Western Atlantic: Maryland in the USA, Bermuda and Bahamas to Rio de Janeiro, Brazil (Ref. 13628), including the West Indies (Ref. 3802); absent in the northern Gulf of Mexico.

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 31 - ? cm

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 2; Anal soft rays: 9. Adults uniformly blue, with yellow area on top of head that disappears in larger fish. Large fish develop prominent bulging snout and extended upper and lower caudal fin lobes. No other species has this uniform blue color in adults. (Ref. 26938).

Biology     Glossary (e.g. epibenthic)

Inhabits coral reefs. Juveniles found on Thalassia beds (Ref. 13628). Feeds on benthic plants and small organisms in the sand (Ref. 5521). Forms large spawning aggregations (Ref. 9710).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing during breeding (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 26.1 - 28.2, mean 27.4 °C (based on 685 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00726 - 0.02285), b=3.04 (2.89 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Generation time: 3.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
