Rare, deep-sea encounter: California scientists observe 'extraordinary' seven-arm octopus

  • California scientists record a rare seven-arm octopus (Haliphron atlanticus) at 700 meters depth in Monterey Bay.
  • The octopus was filmed eating a red helmet jellyfish, a bioluminescent creature that avoids sunlight.
  • The seven-arm octopus is actually eight-armed; the male hides its eighth arm for sperm transfer.
  • The octopus reaches large sizes and feeds on gelatinous prey, surprising scientists about its diet.
  • MBARI researchers conducted the observation on Nov. 6 during a Monterey Bay expedition.
  • The footage was captured by a remotely operated vehicle at about 700 meters depth.
  • This sighting marks one of only a few dozen recordings of this species by MBARI over decades.
  • Researchers note the octopus's twilight-zone habitat lies 650 to 3,000 feet below the surface.
  • MBARI’s team continues to study deep-sea cephalopods and their unusual diets.

Before megalodon, researchers say a monstrous shark ruled ancient Australian seas

  • A massive Darwin-era shark predates Megalodon and extends the timeline of giant lamniforms further back in Australia’s Cretaceous seas.
  • Vertebrae-based size estimates indicate the Darwin predator was a colossal early cardabiodontid, predating prior expectations for giant sharks in the region.
  • Researchers used fisheries data, CT scans, and mathematical models to reconstruct the predator’s size and shape, linking modern methods to ancient giants.
  • Shark vertebrae, not teeth, provide size clues, helping scientists build a clearer portrait of this long-ago giant’s dimensions.
  • The find expands the known era of giant cardabiodontids, suggesting enormous predators thrived well before later apex sharks.
  • The Darwin site records a paleocean environment where long-necked plesiosaurs shared waters with giant sharks, revealing a rich Cretaceous marine ecosystem.
  • The study’s portrait implies modern sharks rose early to top prehistoric food chains, with deep roots tracing to the Darwin mega-predator.
  • The discovery provides a framework to search for other ancient giants in similar coastal environments worldwide.
  • Vertebrae-based clues enable a more reliable size estimate, correcting overreliance on teeth for ancient shark reconstructions.
  • The new reference corroborates the emergence of mega-predators earlier than previously recognized, reinforcing the evolutionary narrative of shark globalization.
  • The integrated approach—combining vertebrae, paleoecology, and lineage context—strengthens our understanding of prehistoric marine ecosystems in northern Australia.
