Marmosets have soft and silky hair, and many have tufts of hair or manes on either side of their faces, which are sparsely furred or naked. Marmosets are omnivores, which means they eat a variety of foods. Their diet includes insects, fruit, tree sap and other small animals.
Emotionally neglected marmosets often end up developing the habit of biting, throwing tantrums and fits. They will even pull their hair, slap and scratch themselves to gain one’s attention. Marmosets are not mean animals, they have personalities of their own, and are attention-seeking creatures.
Baby marmosets when bottle-fed are quite lovable, however, their entrance into sexual maturity makes them quite aggressive and unpredictable. They reach maturity in about 18-24 months.
