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]
