Identifying features

  • White, yellow, orange or brownish in colour.
  • Colonies form erect fleshy masses of stout, finger-like lobes.
  • Polyps monomorphic, secondary polyps arising from solenia within the coenenchyme.
  • Sclerites abundant in surface layer of coenenchyme, forming a crust.
  • Anthocodia translucent white.
  • Cross-sections of fingers have few cavities, usually less than 12.
  • Found in areas of strong water movement, unlike Alcyonium glomeratum which prefers sheltered sites.
