Anemone changelings were a species on Earth which could imitate other lifeforms and were telepathic in nature. They existed under the ocean, where they were able to possess and replace a sailor by the name of Michael Newman, who had great psychic abilities. They sensed the great power of the TARDIS, and forced it to land in London, where Michael had been heading to live with his wife and her uncle. (AUDIO: An Ordinary Life)
