Phylum Kamptozoa is divided into four families:

  • Loxosomatidae: Solitary; mostly commensal with other marine organisms. Anus is elevated above the atrium floor with a tall anal cone. Stalk is continuous with calyx.
  • Loxokalypodidae: Solitary; stalk continuous with calyx. Lack anal cone.
  • Pedicellinidae: Colonial, forming as branching stems or as unsegmented stalks from a single stolon. Larvae undergo a complex metamorphosis after settling.
  • Barentsiidae: Colonial, with segmented stalks. Muscles found in foot and calyx, but not in the stem.



The organisms found at Heron island seem to be members of the Loxosomatidae family, because of their solitary life, fused stalk and calyx, and associative nature with bryozoans. However, the genus was unable to be identified, due to the high resemblance of organisms between the various genera: Loxocorone, Loxomespilon, Loxomitra, Loxosoma and Loxosomella. New observations of Loxosomatids usually result in the creation of new species, because of the lack of distinguishing features between species. Currently, only 6 species of Kamptozoa have been identified in the Great Barrier Reef.
