What started as a typical dive off the coast of Mozambique, with schools of fish and pods of dolphins; took a dramatic turn when a large swarm of scalloped hammerhead sharks (Sphyrna lewini) showed up. An incredible experience this diver will not soon forget.

As of 2008, the scalloped hammerhead is on the “globally endangered” species list. Research has shown that in parts of the Atlantic Ocean, scalloped hammerhead populations have declined by over 95% in the past 30 years. Among the reasons for this drop off are over-fishing and the rise in demand for shark fins. [source]
