Sura speech is a non-verbal language that suras can use to converse over short distances, even in outer space. It appears to be a form of telepathy or based on some form of EM radiation.
- While most humans cannot understand it, suras can understand human speech, making one way conversations possible.
- It may be an ability that one is born with. If it could be learned, Leny would have learned it from Shess in the 15 years she lived with him.
- According to episode 2-179, there are certain circumstances in which a human will be able to hear sura speech (but the exact circumstances aren't explained).
