Squamae

In some rodents, squamae are small tubercles resembling scales on the sole of the hindfeet.[1] Among oryzomyine rodents, their development is variable; most have well-developed squamae, but in others they are indistinct or entirely absent.[2] Delomys sublineatus and Peromyscus maniculatus also have squamae.[3]
