San Diego Zooさんのインスタグラム写真 - (San Diego ZooInstagram)「Swipe to boop Mary's snoot ➡️ 🐘 and keep reading to learn more about this unique appendage. An elephant’s trunk is both an upper lip and a nose. There are no bones or cartilage in the trunk, but there's other junk... like muscles! There are 8 major muscles on each side of the trunk and 150,000 muscle fascicles (portions of muscles) for the entire trunk. An 🐘’s trunk is so strong it can push down trees and so agile that it can pick up a single piece of straw. #SnootBoop #Elefun #TrunkJunk #SanDiegoZoo」9月4日 8時03分
