↑ GalapagosPages says typical dives last only a few phút at depths of less than five metres, but Darwin reported a member of the crew submerging an iguana for an hour, and pulling it out with a rope, still alive. IUCN says that adult males can be found in marine waters, down to depths of twenty metres.
