The Devil Birds.

We were in our long journey And swimming in the river water In groups we swims through The distance somewhat long ever Our shape and body structure so suited To the expeditions and swimming in water We enjoy the swimming with the fins And likes to live till the end The river is always helpful to us The mangrove forest gives us the place To put the eggs in time for progeny A natural rule there always visible But one day there came devilish birds They can swim and hunt us in cleverness They can visible in fresh water And catch us in tactful ways and eat The birds are coming in large numbers Their beaks so sharp enough to kill us We the fishes have to fear now Anytime they attacks us in water.
