Tag: Black-Fin Sandperch (Parapercis Snyderi)

When i first saw this Sandperch, i assumed it must be a juvenile Yellow-Bar Sandperch (Parapercis Xanthasona). However, i'm now becoming quite confident that it is actually a different species, with the most likely candidate being the Black-Fin Sandperch (Parapercis Snyderi).

This species appears to vary considerably with the main area of variation being the dark bars on the back. Also, the first dorsal fin may vary from black, to a dark yellow colour.

Another distinguishing feature is the presence of a "pearly" line both below the eye, and also at the side of the snout (in the few photos i have so far, these pearly lines have been difficult to distinguish).

Other characteristics which ARE present include the 5 or so black/brownish "double dash" marks on the body, yellow spots along the lower body and numerous red/yellow/orange spots, intermingled with small white spots on the caudal fin.

This is the best profile shot of what i now believe could be a Black-Fin Sandperch (Parapercis Snyderi).

Although i have seen photos showing this species with much darker bands on the upper body, there also appears to be a paler variation, very similar to this.
