3.2.10 Other PMFs in the Sound of Canna
A single Arachnanthus sarsi, a burrowing sea anemone, was seen on one of the video drops
on muddy sand on the east coast of Canna (Figure 29). This is the area in which another
individual A. sarsi was found during an SNH ROV survey in 1993. This PMF is considered
to be an MPA search feature only when the species occurs in aggregations.
The white cluster anemone Parazoanthus anguicomus, was found on much of the
circalittoral rock in the sound and was common on the cliff sites surveyed by the divers
(Figure 29). It was frequently associated with the northern sea fan and sponge communities
MPA search feature.

Offshore subtidal sands and gravels is a broad habitat identified as a MPA search feature
and PMF in Scottish offshore waters (>12 nm from land). The following component biotope
of this MPA search feature was found to be widespread within the Sound of Canna in 2010:
