10 minutes into the dive in the south point we already had seen white tips, galapagos, silvertips, hammer heads and silky sharks!

Roca Partida!
Our first day at Roca and the morning was a bit windy but with it something unexpected arrived that made us get up from our seats at breakfast time! A calf of a humpback whale came and did a full swim around the boat, it was less than 60' the Solmar V! It was kind of showing off, lifting it's head out of the water checking us out! It was slowly swimming by the boat inviting us to jump in! Then it took off heading toward the rock, with other whales jumping out of the water in the area too.
A very nice first dive took place mostly at the southern point of the Rock where Galapagos sharks, silver tips, some hammer heads and silky sharks, along with a world of fish congregated. There were also a small bait ball of fish, so a few probably 80 to 100 lbs yellow fin tunas noticed that and started to chase the bait ball at full speed not one second later Galapagos and silver tip sharks adopted a similar behavior attacking the same bait ball, we had a full view of the event happening just above us, minutes later at the spot we had a run of striped bonito, 10 minutes into the dive in the south point we already had seen white tips, galapagos, silvertips, hammer heads and silky sharks! Water temperature was 77  ̊F, vis over 100ft, current from south.
We were hoping to have the opportunity to go find whales in our surface interval but the wind picked up and made us stay on board!
We had a strong current at the rock on the second dive that turned out dive into a drift dive in the form the southern point to the north! We found white tips with lots of fish as we made our descent, at depth some galapagos and silver tips were hanging out close by, other fish like redtail trigger fish, jacks, Moorish idol, leather bass, and cottonmouth jacks were just below us. 
On our third dive we did a bit of a swim but it wasn't hard to find a neutral point to stay out of the current, all fish came back again to shallow water doing all type of formations, the sharks came back also, about 12 Galapagos and 6 silver tips among with hammer heads that were making circles in the same spot.  The north end of the rock had some excitement too with Galapagos shark and a chevron manta that hung around for a couple minutes, our safety stop was as usual surrounded by fish in a water temp of 79 ˚F, visibility well over 100ft!
