Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 17 - 19; Raggi dorsali molli (totale) : 9 - 10; Spine anali: 3; Raggi anali molli: 7 - 8. Diagnosis: The presence of predominantly tricuspid teeth in both the upper and lower jaws that are visible when the mouth is closed clearly places Petrotilapia microgalana in the genus Petrotilapia (Ref. 78421). Pigmentation and colour patterns of P. microgalana distinguish it from all described species of Petrotilapia; the black submarginal band in the dorsal fin distinguishes P. microgalana from P. tridentiger and P. chrysos; males of P. microgalana have a bright blue ground colour along the flanks with 5-7 faint black vertical bars and a blue head; males of P. genalutea have a dull blue ground colour laterally with orange colour along the flanks, 5-7 black vertical bars, and orange/yellow cheeks, while males of P. nigra are predominantly black with 7-10 gray/brown vertical bars (Ref. 78421).

Petrotilapia species have broad, fleshy lips with numerous slender teeth that are used to comb the algae on rocks for diatoms and loose algal strands (Ref. 6256, 87181). Adult Petrotilapia males establish territories; females, juveniles, and non-territorial males are found either singly or in schools throughout the rocky habitat (Ref. 6256). Petrotilapia microgalana males patrol territories at an average depth of 10-15 m; females are usually encountered in the upper region (Ref. 79521). It inhabits the deeper rocky environments of Lake Malawi (Ref. 87181).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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