Scalloped hammerhead sharks are generally found in the deep waters off Cocos Island, Costa Rica, where the currents are often fierce and the visibility unpredictable. It can be a tough dive with a big camera. Adriana had the advantage of a sunny day and good visibility with ample natural lighting. When a school of cottonmouth jacks came into view she waited to see if a hammerhead might appear. It didn’t take long. This particular shark stayed just long enough for her to capture a full frame with the school of cottonmouths in the background, giving her the unique composition she had been searching for.
