A recent study warned that prolonged closure of the Strait of Hormuz could trigger a global marine invasive species "super-spreader" event.

What is the Concern?

  • Over 1,500 commercial ships remained anchored for extended periods.
  • Long anchorage promotes biofouling on ship hulls.

How Does Bioinvasion Occur?

  • Marine organisms attach to ship hulls during prolonged anchorage.
  • Ships carry these organisms across oceans when trade resumes.
  • Introduced species may establish in new coastal ecosystems.
