The problem with diving with blankets today in the boiler was you did not know which to choose to view and interact. It was the chevron blanket huge and very curious, but it was as 8m. As to the 12m she was one of the all black (the youngest) , as were the two other large 16m . You kept ( and I was ) one with the look and body, and when you were throwing bubbles in the stomach for what seemed like five minutes , you realized another coming the other way and wanted to do the same with the other. Everyone had several intimate moments with these giant mantas, and although the sea was moved on the surface and dive straight for the back , down and had little power and could rest easy coming and going with these wonderful things .
