Gold-spotted mudskipper
Periophthalmus chrysospilos

Family Gobiidae
updated Sep 2020

Where seen? This orange spotted fish is the most commonly seen mudskipper on many of our shores. 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-yellow spots on 'cheeks' and the sides of the body. Often with many dark bars along the body too. 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.

Burrow wars: It 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!

Schools of skippers: This mudskipper is sometimes seen in small groups, moving around together along the tide line. Sometimes they move in a line, following what seems to be the leader.

What does it eat? It eats small crabs, prawns and insects. One was seen eating a tubeworm.
