Apomys mice weigh from 18g to 128g. The tail is longer or nearly equal the length of the head and body. The soft and thick fur of these mice is darker on the back while the front fur is paler, often nearly white with a moderate orange yellow wash. The hind feet are moderately long and narrow, have six plantar pads, and have digits 2–4 notably longer than digit 5 and the hallux. All species have two pairs of inguinal mammae.^[1]
