Animalia Paradoxa is the label given to a few species of animal, listed in Carolus Linnaeus early editions of Systema Naturae. Linné thought that these animals did not make sense. Today, such animals are usually called Cryptids. The respective section lists fantastic creatures found in medieval bestiaries as well as those reported by explorers from abroad and gives explanations to why they are excluded from Systema Naturae. According to Swedish historian Gunnar Broberg, it was to offer a natural explanation and demystify the world of superstition. "Paradoxa" was dropped from Linnaeus' classification system as of the 6th edition (1748).
