Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri
Eastern Central Atlantic: Senegal to Gabon; also Cape Verde, São Tome-Principe Islands, and Rolas Islands. There is little doubt that only a single species of Lethrinus exists in the tropical western Atlantic.
Found in shallow coastal waters (Ref. 2263). Feeds mainly on bottom-dwelling invertebrates. Marketed fresh (Ref. 171), smoked and dried salted (Ref. 2295). Abundant during the winter months (Ref. 2683).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01849 (-0.09671 - 0.13369), b=2.96 (2.89 - 3.03), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.5 ±0.46 se; Based on food items.
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2).
Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100) .
