Trell

The Trell were ten-foot long intelligent centipedes. They were a peaceful, highly ordered race and were almost incapable of acts which might be considered illegal. Their eyesight was far superior to humans'. (AUDIO: Sisters of the Flame)

Trell were among the many alien races to be hypnotised by the Eight Legs when they attempted to use a Stellar manipulator to take control of all races in the universe. (AUDIO: Worldwide Web)

A Trell once came under attack by the Sontarans. (AUDIO: The King of Sontar)
