Do saki monkeys possess a grooming claw?

[摘要] The presence of a grooming claw on the second toe is a characteristic of Strepsirrhini and tarsiers. There is also some evidence for the presence of a grooming claw in Platyrrhini. Here we report qualitative findings from different species of saki monkeys, genus Pithecia , on the presence of modified nails on the second toe. These observations suggest that a grooming claw or a grooming claw-like nail occurs in different Pithecia species, but that it does not consistently occur in all individuals.
