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, and lights up with brilliant bioluminescence. The team published a description of the animal, nicknamed the “mystery mollusk,” in the journal Deep-Sea Research Part I.
