Song of the Ocean and The Tale of the Ocean were different translated names for the same book. They were all science fiction novels by the British author, Asimoff, about a fantasy world made up of different species of humans, in which there was a complex relationship between humans and marine creatures, extraterrestrial creatures, and other mysterious creatures. Although the two names are not directly related in the story itself, they are different translated names of the book.
