Image title | Knowing there is something to fotograph but not being able to find it sort of frustrating, especially when underwater and being limited by an annoying but finite thing as an air supply.
Try imagining an area as large as a couple of football fields of underwater seagrass and an underwater visibility of about 20 meters/60 feet and you'll understand it's not easy to find a specific living animal, even it has the size of about two human beings. The "thing" I am talking about is "Dennis", the famous resident seacow (or Dugong, it's one of the three members of the Manatee family) of the Abu Dabbab bay near Port Ghalib in the Marsa Alam region of Egypt. Seeing these pictures you've probably guessed we found it but it took us two full-hour dives to actually spot it. Sure, we did come across plenty of huge and approacheable Turtles and a couple of large Stingrays but imagine being a the last stage of your dive (it's that limited air supply) and spotting an enormous dustcloud underwater, the number one Dugong signature... but no Dennis to match it. Turned out it was right above us and while we were getting highly frustrated not seeing it, he was just getting a breath of fresh air. Our paths finally crossed when we decided to go up and finish the dive while he was going down to continue vacuuming the seafloor. We squeezed a few last minutes at our ample air supply... enjoy the results! Photo: Rutger Geerling | Fotograferen.net |
