Appearance

Similar in appearance to the closely-related Boleophthalmus boddarti, this species is most easily identified in the field by the fine blue spots on the front dorsal fin, and by the arrangement of hyphen-like blue spots on the second dorsal fin, which are neatly arranged in vertical and horizontal lines. Dark bands are often visible on the flanks, and in some populations the skin below the eye is pale blue.

Original combination: Gobius pectinirostris

Distribution

Northwest Pacific: China, Korean Peninsula, Japan and Taiwan. In 2009 the species was confirmed in parts of Peninsular Malaysia and Indonesia.

Habitat

Boleophthalmus pectinirostris tends to occur in open habitats in mangrove systems, such as seaward mudflats, and sparsely covered parts of the back-mangrove.
