Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 10; Spine anali: 1; Raggi anali molli: 10. Diagnosis: posterior tip of upper jaw extending to below posterior margin of eye or beyond (Ref. 57403), 79590). 63-136 long, slender, unicuspid setiform teeth on each half (left and right) of upper jaw, with alternate teeth usually staggered in 2 rows (although it may be difficult to easily distinguish these rows as separate)(Ref. 79590), not separated by median tubercle (Ref. 57403, 79590).

Larvae ascend rivers, adults in freshwater (Ref. 4343). Amphidromous endemics living as adults in clearwater streams of the volcanic islands in the Gulf of Guinea and of Mount Cameroon streams in Western Cameroon (Ref. 92840).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this 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).
