Tadpoles overhead. Overall winner, Category winner: Ecology and Environmental Science. Tadpoles of many anuran species come in high numbers, but not many make it to adulthood. Here a group of common toad (Bufo bufo) tadpoles is seen from below by Bert Willaert, Belgium. It was shot with a canon G12 camera in a Recsea underwater housing and a Dyron dome port.
This Ikelite waterproof housing for Nikon cameras is the best that money can buy. It isn't cheap but it will keep your Nikon camera bone dry up to depths of several hundred meters. This is a serious piece of kit and well worth buying if you want to take your underwater photography to the next level.
