Short description Morphology | Morphometrics

Dorsal spines (total): 20; Dorsal soft rays (total): 9-11; Anal spines: 2; Anal soft rays: 7 - 21. This species is distinguished from its southwestern Atlantic congeners by the following set of characters: D XX,9-11 (rarely XIX or XXI); A II,17-21; pectoral-fin rays14-15 (rarely 13); length of third pelvic-fin ray contained 2.5 to 3.0 times in second pelvic-fin ray; lateral-line scales 48-56; total nuchal cirri 24-36; pectoral-fin base and midline before dorsal-fin no scales; breast usually fully scaled in males, often naked in females; pores 2-3 from preopercular canal onto opercle. Colouration: pattern dominated by 5-6 (rarely 7), saddle-like bars on body, extending to spiny dorsal fin (Ref. 123106).

Biology     Glossary (e.g. epibenthic)

Occurs in shallo reefs (Ref. 123106), on sandy bottoms and Thalassia testudinum beds (Ref. 13628). Feeds mainly on crustaceans but also on gastropods and worms (Ref. 13628).

Estimates based on models

Preferred temperature (Ref. 123201): 24.1 - 28.1, mean 27.3 °C (based on 722 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00290 - 0.01252), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.49 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 4,000).
