March 26, 2018 (Groves and Shekelle, 2010; Zijlstra, et al., 2013). Since these animals have a highly restricted habitat, any changes to the same due to human interference can be highly dangerous. Some tarsier species enact mating rituals of "duetting", or mating calls that entail one party chattering out and another responding with a similar chatter. T. bancanus, T. dentatus, and T. tarsier are considered vulnerable. The tarsier genes that display unique alterations can give us a clue into human diseases involving the same genes, Warren said.

Tarsier Diet. Since, for example, the tarsiers eyes and ankle bones differ so much from those of other primates, the genes associated with eye or bone growth and development are likely to differ as well. They are nocturnal animals, meaning that they are active at night and sleep during the day. 2017. Advertising Notice These little creatures aren't harmful to humans. With the dagger-like teeth of lemurs and lorises and the eye structures of monkeys, apes, and humans, tarsiers appear to be caught between the two distinct primate lineages. animals that live only on an island or set of islands.
