Galyari

The Galyari were a species who had a deep fear of the Doctor.

Biology
The Galyari were eight feet tall. (AUDIO: Dreamtime) They had extraordinary eyesight. Because of this, they found intense colour combinations such at the Doctor's coat, painful. In the past, they had a chameleon-like ability to blend in with their surroundings. (AUDIO: The Sandman)

Technology
They stored their knowledge in the "Shushkubra", memory eggs which were grown aboard the Clutch from discarded Galyari skins. (AUDIO: The Sandman)
