In mid July 2018, the common marmoset bred in Okayama University gave birth to a triplet. It is very difficult to raise three infants. We selected the most heaviest one of her siblings, and we call her “POCKE”. We brought her up on the bottle for 80 days from the birth instead of her own mother. After 81 days, she finaly weand. Now she has become attached to human, but we hope that she gets back to their original community, as a “common” marmoset.
