Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12-14; Anal spines: 0; Anal soft rays: 10 - 12. Dorsal part of body without prickles, belly covered with prickles (Ref. 559). Greenish or dark grey above, silvery white below (Ref. 4919). Distinguished from other Lagocephalus species by the black gill opening (Ref. 559).

Biology     Glossary (e.g. epibenthic)

Found in the shelf edge (Ref. 11230). Closely resembles the Atlantic species L. laevigatus Linnaeus which reaches southern Angola (Ref. 4919).

Estimates based on models

Preferred temperature (Ref. 123201): 16.6 - 28.3, mean 26.4 °C (based on 1313 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02692 (0.01730 - 0.04187), b=2.86 (2.74 - 2.98), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.4 se; based on size and trophs of closest relatives
Generation time: 2.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (K=0.53).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100).
