I wont say that there arent mermaids in the ocean.. but why not? it might b tht they are scared to come up into the air. Like other fishes which are scared for the sharks, mermaids might have the fear to show their selves to us. Mayb they might even b scared of air.... what do u think? Theres a place known as the Bermuder Traingle... who knos, mayb they are inside that misterious place.
