FRESHWATER 7 STRIPE MUDSKIPPER (Periophthalmodon septemradiatus)

Periophthalmodon septemradiatus is a species of mudskipper found along tropical shorelines of the eastern Indian Ocean where it occurs in marine, brackish and fresh waters from India to Mekong Delta Vietnam, Indonesia. It is found along in estuaries as well as in the rivers.

This species inhabits mud banks which are covered by such vegetation as mangroves, nypah palms where the water is of very low salinity, near 0 ppt, in the upper reaches of estuaries and in small tributaries.[3] It can grow to a length of 10 centimetres (3.9 in) TL.

P. septemradiatus is the only fish known to communicate acoustically while out of water and when they are alarmed they dash towards land rather than water
