It seems that the stricken oil tanker that fouled Charles Darwin's Galapagos island paradise cannot be moved and is set to become an artificial reef, teeming with fish and home to seals and exotic birds, the U.S. Coast Guard said on Sunday. The Ecuadorean Navy had hoped to clear the semi-submerged "Jessica" from the tiny harbor of San Cristobal island where it ran aground last week, leaking the bulk of its 240,000 gallon fuel cargo into the archipelago's pristine waters. But while the wreck may be an eyesore in the prophetically named "Shipwreck Bay," in time it will become an artificial reef and a new habitat for marine life, Coast Guard salvage chief Ed Stanton said. "Seals will start living on it, birds will begin perching on it. It has already attracted fish," Stanton said.
