Revillagigedo 2022 – Story
Known as the “Galápagos of Mexico” the Revillagigedo archipelago lies 500 kilometers south of Cabo San Lucas. Archipelago consists of four islands of volcanic origin: San Benedicto, Socorro, Roca Partida, and Clarion.
We were lucky and at the turn of March and April we visited 3 of them: San Benedicto, Socorro and the amazing Roaca Partida. This diving project, lasting more than three weeks, was so far the best I have ever experienced. From the first week of diving with blue sharks and sea lions near Cabo San Lucas, through amazing week of diving at Revillagigedo archipelago to the final week of diving in the Sea of Cortez with sea lions and an army of devil reys. The picture is worth a hundred words, so instead of the usual report, I only attach slightly commented photographs.

3.4. 2022 – San Benedicto: Starship Sphyrna lewini in the Benedictine Nebula / Scalloped hammerhead (Sphyrna lewini) @ San Benedicto
Vesmírná stanice Sphyrna lewini v mlhovině San Benedicto. Focení kladivounů u ostrova San Benedicto bylo bohužel nad moje fyzické možnosti a i moje sestava není svou „takeláží“ úplně vhodná na nahánění zvířátek pod 25m hloubky. Někteří z nás měli štěstí a stihli celou „školičku“ cca 15 kladivounů jen pár metrů pod hladinou. Jako opozdilci jsme za nimi již museli výrazně hlouběji. Ovšem ve chvíli, kdy začínaly prosvítat bílé ostrůvky písku na dně, začala celá scéna připomínat vesmír a těla kladivounů mimozemský vesmírný svaz. Sphyrna lewini v dokumentačním provedení, ale vlastně to jsou mé první fotky kladivouna, kde je opravdu jasně vidět, že to je kladivoun 😉 a pak je tu vzpomínka na úžasnou „vesmírnou“ atmosféru.
