Flustra foliacea is not listed under any importance categories.
|Researched by:||Dr Harvey Tyler-Walters and Susie Ballerstedt||Refereed by:||Dr Joanne Porter|
|Phylum||Bryozoa||Sea mats, horn wrack & lace corals|
|Recorded distribution in Britain and Ireland||Common on all rocky coasts of Britain and Ireland.|
|Habitat information||Found on coarse sediment and rocky substrate in the shallow sublittoral, where it favours current-swept rocky grounds.|
|Description||Flustra foliacea forms a stiff but flexible bushy clump 6 -10 cm high, occasionally up to 20cm high. Flustra foliacea is much divided into fronds that are usually broadly lobed, occasionally strap-like, and made up of zooids (individuals) on both sides (bilaminar). Fronds are light grey to brown in colour. Zooids are tongue shaped, 0.4 mm long and 0.2 - 0.28 mm wide. They bear 4 to 5 marginal club-like spines at the broad (distal) end of each zooid. The fronds have a distinct smell of lemons when freshly collected. Hornwrack is sometimes found washed ashore after storms.|
