OFI Australiaさんのインスタグラム写真 - (OFI AustraliaInstagram)「Did you know ... Orangutans have tremendous strength. Like humans, orangutans have opposable thumbs. Their big toes are also opposable which helps them to hold onto trees and hang upside-down from branches for long periods of time to retrieve fruit and eat young leaves. Fully developed adult males can weigh up to 135 kg, while adult females weigh less than half that weight. Adult male orangutans can reach a height of 1.5 metres and can have 2.4 metre arm spans. #OrangutanAwarenessWeek #oaw2023 #OAW #saveorangutans #saynotopalmoil #orangutanstrength #orangutanfacts #orangutansize」11月12日 8時28分
