Quotes

 * He was here, as you well know, in '35. And you'd think he was chasing finches, but he wasn't. He was actually collecting fish. And he described one of them as very "common." This was the sailfin grouper. A big fishery was run on it until the '80s. Now the fish is on the IUCN Red List. Now this story, we have heard it lots of times on Galapagos and other places, so there is nothing particular about it. But the point is, we still come to Galapagos.
