I don't think anyone who's followed me here for more than a few months is gonna be surprised to see me reading Bradbury again. He's one of my favorites, and I was so thrilled to find an audio version of this story floating around on YouTube! 
Oh, man, though, this story is so sad! Imagine feeling sorry for a sea monster. If anyone could do it, it's Bradbury! 
This is one of his rare more fantasy-leaning stories, and I greatly enjoyed it! Would recommend!
