A pair of Giant mudskippers (Periophthalmodon schlosseri) found at Sungei Buloh Wetland Reserve in September 2013.

This species is found mainly in the mangroves. As the name implies, it is one of the largest mudskipper species around. In the morning in which these pictures were taken, the tide was low. Therefore the mudflats were exposed and these came out from their burrows. These 2 didn’t seem to be aggressive towards each other although their fins were upright. I suppose they were having a courtship ritual, but frankly I am not sure.
