Western Central Atlantic: Bahamas and Florida, USA to Curaçao (Ref. 5521). Caribbean, including Antilles (Ref. 26938).

Biology     Glossary (e.g. epibenthic)

Inhabits small patch reefs surrounded by white sand (Ref. 5521). Observed primarily on dead surfaces of elkhorn coral (Acropora palmata), but significantly more males than females were found on live coral surfaces. Males occurred twice as frequently as females in the vacated constructed tubes of serpulid worms or vermetid mollusks that provided greater surface for egg deposition (Ref. 47880). Feed mainly on planktonic calanoid copepods (Ref. 94105).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00187 - 0.01169), b=3.08 (2.86 - 3.30), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (tmax=4 (aquarium)).
Vulnerability (Ref. 59153):  Low vulnerability (22 of 100) .
Price category (Ref. 80766):   Unknown.
