Dear Bill,
I found these Polycera faeroensis in large numbers in Mont Saint-Michel Bay. They were much more numerous than the common Polycera quadrilineata.

Location: Saint-Malo, France, Atlantic coast
Site: Bizeux; Temperature: 12°C; 19 April 2003.
Upper Photo: Depth: 6m; Size: 20-25mm
Lower Photo: Depth: 7m; Size: 15-20mm

Best wishes,
Marina.

Thanks Marina,
Were Polycera quadrilineata and Polycera faeroensis together on the same bryozoans? P. quadrilineata feeds mainly on encrusting bryozoans like Membranipora sp while Picton & Morrow (1994) suggest that P. faeroensis probably feeds on arboresent or erect bryozoans such as Crisia and perhaps Bugula. The presence or absence of their food organisms could explain why one Polycera was more anbundant than the other.
Best wishes,
Bill Rudman
