English subtitles - Subtítulos en español - 日本語字幕 The Formiche di Grosseto ("Ants of Grosseto") are three islets included in the Tuscan archipelago (en.wikipedia.org/wiki/Formiche_di_Grosseto). The discovery in 2016 of a garden of Savalia savaglia near the largest islet gave us the opportunity to learn more, with Prof. Carlo Cerrano, the peculiarities of this species and its ecological and biological value. The dives also highlighted a particular type of interaction between the two typical chromatic varieties known for Savalia savaglia. The observation opened new hypotheses on the complex growth strategies of this species. The opportunity provided by this type of exploration underlines how technical diving is a means and not an end. A set of tools that allow to extend the duration of our excursions, to approach demanding dives making them safer and more fun or, as in our case, an example of "citizen science" that is a collaboration between technical divers and scientists.

I bought my Canon 5DII and housing in late 2009, and I can count on my fingers the number of dives I've done without it since then. In September this year I'm going to do my MOD1 rEvo course, and I'm wondering how to manage the transition to closed circuit - should I put the camera down? To put the question in perspective, I average about 100 dives a year with at least half of them in caves, and I'm OC trimix qualified. I'm used to the taskloading of navigating my way home while taking pictures, or doing multi-stage and scooter dives with one hand, while holding the camera in the other. On the other hand, I'm pretty keen on staying alive. I'm looking for the best strategy to get into camera plus rebreather dives. The options I see are: 1. Put the camera down until I have 100 (50? 200?) hours on the unit 2. Dive with the camera from the very beginning to take advantage of the instructor supervision on the course and learn to manage the whole lot together up front 3. Only combine camera with rebreather dives in the beginning where I have an instructor or experienced buddy keeping an eye on me For those who are diving rebreathers with camera in hand, how do you find it? Were you experienced in both photography and your unit before you combined the two? Second question for bonus points - is all this "No bubbles means you'll be able to kiss the fish" stuff true? Will I notice the difference in trying to get shots of skittish creatures?
