Blue-spotted mudskipper
Boleophthalmus boddarti

Family Gobiidae
updated Nov 13

Where seen? This pretty spotted mudskipper is sometimes seen in the back mangroves. Large adults often seen on very very soft mud. During high tide, it hides in its burrow with a bubble of air.

Features: To 22cm long, those seen about 6-8cm. Brown with 6-7 dark diagonal bars along the body. Lots of tiny blue spots on the 'cheeks', along the sides of the body and on the fins. In adult females, the first dorsal fin has elongated spines that stick out like long filaments.

What does it eat? It grazes on algae and edible bits on the surface of the mud, gathering these by moving its head rapidly from side to side. So it comically appears to be constantly saying 'No!
No! No! '.

Human uses: It is said to be eaten in some places and sometimes sold in markets.
