Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 15 - 16; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 8. Diagnosis: dense black band of coloration in dorsal fin membrane (Ref. 81260).

In coastal rivers and creeks (Ref. 42576). Pair-bonding, ovophilic mouthbrooder (Ref. 52307, 81260) with delayed uptake (Ref. 81260). Spawns on open substrates; both parents brood offspring (Ref. 81260).

Both parents participate in mouthbrooding (Ref. 42576).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).

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