The column sometimes has a thin cuticle of hardened mucous. Size up to 30mm across base and 60mm high but usually much less. Coloration similar to, but usually brighter than Sagartiogeton undatus, usually with orange on the disc and more sharply defined pattern with dark markings at base of tentacles.

Habitat: Exclusively sublittoral. Usually on shells, worm tubes, or other organic substrates but also occasionally on stones or bedrock. Usually in small groups. Sometimes buried in mud or sand.
