Now considered a seperate species to S. variabilis, previously reported, which has a Brazilian distribution, rather than in Northern Caribbean
Adult: Highly variable. Body greenish-grey to charcoal washing over yellowish undercolor - with paler belly and signs of dark diagonal bands. Younger aduts may have dark spot to rear of dorsal fin (variable). Scattering of blue spots on head rarely extend onto body (cf Beaugregory, S. leucostictus)
Juveniles: Large ocellus (black with blue border) on rear dorsal fin which does not extend onto body (cf Beaugregory, S. leucostictus). Dark spot at base of dorsal fin, which often disappears as the juvenile grows towards adulthood. Blue lines along snout overlying dark/ blueish upper body, with yellow lower body without (clean) spots extending onto yellow.
Adults inhabit shelterd reff habitats. They feed mainly on benthic algae but also on sponges, ascidians and anemones, whilst juveniles feed on invertebrates like harpacticoid copepods and nemerteans. Often solitary. Juveniles are aggressively territorial. Aggressive when breeding.
Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs
