Eight species of woodrats (genus Neotoma) occur in North America. Locally known as pack rats or trade rats, these rodents are about the size of the common Norway rat. They are distinguishable from Norway rats by their hairy rather than scaly tail, soft, fine fur, and large ears. They usually have light-colored feet and bellies.
The Key Largo woodrat (Neotoma floridana smalli) was federally listed as endangered in 1991.
