While some other animals, like koalas, have ridges on their paws, these aren't considered fingerprints as they don't have the same level of complexity and individual uniqueness.
Here are some examples of primates that have fingerprints:
* Humans
* Chimpanzees
* Gorillas
* Orangutans
* Monkeys (some species)
The function of fingerprints in primates is still debated, but some theories include:
* Grip: The ridges help with grip, especially on wet or smooth surfaces.
* Sensory perception: Fingerprints may enhance tactile sensitivity.
* Identification: Each individual has unique fingerprints, aiding in identification.
