| Abundant | 08052011 | Croyde beach Rocky intertidal zone |
Observed at low tide. Abundant in the lower shore. Completely absent in mid to upper intertidal area. Tubes numerous but no live organisms were observed. I have never noticed this species at Croyde bay, despite being a regular visitor (and keen marine biologist), in 20 years. | Sabellaria alveolata |
