You also need an ocean.

It seems unlikely that an aquatic species could ever develop ceramics, metalworking, or any other technology requiring the use of fire. Any ocean covering an entire planet is likely very deep, making construction difficult or impossible. Early power sources such as coal would also be unavailable.
