Ardilla vientre rojo

The Mexican gray squirrel was introduced to the Florida Keys in 1938 and is considered an invasive species. == Taxonomy == Sciurus aureogaster was named in 1829 by Frédéric Cuvier. It is classified as part of the subgenus Sciurus within the broader Sciurus genus of tree squirrels, alongside several other North American and Eurasian species. Due to the species' considerable variety in fur color and patterns across its range, over sixty distinct scientific names have been applied to specimens since its original naming. Consequently, while the possibility that additional subspecies might be present within the species has been raised by taxonimists such as Guy Musser, at present only two subspecies are universally recognized: S. a. aureogaster: Occurs in eastern Mexico. Typically has orange to chestnut ventral fur, small postauricular patches, and a white tail accented with black or chestnut. S. a. nigrescens: Occurs in the Pacific coast of Mexico.
