About Me

I was born with three siblings, too many babies for a marmoset mom to handle.  We were all rejected by our mom who ate our tails off and was not interested in being a mom to us. Our human took us away from our mom and bottle fed us until a safe forever home could be found. 
I have only half a tail left.  A marmosets tail is used for balance which means in the wild I would be disabled and likely not survive. 
Since marmosets are from Brazil, the Sanctuary has named me Semi.  Its a Brazilian word to help identify me by the length of my tail, the only way they can quickly tell us apart.  Semi means half or partial since my tail is half size. 
I am the bravest of all my siblings.  I am the first to try anything out. We are all very bonded and I'm happy we are together.  Nada, my brother is my very best friend and he is always close to me.

Marmoset Facts

Marmosets are tree dwelling primates. 
Marmosets are found in the tropical forests of Brazil in South America.  
They are New World Monkeys.   
Marmosets, when full grown, are about 8 inches long, with a tail twice as long as its body. 
Marmosets, when full grown, weigh 8-12 ounces.  
In the wild, they live in mixed sex groups of up to 13 individuals.  
Only the head male and female produce offspring.  Their diet is fruit, veggies, gum/sap, small insects/animals.  
Marmosets can catch colds and other human illnesses easily like measles, chickenpox, chilly sores, and even HIV.  In actual fact, marmosets can contract any illness that impacts us, people. Thus, one needs to be extraordinarily cautious to keep away from cross-contamination.  Some of our human common illnesses can be a death sentence for a marmoset.  
The common marmoset remains an abundant species and is not currently threatened, but their habitat has been degraded at a fast rate.  
Marmosets are captured and traded as pets. Though (sadly) popular as pets, they become difficult to control as they get older and are thus abandoned or killed. 
Common marmosets are used for medical experiments. They are used as such in Europe more so than in the United States, and are the most common nonhuman primates to be experimented on.

Marmosets are wild animals and have very specific requirements that are difficult to meet in captivity. Human contact can in no way replace contact with other marmosets. 
Marmosets should not be pets or living in captivity.  If you want to see a marmoset, please do so by visiting a reputable sanctuary.
