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.
