Keltan
From Tardis Wiki, the free Doctor Who reference
The Keltan were the dominant species of Orbis.
They resembled jellyfish in their appearance. Keltans were amphibious, and had very short lifespans. They iridesced when agitated — green was the colour of fear. They slept, danced and ate and regurgitated their dead to re-fertilise the seabed of Orbis.
The Keltan were made extinct when Orbis was destroyed by a stellar manipulator. (AUDIO: Orbis)
