簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 5 - 7; 背的軟條 (總數) : 10 - 12; 臀棘: 1; 臀鰭軟條: 11 - 13. Can be distinguished by the following characters: body depth at anal fin origin 10.6-14.6% of SL, mean 12.7%; unique among Periophthalmus species in having a greatly reduced first dorsal fin (depressed dorsal 5.1-9.6% of SL) in both sexes, and usually with only five spines, fin widely separated from second dorsal fin origin; pelvic fins united for half their length,
distinct fraenum present, posterior tips of fins pointed to bluntly pointed, fifth ray bifurcating close to base and branching about 9 times; first dorsal fin plain blackish except for slightly paler base and narrow whitish margin; second dorsal fin translucent with broad submarginal black band and a row of black spots or blotches along fin base; no melanophores on anal
fin; pelvic fins whitish or with some fine speckling; orange spots may be present on lower side of head and body when live; second dorsal fin rays modally I,11; anal fin rays modally I,12; pectoral rays 11-13; caudal fin rays usually only with ventralmost 6-7 rays branched, dorsalmost 8-9 rays rarely branched; lateral scales 58-78; predorsal scales usually 24-25 (Ref. 76839).
Facultative air-breathing (Ref. 126274)
