My favourite animal changes all the time. When I was younger, I cycled through various large, majestic cats such as tigers, jaguars and snow leopards. At one point, I considered the polar bear among my favourites; another time, the hippo. But now I much prefer stranger, more obscure, more underappreciated animals. And a weird, elusive, nocturnal creature that looks almost like a walking pinecone fits that bill perfectly – the pangolin.
