Blackspot Chromis, Galapagos Damsel

Body slender (greatest body depth 27-33% of SL), fusiform, compressed; head pointed, upper and lower profiles similar; 1 pair of nostrils; bone under eye hidden by scales; mouth small, protrusible, slightly oblique, opens at front; teeth in 2 rows, outer row conical; lower gill rakers 21-23; a single continuous dorsal fin, XIII-XIV, 10-12; anal rays II, 12-13; dorsal and anal fins relatively low; pectoral rays 17-18; no projecting short spines at upper and lower base of tail fin; caudal fin strongly forked; scales are moderately large and rough; 29-31 scales on lateral line; body scaled, head scaled except for area in front of eye and around nostril; basal parts of the median fins scaled; lateral line almost complete, runs along top of tail base almost to tail fin.

Grey, grading to whitish on underside of head and on belly, scale centers usually lighter; a whitish spot on upper back below soft dorsal fin; each caudal fin lobe with a blackish streak; a black blotch covering pectoral fin base.

Size: attains 16 cm.

Habitat: usually seen in open water over rocky habitats.

Galapagos Islands; the 1925 record of this species from Cocos, the only record at that island, most likely is a cataloging error relating to specimens collected in the Galapagos.

Note: This species evidently disappeared from the Galapagos during the intense El Niño event of 1982-83, when greatly increased sea temperatures had strong adverse effects on the islands marine fauna and flora. It has not been seen since then in the Galapagos and likely is extinct in those islands.
