|---|---|
| Remarks | Intertidal (Ref. 106595) to sublittoral (Ref. 106593). Found on rocky shores (Refs. 106372, 106591, 106593, 106597). Also on grounds consisting of gravel encrusted with calcareous red algae (Ref. 106597). Herbivorous grazer (Ref. 106997). Grazes on encrusting coralline algae on rocks, on dead Posidonia oceanica leaves and their epiphytes, and on the rhizomes and roots of the seagrass when accessible (Ref. 106595). Scrapes the external part of rhizomes and consumes the roots entirely (Ref. 106997). Bioeroder since it feeds on any coralline substrate (Ref. 106598). |
