Reaching around 9 cm, this
small mudskipper inhabits back mangrove, tidal mudflats and mixed sandy and
rocky beaches. On quiet beaches, it appears to be mainly active at the
narrow interface between gently lapping waves and beach sediments.
The species is identified
by the thin, pale vertical lines along each flank, though in some specimens
this may be absent. Another identifying feature are the dorsal fins which
are banded in orange, black and creamy white.
The dorsal surface is
patterned with alternating dark and light saddles, and the snout and cheeks are
patterned with numerous pale spots.
The Silver-lined Mudskipper is wide-ranging, and occurs throughout the Indian Ocean,
Southeast Asia and the western Pacific Ocean.
