Dive in and meet some of the most stunning deep-sea animals that MBARI encountered in 2025. This year, our team spotted ultra-black fishes, sinuous siphonophores, curious crabs, spectacular sponges, and so many more dazzling denizens of the deep—all captured by ultra high-definition 4K cameras on our advanced underwater robots. Each encounter offers important insight about the ocean’s mysterious depths, a new piece of the puzzle as we work to understand our changing ocean. These fascinating finds shine a light on the remarkable diversity of life in the largest living space on Earth.
