“Only recently have cameras become capable of filming bioluminescence in high-resolution and in full color,” Haddock added. “MBARI is one of the only places in the world where we have taken this new technology into the deep ocean, allowing us to study the luminous behavior of deep-sea animals in their natural habitat.”

An unusual sea slug with a large hood, a tail with fingerlike projections and glowing bioluminescence has been found living off the West Coast of the US.

MBARI researchers have discovered a remarkable new species of sea slug that lives in the deep sea. Bathydevius caudactylus swims through the ocean's midnight zone with a large gelatinous hood and paddle-like tail,

A new glowing nudibranch species is the first known to swim through the ocean’s midnight zone and has unique adaptations for life in this environment. The newly discovered sea slug, Bathydevius caudactylus,

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.

A "remarkable" new sea slug nicknamed the “mystery mollusk” has been discovered swimming deep in the ocean's "midnight" zone. The species has "unique" adaptations for life in the pitch-black depths including a large gelatinous hood to trap prey,

Monterey Bay Aquarium Research Institute (MBARI) scientists have discovered a new nudibranch species. They encountered it in the depths of the Pacific Ocean, where nudibranchs had not been found before.

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,” reported The New York Times.
