Advances in technology that enabled the discovery of a new species by California scientists may lead to a better understanding of the ocean’s depths.

It took nearly 25 years for biologists to discover that a swimming and glowing organism in the ocean’s midnight zone was actually a sea slug.

Scientists discovered a fascinating new deep sea animal they call the "mystery mollusc," and captured footage of the glowing nudibranch in its dark ocean habitat.

Scientists from the Monterey Bay Aquarium Research Institute (MBARI) have discovered a new species of nudibranch. They encountered it in the depths of the Pacific Ocean, where no nudibranchs had been found before.
