When mobbing, all individuals respond to a threat with vocalizations as each repeats lunging towards and retreating from the predator (Gursky, 2002). Tarsiers are the only extant entirely carnivorous primates: they are primarily insectivorous, and catch insects by jumping at them. Socialization includes grooming each other, scent marking, vocalizing (including duetting), and playing (Gursky, 1998). With eyes twice as big as their brains, a head that can rotate 180 degrees in each direction and the ability to track prey using ultrasound, the tiny animals are formidable nocturnal hunters. That opened up the loriss habitat more and could have provided pressure to mimic a poisonous snake.
