Over the past several days, 538 pelicans, 54 boobies, five sea lions, and a turtle have been found along a 40-mile stretch of coast, reports the BBC. The animals apparently died on the beach, and not at sea, say experts. What really concerns scientist is that this area is close to the spot where hundreds of dolphins were found dead earlier this year. A spokesman for the Peruvian government said officials are "deeply worried." An investigation is continuing.
