Tarsiers' long tails are used for support and balance during the leap and afterword. Their long fingers give them the ability to grasp almost any surface. Tarsiers' leaping abilities are correlated with their unique hind leg structure. Their forelegs are shorter than the exceedingly long hind limbs, and in fact, their name, tarsier, means elongated ankle area. Tarsiers leap with their tail head upwards.
Tarsiers can also walk on all fours.
When doing this, they prefer to keep their tails pointed downward. When female tarsiers are ready to mate, they emit high-pitched sounds to available suitors. These sounds have a characteristic pitch. During courting, partners often chase each other while making distinctive soft sounds. But when mating begins, they maintain complete silence.
