Green Iguanas in Florida's Mangroves

The most interesting reptile seen while kayaking in the mangroves this week was a Mangrove Salt Marsh Snake (Nerodia clarkii compressicauda). Andrew and Bernhard found it and mananged to photograph it. We've seen many Green Iguanas (Iguana iguana) too. This species is not native to Florida (Central & South America) and is classed as invasive. There are some real monsters around, several feet long, but are remarkably agile in the thin branches of the canopy. I've seen them in Peru but never this close - they don't seem too bothered at human approach here. This one below was one of 25 iguanas sunning themselves at dawn around a small freshwater pond on Summerland Key.
