Cotton-Top tamarins obtain the water they need by licking leaves that are wet with rain or dew, rather than expose themselves to predation by venturing down onto the forest floor.
Sadly only 2% of Columbia’s rainforest remains. When not feeding, much time is spent in social grooming. Like other tamarins, they run their clawed digits through each other’s fur, examining it, and use their teeth, lips and tongue to pick off particles. Cotton-top tamarin groups do not represent extended families. A group may consist of a dominant pair, their young of the year and a number of unrelated subordinates.
