Wolfweed

From Tardis Wiki, the free Doctor Who reference

The Wolfweed were domesticated mobile plants native to Chloris.

Biology

Wolfweed were round, green plants covered in vines and leaves. They moved by rolling, but could also jump to reach their prey. Wolfweed captured their prey by smothering them in packs and wrapping them in a grey, web-like substance. They had an animal-like mentality and hunted down their prey. (DW: The Creature from the Pit)

History

Lady Adrasta had several Wolfweeds specially grown in nurseries for tracking and attacking purposes. They were kept in order by the Huntsman who commanded them with a whip. (DW: The Creature from the Pit)
