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.
