Periophthalmus darwini

Description

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.
