to FishBase it is intertidal and found on sand and mud flats along
bay shores. Also in estuarine areas, swamps, marshy areas and on tidal
mud flats. It actively shuttles back and forth between rock pools
Features: To about 14cm long,
those seen about 7-10cm. Scales are tiny and partly embedded and thus
not visible with the naked eye. The skin on the top of the head and
on the back is full of blood vessels allowing the fish to respire
through the skin. The first dorsal fin is tall and mast-like and it
is used to display when the fish is creeping about on the ground.
This mudskipper is sometimes seen leaping 'on the spot', hurling itself
almost vertically and for a brief moment, standing on its tail! This
is believed to be part of the courtship ritual of the male mudskipper!
As it leaps, it spreads out its pectoral fins, and the second portion
of its dorsal fin. The tall, mast-like first dorsal fin is not raised
What does it eat? It eats tiny
bottom dwelling creatures such as diatoms, ostracods, copepods and
mast-like dorsal fin not raised when leaping.
