The abnormal face of the torsion also has short, large, membranous ears that are almost constantly moving, especially in the bones of the long ankle (tarsals, hence the name tarsier), a small body and a round head that can be rotated 180 ated. at http://pin.primate.wisc.edu/factsheets/entry/tarsier. The second and third toes on their feet have claws instead, which they use for grooming. Because of the shy nature of tarsiers, there is often limited information about their distribution and the effects of human interactions. Based on phylogenetic research, including molecular data, tarsiers are more closely related to humans and apes then lemurs and lorises. This could lead to health problems down the road, as their bodies are not designed to digest plant-based material. Tarsier eye size, relative to body size, is the largest of any mammal and directly correlates to their nocturnal behavior (Gillian, et al. Physiological Zoology, 60: 596-600.

Study finds adorable-looking mammal with big eyes and funny fingers on the same evolutionary branch as monkeys, great apes and humans. It thrives in both old-growth and secondary forests but can also be found in low scrubby vegetation, even around villages. Searching for the Haplorrhine Heterotherm: Field and Laboratory Data of Free-Ranging Tarsiers. That bite, combined witha hiss-like vocalization,sinuous movements, and adistinctive defensive posture in which the loris raises itsarms above its head,makethe primate look remarkably like a spectacled cobra ready to strike. Are tarsiers dangerous? "The tarsier genome is a modern archive of evolutionary changes that led to humans." Having the complete tarsier genome also allowed the researchers to comprehensively study the genes that make tarsiers unique. Some live in pairs, groups of variable size, and some males may live alone. The Siau Island tarsier is regarded as critically endangered and is among the worlds 25 most endagered primates. Tarsier taxonomy is a matter of some debate; however, most biologists divide Tarsiidae into three genera (Tarsius, Cephalopachus, and Carlito [Philippine tarsiers]) and recognize 13 or more species. In the village area, tarsiers can be found around the trees and vegetation. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. at https://doi.org/10.1093/molbev/msx312.

These clades are composed evolutionarily and geographically, as some species are only found on certain islands or in particular regions. Their fingers are tipped with sticky pads and nails that help them grip when climbing and leaping, alongside their slender tail for balance. Haplorrhines are split into three groups: 1) the catarrhines, old world monkeys, apes, and humans; 2) the platyrrhines, new world (South American) monkeys, and 3) tarsiers. It will help us determine how endangered they really are so we can implement measures to better protect them..
