University of Auckland scientists captured footage of a Maori octopus clinging to a shortfin mako shark, raising questions about marine behavior and ecosystem dynamics.

The two species generally don't come into contact with one another.

Overview

  • The interaction was documented in December 2023 in New Zealand's Hauraki Gulf and released publicly in March 2025, drawing significant attention.
  • The Maori octopus, typically a seabed dweller, was seen gripping the dorsal region of the world's fastest shark, the shortfin mako, in an unprecedented interaction.
  • The encounter lasted around 10 minutes, but researchers could not determine its outcome or the exact reason for the behavior.
  • Scientists suggest the octopus's actions may have been defensive or opportunistic, but the exact ecological dynamics remain unclear.
  • The sighting highlights the importance of marine conservation and further research to better understand and protect ocean ecosystems.
