We had spent the night in the harbor at Puerto Ayora. Our anchored boat was surrounded by other tour boats. I spotted a blacktip shark in the water.
We boarded a dinghy which took us to the Charles Darwin Research Station. There, we saw many giant land tortoises, the most famous of which is Lonesome George. Somewhere between the age of 90 to 100 years old, George is the last of his species and efforts to get him to breed with other turtles have failed. When he dies, so will his species.
