|BRYOZOA : CHEILOSTOMATIDA : Hippoporinidae||SEA MATS|
Description: This is the largest bryozoan to be found around our coasts, growing to 40cm or more across. The colony consists of a series of brittle plates joined to each other to form a domed or hemispherical colony. Small colonies start by encrusting the rock and then growing a series of upright plates.
Habitat: This species is most common in sand-scoured habitats attached to bedrock or boulders, often surrounded by coarse gravel
Distribution: A common species in the southern part of Ireland and the British Isles, becoming more scarce in Scotland, but recorded as far north as Lewis in the Outer Hebrides.
Similar Species: No other species in the area forms large upright lamellate colonies. Smittina landsborovii is normally an encrusting species, but can grow small two-sided, convoluted plates which look like the start of a Pentapora colony.
