||Sea mats, horn wrack & lace corals
| Recorded distribution in Britain and Ireland
||In the British Isles, Victorella pavida is only found in Swanpool: a brackish water lagoon near Falmouth in Cornwall.
| Habitat information
||Found in areas of low and fluctuating salinity such as estuaries and lagoons. The trembling sea mat grows in shallow water on submerged stones, plants and wood as well as artificial substrata such as concrete.
||This creature looks more like a plant than an animal. It is a colonial bryozoan that may form either diffuse branching chains or develop into dense clumps. During the peak of the growth season (summer), colonies have the appearance and texture of velvet. Individuals within a colony vary in shape and size. Attached zooids posses a roughly oval base and a cylindrical peristome (erect tube). Erect zooids may be cylindrical of slightly bulbous at the base. In dense colonies the zooids may be as short as 0.3 mm and in diffuse colonies they may reach 1 mm long.
