Regional Impacts
| Ecological Impact | Competition | |
| Amphibalanus amphitrite, together with A. eburneus and A. improvisus, is a competitor in fouling communities in Beaufort, North Carolina. However, despite their high recruitment rate, Amphibalanus spp. were readily overgrown by other fouling organisms, except when present in very high densities (Sutherland and Karlson 1977). | ||
