The Creators were an unnamed race of cetaceans who created the Cetacean Probe approximately 500,000 years before the 23rd century. Their homeworld was in the Sagittarius Arm of the Milky Way galaxy, on the opposite side of the galaxy from the United Federation of Planets. The Creators built the Probe to communicate with other cetacean species who had either reached the same level of evolution as they had, or who had the potential to do so. The crew of the USS Enterprise-A initially likened them to super-whales, but later realized that the Creators were more like super-dolphins.
