| Oryzomys are mouselike rodents with coarse but not stiff fur. They have been called rice rats, but this is misleading, because they live in many places other than rice fields, and lived in those places long before rice was introduced to the Americas. They are often found near streams or in other moist places. Some have been trapped on the ground and some in houses. Their diets can include green leaves, fruits, seeds, and insects. Some also eat crustaceans and even small fish.
Recent publications suggest that four species in the Oryzomys group are distinctly different from others and merit a new genus. Handleyomys is the genus preferred by IUCN; MSW3 and ITIS continue to use Oryzomys.
