Dermal Protection in Mammalian Species

Typically, most animals of the class mammalia typically have relatively less durable outer dermal layers than other classes of animal, such as reptiles. It can be seen particularly in humans (Homo sapiens), where their skin is vulnerable to many external hazards. However, some mammals have developed independently to obtain much more durable dermal protection. Highlighted here specifically, will be the specimens within the families of Manidae and Dasypodidae. Respectively these families represent the animals, the pangolin and armadillo. Although of very different classes, orders, etc. these specific mammals have developed the ability to protect themselves with their own outer coverings. The

Dermal Protection in Mammalian Species

Typically, most animals of the class mammalia typically have relatively less durable outer dermal layers than other classes of animal, such as reptiles. It can be seen particularly in humans (Homo sapiens), where their skin is vulnerable to many external hazards. However, some mammals have developed independently to obtain much more durable dermal protection. Highlighted here specifically, will be the specimens within the families of Manidae and Dasypodidae. Respectively these families represent the animals, the pangolin and armadillo. Although of very different classes, orders, etc. these specific mammals have developed the ability to protect themselves with their own outer coverings. The differences in how each developed, from where, and how each family uses their adaptions will be discussed. There are approximately ten extant genera of armadillo, encapsulating 21 different extant species. All armadillos are part of the order Cingulata, which is in turn part of the superorder Xenarthra, which also includes animals such as anteaters and sloths. The most distinctive characteristic of armadillo species is the presence of a shell or carapace, which shields the body from external harm. (Vickaryous and Hall 2006) This carapace consists of different materials to assist in the protection of the animal. The initial outer layer is covered in overlapping, dark-brown, keratinized scales. (Chen et al. 2011). This keratinized layer assists
