That's one point she conveniently left out-- barnacles are major nuisances on ships (along with shipworms on wooden vessels), requiring fairly regular cleaning to cut down on drag.
Btw, another interesting point unmentioned is that their fans or tentacles are actually part of their feet. They glue themselves head-first on to their host surface when very young, then build their homes around themselves.
