Todd has winning images in the BBC Wildlife Photographer of the Year and Nature’s Best.

Skunk Clowns and Indian Bulb Anemone. This one was high on the shots list for the documentary “To the Ends of the Earth: Oceans.” The symbiotic relationship between clowns and anemone is simply balletic. 100mm 2.8 Macro lens © Todd Gustafson

Hawksbill Sea Turtle, Maldives Islands. I love the shallow lagoons of the Maldives. I also love the body angle of this turtle as he surfaces to breathe. 8-15mm 2.8 lens © Todd Gustafson

Giant Manta, Maldives Islands. The Maldives are great for big sea creatures. Mantas were 40 feet down and since I don’t dive, I did a free dive to 35 feet to get less water between the Manta and the lens. Then I thought, “Where exactly is the surface?!?!” 8-15mm 2.8 lens © Todd Gustafson

Giant Clam, Maldives Islands. The colors are different in each clam. I especially like the green tunicates under the lower lip! 100mm 2.8 Macro lens © Todd Gustafson

Whale Shark, Maldives Islands. I went to the Maldives especially to film whale sharks so most of my output is on video. I did take time to photograph, as well. 8-15mm 2.8 lens © Todd Gustafson

Anemone Crab, Maldives Islands. What a beautiful home for this crab! I love the colors of the hard sponges that surround him. 100mm 2.8 Macro lens © Todd Gustafson

Giant Southern Stingray, Grand Cayman. As with photography on land I find it important to get eye level with the subject for the most impactful photos. Here I was trying to get space between the ray and the white sand. 8-15mm 2.8 lens © Todd Gustafson

Plate Corals, Maldives Islands. The chocolate and yellow spiral of this plate coral caught my eye. 8-15mm 2.8 lens © Todd Gustafson

Table Corals, Maldives Islands. This is the most beautiful reef I have been on. Table corals as far as you could see and a soft current to guide me through. 8-15mm 2.8 lens © Todd Gustafson

Cuttlefish, Grand Cayman. They look like space ships from an alien world. They were fun to swim with and film as they changed colors every second. 8-15mm 2.8 lens © Todd Gustafson

Starfish and Anemone, Maldives Islands. There’s something primal about the light, colors, and shape of this photo. I felt like I was peering into another world. 100mm 2.8 Macro lens © Todd Gustafson
