This beautiful dark red shiny tube worm had black horizontal stripes. It was protruding from its tube even though it was low tide. I do not know this creature by any other name than a tube worm. It was growing amongst the snails and barnacles on a large rock.
The Neotaenioglossa is an extant name. It was originally named by Haller in 1882. Ponder and Warén (1988) and Marquet (1997) assigned it to the superorder Caenogastropoda. ITIS considers the order Neotaenioglossa a synonym of Cerithioidea Férussac, 1819 .
