An agent-based simulation of the Hydractinia colonies and their allorecognition behavior was constructed. We show evidence that the model successfully mimics the phenomenon of colony growth, fusing, rejection (both active and passive), morphological and genotypic mutation, competitive exclusion and the unexpected phenomenon of "buffering".
