A team of researchers at the Monterey Bay Aquarium Research Institute (MBARI) has discovered a glowing “mystery mollusk” within the ocean's midnight zone.
A new species of mollusk, Bathydevius, has been discovered in the ocean's midnight zone. Unlike typical sea slugs, this bioluminescent species has a paddle-like tail, a large gelatinous hood, and swims in the deep ocean. It moves by flexing its body or drifting in currents and is hermaphroditic, possessing both male and female reproductive organs.
