A snorkeler documented several rare marine sightings during a 14-day trip in June 2010 to Playa Esmeralda in front of Paradisus Rio de Oro, including very shy fish that were difficult to photograph, a nest of lobsters in the reef including some over 2 pounds, a zebra lionfish that is not normally found in the Caribbean but was seen coming out every morning for food, and another lionfish over one foot long known for its poisonous spines.
