Those stagnant waters are breeding grounds for #biofilms and other organisms, and when those ships are eventually released, they could spread invasive species throughout Earth’s oceans.

Biofouling may result in a massive marine super-spreader event if preventative measures prove inadequate. Algae, microbes, and invertebrates (such as barnacles and mussels) spawn remarkably fast, colonizing the submerged sides and bottoms of ships after only ten days. https://www.popularmechanics.com/science/a73322161/invasive-species-strait-of-hormuz #iran #hormuz
