Final answer:
Tarsiers are fascinating to our taxonomy because of their unique characteristics, such as being the smallest known primates, having large eyes and a 360-degree head rotation, and being the only primate carnivore.
Step-by-step explanation:
The tarsier is fascinating to our taxonomy because it has both prosimian and anthropoid characteristics, making it difficult to classify. It is currently classified within its own classification under the haplorrhines. One of the characteristics shared by tarsiers and other haplorrhines is the inability to manufacture their own Vitamin C. Tarsiers are the smallest known primates and have unique features such as large eyes, a 360-degree head rotation, and being the only primate carnivore.
