Scientists at the Monterey Bay Aquarium Research Institute identified an intriguing new deep sea species off of California. It's see-through, can glow, and nabs prey with a large hood. At one point while filming,

Scientists uncovered the "mystery mollusk," a strange glowing sea creature lurking in the ocean's midnight depths.

Formerly known as the 'mystery mollusk,' this glow-in-the-dark nudibranch is the first of its kind to be seen living in the ocean's ultra-dark midnight zone.

One of the largest known sea creatures, the size of two football fields and believed to be several centuries old, has been discovered by scientists.

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.

The new species’ sponge-dwelling habitat is “unique” and “unusual,” researchers said. Frillgobies are usually “relatively drab” fish found at shallower depths and typically “free-living on sand or hard surfaces of the reef environment.”

"Everyone in the control room let out a loud 'Oooooh!' at the same time. We were all enchanted," a researcher said.
