To the left of the arrow it looks like a fish within a fish. I really get the impression that the waves are a combination of looks of dead fish and wave mixture. The martians are really into combining stories utilizing many props and representations that do seem unusual to us. Again, a face so many times are just the face and not the complete body But sometimes they are the complete body but parts are missing to tell the story they need to tell that is cohesive with their language in a pictograph form like the Chinese but much more 3 dimensional!
