I would imagine that even an aircraft covered in Zebra muscles would still prove to be a much better candidate for recovery than one in the ocean covered in coral.
I've been diving on aircraft that were quite encrusted in large coral growths. It never appeared to me that the coral was the source of much, if any damage. Keep in mind that these aircraft were submerged in salt water where the weakening effects of corrosion are much more severe.
I would consider Zebra muscles to be a nuisance in a recovery / restoration attempt, but by no means a prohibiting factor. These aircraft should still be considered prime candidates.
With that in mind I propose we assemble a team to prove my theory.
Someone distract the Navy.
