متن کاملRevision of the Hawaiian Stylasteridae (Cnidaria: Hydrozoa: Athecata)
Four species of stylasterids are described from the Northwestern Hawaiian Islands (Kure to Kaua‘i) at depths of 293–583 m, including three new species: Distichopora asulcata, Stylaster griggi, and S. infundibuliferus. In addition, specimens of Distichopora anceps were observed and collected, showing it to be the most common macroinvertebrate on the northwestern slope of Laysan Island but not kn...
