Paracentrotus lividus

Range & Status

This species is found in hollows and crevices in the intertidal zone and in the sublittoral to about 30m depth, on stony ground and burrowing in lithamnion gravel (maerl). Once common in western Ireland, from Cork to Donegal, now depleted by commercial harvesting. Occasional in the Channel Islands, rare in south-west Scotland and very rare in Devon, Cornwall and the Isles of Scilly where there are several old records. It may persist in the extreme south-east of Cornwall where the substratum consists of limestone.
