Doctor Who Concordance Wiki

The Raxacoricofallapatorians were a species of calcium-based
life forms that inhabited the planet Raxacoricofallapatorius in the Isop Galaxy. (SJA: Alien Files: "Episode 6")


Raxacoricofallapatorians like the Slitheen family were hunters, humanoid in form and over two metres in height. Their strong arms were well equipped to swim through the oceans on their home planet, while their large eyes were capable of seeing in its blizzards. (SJA: Alien Files: "Episode 6") Their bodies consisted of living calcium, which made them vulnerable to acetic acid. (DW: "World War Three")

In extreme cases of danger, a female Raxacoricofallapatorian could manufacture a poison dart within her own finger. (DW: "Boom Town")
