What is the white-ankled mouse?
The white-ankled mouse (Peromyscus pectoralis) is a species of rodent in the family Cricetidae. It is a species of the genus Peromyscus, a closely related group of New World mice often called "deermice". It is found in Mexico, and in New Mexico, Oklahoma and Texas in the United States.
The white-ankled mouse is commonly found in coexistence with the brush mouse and Texas mouse (P. boylii and P. attaweri, respectively). Often, the sympatric overlap in characteristics between these species makes it difficult to identify a specific species. The most distinguishing feature of the white-ankled mouse, and the one most used to identify the species, is the baculum of males. The tip of the white-ankled mouse's baculum is long and cartilaginous, whereas the tips of brush and Texas mice are short and rounded.
