Diagnostic Description
provided by CoralReefFish
Diagnosis: The larvae of all Sparisoma may well be identical, and DNA sequencing is required to identify species. Transitional recruits develop the basic markings probably shared by all members of the genus, but small juveniles of Sparisoma acquire distinct patterns that separate most, if not all, regional species. S. chrysopterum and S. rubripinne may have a similar appearance as juveniles.

Comprehensive Description
provided by CoralReefFish
Description: This type shares the characteristic markings of larval and transitional Sparisoma. Recruits become distinct from S. radians and S. viride as melanophores extend onto the base of the caudal fin and divide the light bar on the tail. The tail melanophores extending into the caudal bar are roughly equal both above and below the midline and the bar is still clearly white. Juveniles are variably marked, but typically develop an alternating pattern of white and dark bars.

Diagnostic Description

Young adults with black saddle-shaped markings at upper end of pectoral fin base; often vague, pale saddle-shaped area on top of caudal peduncle; and dorsal, anal, and pelvic fins red or orange (Ref. 26938).

Life Cycle
provided by Fishbase
Although protogyny was propossed for this species (Ref. 27876), probably because testicular characteristics showed a secondary characteristic of sex-changed males, observations of overlapping size ranges of males and females, and males maturing at the same ages and sizes as did females, strongly suggest gonochorism (Ref. 103751).

Trophic Strategy
provided by Fishbase
Occurs in coral reefs and adjacent habitats, the young especially in seagrass beds. Juveniles or primary-phase adults rapidly assume a mottled pattern with which they blend with the substratum when they come to rest on the bottom. Feeds on benthic algae and seagrasses. Herbivore (Ref. 33499, 57616).

Sparisoma chrysopterum
provided by wikipedia EN
Sparisoma chrysopterum (common names: redtail parrotfish, blue parrotfish, kwab, pink kwab, pink parrot, blisterside, and blue black-finned chub)[1] is a species of parrotfish.[3]
Description
The upper end of the pectoral fin base shows black saddle-shaped markings while they are young adults. Commonly, there is a light, saddle-shaped area on top of caudal peduncle. The dorsal, pelvic, and anal fins are orange or red in colour.[2]
Juvenile specimens or those in the initial phase have a mottled pattern similar to the substratum. This provides camouflage when they rest on the sea floor.[2]
Distribution
This species lives in the western Atlantic Ocean from Brazil in the south, north to Florida and the Bahamas. It also occurs throughout the Caribbean Sea.[2]
Diet
Sparisoma chrysopterum This species grazes on seagrasses and algae growing in the benthic zone.[2]
Parasites
This species is known to host an ectoparasite in the genus Caligus named Caligus atromaculatus (C.B. Wilson, 1913).[3]
Species description and taxonomy
Sparisoma chrysopterum was first described as Scarus chrysopterus in 1801 by the German naturalists Marcus Elieser Bloch (1723-1799) and Johann Gottlob Theaenus Schneider (1750-1822) with the type locality given as "tropical western Atlantic".[4] When William John Swainson described the genus Sparisoma in 1839 he designated Sparus abildgaardi as its type species,[5] Although the specific name abildgaardi would appear to have precedence over chrysopterum, the latter is the more widely used name and the former was long mistakenly thought to be synonymous with Sparisoma viride.[6] The name Sparus abildgaardi was suppressed by the International Commission on Zoological Nomenclature and Scarus chrysopterus was recognised as the type species.[7]
