Alopius vulpinus is a scientific name for the red fox, which is a mammal of the Canidae family. The red fox has several synonyms, including Vulpes vulpes, Reynard, and Tod. These names are used interchangeably to describe the characteristics of the animal. The Vulpes vulpes name is derived from the Latin word "vulpes," which means fox. Reynard, on the other hand, came from the French folktales of a character who was depicted as a clever and cunning fox. Tod is a word that originated from Old English and means fox. Despite having different names and origins, all these synonyms are used to refer to one animal, the red fox.
