The dermal tissue structures responsible for fingerprints are dermal papillae. They are tiny extensions of the dermis into the epidermis.
Not really. While koalas are the only known animal to have distinctive fingerprints, they can be distinguished from the fingerprints of a human. Like humans, their fingerprints comprise ridges in a variety of patterns.
The koala is the only animal with distinctive and unique fingerprints. The fingerprints are very similar to that of humans in that they are comprised of patterns, but the trained eye can distinguish them quite easily from human fingerprints.
=== Yes dogs do have fingerprints. They are on there nose, which is wierd.===
Extensions of the body cavity, located between dermal ossicles, where gas exchange occurs.
Human beings and koala bears can have fingerprints. The fingerprints of koala bears are often confused with that of human beings!

The dermal papillae are small, nipple-like protrusions of the dermis that reach into the epidermis, bringing food and oxygen to the lower layers of epidermal cells. In addition, a papilla nourishes every hair follicle. Rows of papillae protruding from the dermis into the epidermis form ridges that create patterns on the skin of the hands, feet, and body. These papillary ridges on the fingertips are responsible for fingerprints. These ridges develop sometime before birth. Not only is the pattern unique for each individual, but also it never changes except to grow larger.

Dermal ridges cause the overlying epidermis to form epidermal ridges. Collectively these ridges are called friction ridges.
