In Croatia Ocenebra erinaceus in shallow water are often covered with concealing algae. The cephalic tentacles in this image seem to lack the yellow tips found on those of O. erinaceus in north-west Europe.
Mediterranean O. erinaceus are often larger, more colourful and more ornate than those in north-west Europe. The differences may be geographical variation, but it would be helpful if differing specimens could be molecularly sequenced.
