Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11 - 13; Spine anali: 0; Raggi anali molli: 17 - 21. Preopercular series with 6 large neuromasts; male with orange-red spot pattern in dorsal and anal fins; caudal fin orange-red; female with spotted head, body and unpaired fins (Ref. 42930).

Found usually at the surface of pools preying on small food items (e.g. small insects) that fall on the water surface. These pools from which the species were collected are ephemeral and usually dry up seasonally (Ref. 42930).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01096 (0.00449 - 0.02680), b=2.92 (2.71 - 3.13), 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

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