Learning to operate an appendage so maneuverable yet so unwieldy (we’re talking 100,000 distinct bundles of muscle fibers) is no mean feat for a junior pachyderm. But it’s a feat that’s essential to survival. Before too long, the tiny trunk you see here will be powerful enough to rip branches from a leadwood tree, handy enough to act as snorkel for the occasional river crossing, dexterous enough to pick up a single leaf, and so finely tuned it will allow its grown-up owner to engage in complex elephant communication. #TheJoyofElephants #megaherbivore #Okavango」5月6日 9時35分
