Darwin's Mudskipper
Periophthalmus darwini
Darwin's mudskipper (Periophthalmus darwini) is a relatively newly discovered mudskipper in 2004, so little is known about it. It is a brackish water ray-finned fish found in Australia along mud banks never far from mangrove trees. It is in the goby family Gobiidae. It is named after Charles Darwin because the holotype was collected in Darwin Harbour. Its greatest distinguishing characteristic from other mudskippers is its greatly reduced first dorsal fin in both sexes.

Description
The Darwin's mudskipper has a body shape and dorsally pultruding eyes similar to other mudskippers. They have a maximum length of 4.6 cm. It has 5–7 dorsal spines, 10–12 dorsal rays, 1 anal spine, and 11–13 anal rays. Its greatest distinguishing characteristic from other mudskippers is its greatly reduced first dorsal fin in both sexes. Its coloration is modally with a background color of light brown. They typically have dark brown streaks on their heads. They usually have dark brown saddles and diagonal and irregular bars.
Range & habitat
The Darwin's mudskipper is a brackish to freshwater fish. It is found in the intertidal zone, in tidal creeks, and in inlets along mud banks. They are always near mangrove trees. They often group together. They are considered less aggressive than other mudskippers.
