Bourdain in S. Carolina ... barnacles

[TheDescendedLefticleOfAramis]

This recent episode had him enjoying good size barnacles on the grill.
Are these common/familiar to this region? Are they enjoyed elsewhere in the States?
If so, are there additional regional recipes/thoughts/opinions? ...

Are these comparable to Portuguese "perceves" or Japanese "fujitsubo" in kind and preparation? ...

Yes, those are percebes, but they aren't native to South Carolina. They live in sheer rock faces in cold tidal water. They are eaten mainly in Spain, Portugal and France. The preparation is usually very simple. Just boil them for a few minutes in salted water.
