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)「Hip hip hooray, it’s National Hippo Day! Did you know? Hippos (Hippopotamus amphibious) are one of the largest living land animals. When born, calves can weigh nearly 100 pounds (45 kilograms)—and full-grown adults can reach weights of up to 7,055 pounds (3,200 kilograms)! These large herbivores inhabit parts of eastern and southern Africa, where they prefer to live along rivers and lakes. A couple of other impressive stats about hippos? They can hold their breath underwater for as long as five minutes, and they have one of the strongest bites in the animal kingdom! 🦛 Photo: Matt Biddulph, CC BY-SA 2.0, flickr」2月16日 9時44分
