ナショナルジオグラフィックさんのインスタグラム動画 - (ナショナルジオグラフィックInstagram)「Video by Joel Sartore @joelsartore | Say hello to Liilu and her three-month-old baby named Marshmallow. From birth, common marmosets have a very strong cling reflex and will spend the first several weeks of life attached to mom. Marmoset mothers like Liilu often give birth to twins that can make up more than 20% of the new mother's body weight, making a tough job even more challenging. Luckily, this species practices what is known as cooperative rearing, meaning every member of the group plays a role in caring for and raising infants! Video footage taken in Omaha, NE. To see another adorable duo follow me, @joelsartore.」5月22日 0時56分
