General Biology Additional InformationThis species becomes very flat in contraction, only a few millimetres thick. It is rarely present in abundance in any one locality. Sagartiogeton undatus is often found in the company of Sagartia troglodytes or Cereus pedunculatus, where these occur buried, and in the past has been confused with both these species although easily distinguished from them by its lack of suckers. Philip Henry Gosse christened this species the Snakelocks, but this name proved popular with the more common species Anemonia viridis.
