It is related to normal Tangle Weed, with the exception of their varying coloration (scarlet in Prime, and purple in Echoes) and poisonous nature. Whereas Tangle Weed is merely an inconvenience, Venom Weed is truly dangerous, depleting Samus' health if she wanders into it. It is found in the Chozo Ruins and Tallon Overworld in Metroid Prime and Torvus Bog/Dark Torvus in Metroid Prime 2: Echoes.
In Prime, the Venom Weed seems to have been a result of the Flaahgra's poison infiltrating the water sytems of the Ruins (and subsequently, Phazon), causing the otherwise-benign Tangleweed to become corrupted by the toxins.In Echoes, the Venom Weed is found living on land and underwater, while a mutant strain was found in Dark Aether, seemingly having somehow reached and adapted to the dark planet's corrosive atmosphere; scanning these two Venom Weed variants from Echoes will not download them into Samus' Logbook.
As with Tangle Weed, shooting at or near it will briefly make it retract into the ground. They emit a "sighing" sound when they retract. The Tangle Weed from Phaaze possesses the ability to damage Samus, identically to all Venom Weed strains.
