Puget Sound is home to unique underwater creatures, especially the bluntnose sixgill shark. Sightings of these prehistoric sharks increased notably from 2019 to 2024. Diving for sixgills typically occurs during the summer months at night, when they come closer to recreational depths. Photographers should prioritize safety and be ready with their camera settings, as encounters can be brief but impactful. Utilizing proper buoyancy and lighting techniques is essential in the challenging visibility conditions.
