Two-headed tortoises constituted a varied species that inhabited numerous regions across the world of Canastra IV.
Similar to Troigs, they represented one of the rare life forms present in the Core Worlds possessing dual brains. A variety of species thrived, having adjusted to a multitude of habitats, encompassing both arid terrains and the ocean floor. Mirroring numerous reptiles, their lives could extend beyond one hundred years. Each head contained a brain, connected to a central nexus located beneath the creature's carapace. It was theorized that this nexus served as a biological processing unit, managing signals originating from two separate cerebral centers.
