MBARI's spectacular deep-sea sightings from 2025—in stunning 4K

Dive in and explore some of the most stunning ultra high-definition 4K footage MBARI filmed in 2025 with our advanced underwater robots. This year, our team spotted ultra-black fishes, sinuous siphonophores, curious crabs, spectacular sponges, and so many more dazzling denizens of the deep. These fascinating finds underscore the remarkable diversity of life in the largest living space on Earth. 2025 marked the beginning of several significant chapters in MBARI’s work, including a new President and CEO, a new flagship research vessel, a new robotic technology lab, and many exciting innovations that are helping us advance marine science and engineering to better understand our changing ocean. Our work is revealing important insights about ocean health. We hope that the data we collect and share will help guide resource managers and policymakers in their decision-making about the ocean. Our observations of life in the deep contain a trove of important information about ocean health, but more importantly, help connect audiences with our deep-sea neighbors and inspire the next generation of ocean explorers. Together, we can find ways to safeguard the future health of marine ecosystems. We invite everyone to join us on a journey of exploration, science, and stewardship.
