First dive of the morning (Cabo Pierce) featured Giant Mantas (lots) and dolphins (three), white tip sharks and a report (rumor?) of a Hammerhead, not seen by this blogger. Naval inspection, passed with flying colors, and then around the island to Punta Tosca. Few Mantas, schooling fish. Night dive, very mellow. Waiting now for Silky shark snorkel, then to Roca Partida tonight. Good day. Good food. Great crew.
