Bearded mudskipper
Scartelaos histophorus

Family Gobiidae
updated Nov 13

Where seen? This long mudskipper is often seen at Pasir Ris and Chek Jawa. Its preferred habitat is soft liquid mud where it often squirms rapidly in a snake-like manner. According 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 and air.

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 when leaping.

What does it eat? It eats tiny bottom dwelling creatures such as diatoms, ostracods, copepods and worms.
