Creature Lives Lyrics

Cover art for Creature Lives lyrics by Mastodon

I'd say it's about the shunning of an individual ("the creature) by the group "them," as they refer to him/her as the creature.

Further when the person speaking in the song tries to help the creature back up and speak to the group, they tell him that he too belongs in the swamp with the creature.

As for the ending "the creature lives," I think this would be saying that while the group call the person shunned the creature, it's actually the group that is a "Creature" - abandoning individualism for the collective mentality, dismissing and excluding others
