Tudor, Mombasa; probably more widespread).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 188)
soft rays: 16 - 27. Body a little compressed, belly rounded, without pre-pelvic scutes, but a pelvic present with slender vertical arms. Snout pointed, lower jaw projecting slightly. Last two anal fin rays separate forming a distinct little finlet. This last feature identifies the species (found in no other clupeoid of the western Indian Ocean).
Presumed to be a marine or estuarine species. Apparently rare.

Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00361 - 0.02100), b=3.03 (2.82 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
