Description
The mystery mollusc (Bathydevius caudactylus) is the first nudibranch known to live in the midnight zone, an expansive environment of open water 1,000 to 4,000 meters (3,300 to 13,100 feet) below the surface, also known as the bathypelagic zone. They move through these waters by flexing their body up and down.
