> Anything with tiny pores put on the sea will either be covered in life in weeks

My question with this, is that if an air bubble is formed against the surface of the material and thus the water is not touching the surface.. how does the life inside the water attach itself to the surface which it does not touch?




Marine larvae have legs with strong claws and chaetas and secrete several natural cements. They could just displace or peel the air bubble. Moreover, having tiny pores would grant a stronger grip to the hull against being washed by sea currents and cleaning hoses.


That’s assuming there’s one perfect & stable air bubble that is never broken?

If something gets into even one pore and starts displacing air, that would be enough to break equilibrium, right?
