スミソニアン博物館さんのインスタグラム写真 - (スミソニアン博物館Instagram)「When you just need to snooze for five more minutes after a holiday weekend. 💤 This is Mary Jane the baby sloth, who was born at our @smithsonianzoo in 1964. Zoo staff hand-reared Mary Jane, and named the two-toed sloth long before it was determined that the baby was a male. He’s seen snuggling at 9 months old in this @smithsonianarchives photo.」12月3日 7時08分
