California Researchers Discover Mysterious, Gelatinous New Sea Slug [Video]

MONTEREY — More than two decades after spotting a mysterious, gelatinous, bioluminescent creature swimming in the deep sea, California researchers this week announced that it is a new species of sea slug.

The Monterey Bay Aquarium Research Institute posted video online of the new sea slug floating gently in the depths.

“With a voluminous hooded structure at one end, a flat tail fringed with numerous finger-like projections at the other, and colorful internal organs in between, the team initially struggled to place this animal in a group,” the institute said in a statement Tuesday.
