I may mention that I have kept snakes, including a cobra, and am therefore the less likely to be easily deceived by a bad imitation. February 19, 2018 Vision adaptations allow for hunting at night, through dense areas of forests (Welman et al, 2017).

In the presence of bird predators, individuals vocalize and disperse to hide. Tarsiers tiny, carnivorous primates are our distant cousins, according to scientists at Washington University School of Medicine in St. Louis, who sequenced and analyzed the tarsier genome. Conclusion. In other words, India and southeast Asia. 1. Accessed -Tarsiers are very sensitive to sound, and in the wild their habitat is often quite loud.
