A tiny goby fish searches for a meal of parasites on the snout of a grouper on the reefs off Cuba. While much of the surrounding ocean has suffered from pollution and encroachment by mankind, Cuba's protected reefs are among the few places in the world where rare aquatic life can be readily viewed and studied.
