Primates

Tamarins ['ta-m&-r&n] and Marmosets [mär´muzet] make up the Callithricidae, the most primitive monkeys. They do not have prehensile tails and their thumbs are not opposable. They have claws on all of their digits except for their big toes, which have nails. Their size ranges from the size of rats to the size of small domestic cats. It is common for them to have twin births and the infants are usually carried on the backs of their father and only go to their mothers for nursing. Both lack the ability to change their facial expressions.
