Tarquino Arevalo, captain of the Ecuadorean-registered Jessica which last week fouled the Galapagos waters with oil after running aground, told Reuters he had misjudged his entry into the prophetically named Shipwreck Bay outside the tiny harbor of San Cristobal island. "The truth is I didn't even know the rock was there. It was over-confidence on my part, I am completely to blame," the 58-year-old sailor said in an interview. "I didn't do it on purpose. This has nothing to do with my crew, it was my fault, not theirs," he added. The Galapagos are home to birds, tropical fish, sea lions and the famous Galapagos giant tortoises, but the only known damage so far to wildlife has been four dead pelicans and a dozen sea lions smeared with oil.
