Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 12 - 13; Raggi dorsali molli (totale) : 7 - 10; Spine anali: 3; Raggi anali molli: 4 - 6; Vertebre: 28. Lack scales (Ref. 33616).
Occur in inshore waters (Ref. 9563). Most active at night, lying motionless during the day. Spawn during August-September and seem to be triggered by an increase in water temperature at the onset of spring. Smaller individuals feed mainly on shrimps and crabs, while bigger ones are piscivorous (Ref. 2156). Adults possess venomous infraorbital, preopercular and dorsal-fin spines (Ref. 33616).

Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.3 se; based on diet studies.
Generation time: 9.4 ( na - na) years. Estimated as median ln(3)/K based on 1
