Undeterred we boarded the dinghy to visit Santa Fe which was notable for yet another colony of sea lions but especially its own unique species of iguana. This sand-coloured, lizard-like creature has a curious symbiotic relationship with the equally unique giant cactus which grows on the island. The iguanas grow big by eating the cactus leaves that fall and the cactus growth is enhanced by the passage of its seeds through the iguana's digestive system. A good example of a local ecosystem at work.
Next up was our daily snorkel when we saw an immense shoal of fish resembling a dark grey cloud against the sandy sea floor. There must have been a thousand fish packed together in a tight circle some ten metres across. However, the highlight for the two of us was to be able to swim alongside a giant turtle. These creatures often get under a rock or swim away but we found one in shallow, clear water that seemed unbothered by our presence. We got a close look at this extraordinary beast as it swum elegantly beneath us, its green body shell shimmering in the golden sunlight.
