Their hearing and smell are very acute. The tips of the incisor teeth are dark chestnut in color. The pigmentation on the tip of their teeth is caused by deposition of iron in the outer pigmented teeth. It weighs in at 0.11-0.14 ounces and has an approximate total length of 2-4 inches. Their lifespan in the wild is rarely more than a year, but they can live as long as 18 or 19 months. [3]
