The 8-inch, bright pink slug has been isolated in a "sky island" for millions of years.
It belongs to a new family of sea slugs. Researchers from the MBARI dubbed it Bathydevius caudactylus and recently published their findings in the peer-reviewed journal Deep Sea Research Part I.
Small, translucent creatures — known as sea cherubs — are washing up along Oregon beaches, and more sightings are occurring in 2025 than usual, according to Seaside Aquarium.
