簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 7; 背的軟條 (總數) : 8 - 9; 臀棘: 1; 臀鰭軟條: 7; 脊椎骨: 26 - 27. This species is distinguished from its congeners by the following set of characters: longitudinal row scales 33-36; predorsal scales 20-26; snout length 9.4-11.5% of SL; upper jaw length 13.4-16.0% of SL; caudal fin length 27.3-34.6% of SL; opercular scales with ctenii; infraorbital neuromast rows from eye is usually six. Colouration: with conspicuous silver or white spots on head, body, and dorsal and caudal fins; while juveniles have two inverted triangular bands
on body; anterior of body with silver spots; caudal fin base no bright markings (Ref. 133165).
Body shape (shape guide): fusiform / normal; Cross section: oval.
All specimens collected (from Ryukyu Archipelago) were caught in mangrove estuaries (Rhizophoraceae species dominant), in mainstream areas, channels, and pools near river mouths (salinity 14-30 ppt, 3 sites). It was observed to be particularly abundant on Ishigaki and Iriomote islands (southern Ryukyu Archipelago), but relatively rare northward from Okinawa Island. Juveniles were usually in brackish pools with leaf litter on the muddy bottom. On Iriomote and Ishigaki islands, this species was usually observed with other gobioid species, including Acentrogobius janthinopterus, Bostrychus sinensis, Eleotris melanosoma and a Mugilogobius sp. (Ref. 133165).
