In the past few years, I have handled or petted several nice species including tuataras, Galapagos land iguanas, aye-ayes, clouded leopards, echidnas, koalas, wombats, Naultinus geckos, tree kangaroos, great blue turacos, deep sea isopods, dugong, giant flying squirrels, fishing cats, alligators, pangolins, etc.
One of the funniest things I did was photographing living Arctic fishes behind the scenes in an aquarium. Outside it was 20+ degrees Celsius, but these fish were kept in a cold box that was in an old, unstable building. So there I was, with my ski jacket, gloves and construction helmet photographing fish in a walk-in freezer.
