The Crimson Gusherwurm split from it's ancestor, and moved to the Wright Rainforest. The largest of the Gusherwurms, the Crimson Gusherwurm depends on blood for it's food source even more than it's cousins, the Verdant and Azure Gusherwurms. Gusherwurms feed on the blood of it's victims and are capable of both feeding on living or dead creatures, although Gusherwurms prefer to hunt living prey. When a Gusherwurm feeds on a living individual it will inject a mild sedative via it's mouth. It will do this in an attempt to impair the creature allowing it more time to feed. All Gusherwurms have a similar larval stage that will feed on only Iron until it's jaws and mouth are developed enough to penetrate the skin of it's prey. Being that the Crimson Gusherwurm consumes less iron than it's ancestor or cousins, it's outer shell and 'spikes' are softer. This allows the Crimson Gusherwurm to squeeze into tighter, harder-to-reach spots on some of it's prey. The Crimson Gusherwurm is the most successful Gusherwurm.
