Silky Sharks Of The Socorro Islands

The silky shark (Carcharhinus falciformis) gets its name from the smooth texture and silky look of its skin especially when it is young. These sharks can grow to 2.5 meters (8 feet) in length and are very abundant in the Revillagigedo Archipelago. Generally referred to as the Socorro Islands, these volcanic islands lie approximately 390 kilometers (240 miles) off the coast of Cabo San Lucas in Mexico.silky2silky4

Although we encountered scalloped hammerheads, tigers, Galapagos, whitetip reef, and silvertip sharks the most numerous were the silky sharks. At dusk, as the sun was setting, a few of us slipped into the water behind the boat in an attempt to photograph these sharks with the sun’s rays penetrating behind them to give a visually stunning look. Thank you to Andy Murch of Big Fish Expeditions for showing us this technique as we are relatively new to underwater photography.

Giant Mantas of San Benedicto Island

The focus of our trip was to photograph the giant mantas (Manta birostris) at San Benedicto Island in the Revillagigedo Archipelago. These are the largest mantas in the world and can be more than 20 feet (6 meters) across and weigh up to 3,500 pounds (1600 kilograms). The dive site called “the Boiler” is a cleaning station for these mantas where fish remove parasites from their bodies. Consequently, this site provides the best opportunities to see and photograph these gentle giants.

The Revillagigedo Archipelago lies approximately 390 kilometers (240 miles) off the coast of Cabo San Lucas in Mexico. These Pacific islands are more commonly referred to as the Socorro Islands. Aboard the Southern Sport, we dove 3 of the 4 islands (Roca Partida, San Benedicto, and Socorro).

“The Boiler” has the best encounters in the Revillagigedo Archipelago, Mexico.

A color variant from the more common black and white manta is an all black or nearly all black manta. It is not a different species of Manta birostris. However, it is exciting when one showed up as it looks so different.

San Benedicto is the island for the giant mantas. They are used to divers and show no fear of people. They swim It seems a bit surreal, even a few weeks after our encounter with them, to have had huge mantas swim within a few meters of us.
