Two-dimensional lifeforms are living creatures which only exist in a two dimensional plane. According to Data, they possess length and width, but no height. They appear to live in large groups and are capable of telepathy and sharing emotions, in fact they do it to such an extent that other telepathic species, such as Betazoids, may suffer the temporary loss of their empathic abilities when standing close to a swarm of Two-dimensional Lifeforms. Their bodies are also able to exert an attraction similar to gravity in nature, which can interfere with a starship's engines.
