The day 4, we dove at Punta Tosca for the 1st dive of the day. We had to change the site from Roca Partida to Punta Tosca because of the strong wind. It was tumbling around in the water as if we were in a washing machine right after the entry. Still we could enjoy to observe a Diamond Stingray, a Giant Electric Ray and a Galapagos Shark! Somehow they were a bit smaller. At the end, we found normal size of a Manta Ray and a Galapagos Shark! The 2nd, the 3rd and the 4th dive were held at Cabo Pearce because the condition got better! We encountered with a couple of Giant Manta Rays and a Black Manta! Hooray! They were very friendly! Especially the Black Manta even slowed down when passing above us, seemed that he was having fun with our exhaled air. Some of us saw a Tiger Shark while safety stop. The visibility was 20-25 meters. The water temperature was 25-26 deg.C. To be continued…
