Used to diving in the Caribbean and Aegean seas I was not really used to this. In fairness it was hard to say how much life there actually was around us at any given moment, since seeing the proverbial hand in front of your face was difficult most of the time, and a lot of my visual processing power was used to try to not lose the group, who would disappear from sight after about 5-10 feet depending on the depth. Here is some sort of coral something or other though.
