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)「What amphibian secretes its own “sunblock” and walks instead of hops? Found in South America’s Chaco forest, the waxy monkey tree frog (Phyllomedusa sauvagii) lives in trees, where it spends much of its time resting on branches, soaking up the hot Sun. To protect itself from drying out, it secretes a waxy substance that acts like a self-made sunscreen. Flexible hind-legs help this frog spread the substance on its back, ensuring its whole body is coated with a protective layer. This amphibian is also equipped with opposable thumbs that aid it in holding onto and walking along branches in the treetop. 😏 Photo: Ianaré Sévi」8月29日 14時07分
