Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 13 - 18; Raggi dorsali molli (totale) : 8 - 10; Spine anali: 3; Raggi anali molli: 6 - 9. Diagnosis: The moderately sloped head, swollen rostral tip of the neurocranium, isognathous jaws, and the presence of bicuspid teeth in the outer rows of the jaws place this species in Maylandia (Ref. 27596). The red dorsal fin in combination with black bars on a blue ground colour distinguish this species from all other members of the genus except for Maylandia emmiltos, which also has a red dorsal fin; Maylandia pyrsonotos differs from all the other red top BB forms in that the vertical black lateral bars infiltrate the proximal portion of the dorsal fin (Ref. 27596).

Found at rocky shores (Ref. 27596).

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=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
