Alvega Earthworm

The Alvega Earthworm is a humongous subterranean worm-like species native to the planet Alvega. It is strong enough to destroy a Dalek saucer ship by constriction.

History
A member of this species was sent by the Amaryll's Controller to attack the Dalek forces that were invading their planet. When the Daleks blew up Alvega, it is likely that this species was instantly rendered extinct.
