Info
Pleurosicya carolinensis occurs in shallow reef areas on or near seagrass beds and lives in symbiosis with sponges (Larson 1990, Allen and Erdmann 2012).
The goby is not restricted to living corals (J. Williams, 2023).
Pleurosicya carolinensis was discovered and first described in the Caroline Islands archipelago, and there have since been reports of further sightings.
It is characterized by its brown to greenish body color with dense, pepper-like melanocytes, which cover the head and lower sides in particular.
It has faint dark stripes on the sides, saddle-like dark markings along the base of the dorsal fin, 23–27 longitudinal rows of scales, and no scales on the head and neck.
The goby has restricted gill openings up to the base of the pectoral fin and a relatively elongated body.
