Sometimes referred to as the cotton eared marmoset, their ‘tufts’ only appear as they get older and give them a very distinctive look.
Marmosets are very expressive. They have a number of different facial expressions and noises that they use in order to show what they’re thinking and how they’re feeling. If they feel angry or threatened they will frown, and if they’re scared they’ll flatten their ‘tufts’ against their head.
They’re very busy little creatures too. Although they never travel far they are active for most of the day. They start around thirty minutes after sunrise and don’t stop until roughly half an hour before sunset.
The leaders of a group of marmosets tend to be the breeding male and female, with their offspring the next in line. For the rest of the group, social ranking is decided through age.
There are lots of them and they’re not currently threatened although roughly 80% of their habitat has been cleared since records began. They’re also popular in the pet trade. Conservation efforts are in place to try to reduce the damage done to their natural habitat or homes.
