We were a the stream searching for crayfish over turning rock after rock. All of a sudden there one was and it was different from all the others we had seen together ever. It flicked and swam away. We moved rocks looking for when all of a sudden I realized it was climbing the waterfall behind the water. It reached the top and a loose rock slammed right into him. He released and flicked backwards to disappear once again. Leo and I. #barbados #eastcoast #stream #crayfish
