アメリカ自然史博物館さんのインスタグラム写真 - (アメリカ自然史博物館Instagram)「It’s Mother’s Day and we’re celebrating with facts about some of nature’s fiercest moms. After a 15-month gestation period, giraffe (Camelopardis giraffa) mothers give birth while standing or walking. The newborns can be more than 6 feet (1.8 meters) tall, and they are able to stand up right after birth! For the first few weeks, the mother will closely guard her baby, until the pair is ready to join the herd, where the young giraffe is cared for by a group of females. Photo: Rox Bixby」5月12日 23時31分
