New Species with 'Tadpole'-Like Tentacles that Glow Discovered Off California Coast
The creature’s bioluminescent tentacles may help it lure fish, and researchers say deep-sea species still need more documentation.
- Scientists from the Monterey Bay Aquarium Research Institute , led by Steven Haddock, discovered a new species of gelatinous Erenna siphonophore during an expedition to the Channel Islands, identifying the creature roughly 6,500 feet below the surface.
- The team conducted a 10-day mission to explore deep-sea life, utilizing specialized equipment to reach depths as low as 3,700 meters following a four-year wait for a new research vessel.
- Haddock described the siphonophore's unique tentacles with glowing lures that resemble a "tadpole," noting the creature's distinctive structure is likely "adapted to attract a different kind of fish" than other documented versions.
- Bioluminescent lures allow various siphonophore species to specialize in different prey, supporting ecosystem diversity; Haddock noted these glowing animals may be more prevalent than many land-dwelling species, stating "Some of them probably outnumber us."
- MBARI continues to study how these deep-sea creatures migrate into shallower waters at night, connecting deep and shallow ecosystems, while researchers await further documentation before releasing photos of the newly discovered species.

New species with 'tadpole'-like tentacles discovered off Central Calif. coast
California’s beaches may be some of the most photographed and well-documented coastlines in the world, but just miles from the shore, scientists are still finding creatures never seen by humans.
Recently, scientists have discovered evidence of the existence of an entire community of complex organisms, such as mushrooms, worms and even late-stage, which populate the Antrim skeletal formation from...
