According to my rainforest guide and contrary to popular belief, the leaf of the giant water lily cannot hold the weight of an adult human, so I was not tempted to try and cross this flooded rainforest lagoon in the Amazon using the leaves as stepping stones. It didn't look very deep but I was already acutely aware that there were a large number of creatures lurking about both on land and underwater who would be best left undisturbed, especially as I had just seen a particularly beautiful bright green vine snake nearby which he had assured me was safe.......more or less.
