Gold-spotted mudskipper
Periophthalmus chrysospilos

Family Gobiidae
updated Oct 2019

Where seen? This delightful fish with golden spots is commonly seen on many of our shores. It tends to move around in groups following the water line, often in amusing 'herds', nervously moving just out of your reach. Sometimes they move in a line, following what seems to be the leader. On all kinds of shores including rocky shores, sandy areas near mangroves and seagrasses, as well as on coral rubble areas near reefs.

Features: 6-12cm. Gaily speckled with orange spots on 'cheeks' and the underside of the body. The male raises his bright orange-and-black dorsal fin to court females and intimidate rival males. Unlike females, males have elongated spikes on the first and second spine of his colourful first dorsal fin.

The mudskipper digs a burrow on soft mud flats, spitting out balls of mud as it digs out the hole. One mudskipper was seen to spit out mud missiles at an intruder! Here's video clips of this mud-slinging.

What does it eat? It eats small crabs, prawns and insects.
