The ventral margin is slightly convex; Body length is 5. 1 ~ 5.6 times of body height and 3.5 ~ 4. 1 times of head length. The head is slightly larger and the side is flat.

Pinball fish is a small bottom fish in warm coastal waters, which has the habit of digging wells to live. Habitat in estuaries, harbors, mangroves and coastal shallow waters, as well as mudflats with silt and mud sand as the substrate, also enter fresh water; It also inhabits coastal islands, intertidal zones of ports and waters in low tide areas.

Most fish will die of suffocation due to lack of oxygen when they leave water. However, in addition to breathing through gills, mudskippers can also breathe through skin and oral mucosa to take in oxygen in the air. The mudskipper can move on land, thanks to its developed pectoral fins. The pectoral fin muscle stalk can move freely back and forth, playing the role of reptile forelimb. When the mudskipper moves on the ground, it first tramples on the ground with pectoral fins, then drags its body forward, and the steps are repeated quickly. When the pectoral fin moves forward, the pelvic fin plays a role in supporting the body. When in a tree, the ventral fin acts like a sucker, helping the body to adhere to the tree.
