Size / Weight / Age

Maturity: L m   ?   range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 188 )

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12-18; Anal spines : 0; Anal 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).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00891 (0.00371 - 0.02139), b=3.03 (2.83 - 3.23), 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. 69278 ):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100) . Price category (Ref. 80766 ):   Low .
