🌙 Meet some of the Zoo’s most mysterious residents: our two aye-ayes, Bellatrix and Tonks! Native only to Madagascar, aye-ayes are the largest nocturnal primates and some of the rarest animals you’ll ever see. With their oversized ears and a special “tapper finger,” aye-ayes can hear insects crawling under tree bark, then chew through wood with rodent-like teeth to scoop them out. Here at the Zoo, we recreate this by hiding treats in cardboard, wood, and metal boxes for them to discover. 💡 Fun

With its scraggly fur and piercing gaze, the aye-aye—filmed here by Joel Satore—has often been considered bad luck, but these misunderstood primates could be vital for conservation. Clove trees on the east coast of Madagascar have been ravaged by leaf miner larvae—which aye-ayes happen to be very good at hunting.
