Silky Sharks Swimming in the Moonlight

Location: Roca Partida, Socorro/Revillagigedo Islands, Mexico

Comments: Divemaster Sten reports that their first dive was a sight! Two whale sharks. One was the size of a bus! 45 – 50 feet long and a little brother of maybe 21 feet. We also got visited by giant manta rays. It was a good start and we had the whale sharks around the rock for the rest of the day. We also saw whitetip reef sharks of course but just a few Galapagos and silvertip sharks – likely because of the relatively warm water?! A good day. At night with no moon we were surrounded by about a 50 silky sharks chasing flying fish in the floodlights of the Nautilus Explorer.
