This chart, and many others like it, were produced by the Park Service as an educational tool for use in classrooms, museums and universities. Popular among natural history enthusiasts, the illustrations featured on these posters were the result of intensive expeditions and surveys into the Mystery Flesh Pit. While visitors are almost certain to encounter common fauna such as the myriad of Macrobacteria subspecies, many organisms such as the Venous Shamble and Abyssal Copepod tend to evade trails and high-traffic areas, making them difficult to spot. As a practical tool, these illustrations were useful in training Wildlife Management rangers in proper firearm techniques for safely dispatching a dangerous organism. For this reason, the designers of this and other charts attempted to represent the scale of the organisms in relation to each other as accurately as possible.
