Coralline Seaweed Powder, 25 kg

Corallina officinalis is a calcareous red seaweed which grows in the lower and mid-littoral zones on rocky shores.It is primarily found growing around the rims of tide pools, but can be found in shallow crevices anywhere on the rocky shore that are regularly refreshed with sea water. It predominantly grows on the lower shore, especially where fucoid algae are absent, but is also found further up shore on exposed coasts.It forms calcium carbonate deposits within its cells which serve to strengthen the thallus. These white deposits cause the seaweed to appear pink in colour, with white patches where the calcium carbonate is particularly concentrated, such as at the growing tips. The calcium carbonate makes it unpalatable to most rocky shore grazers.C. officinalis is common, to be found on solid rock around Great Britain, Ireland and Isle of Man. Also recorded from the North Atlantic coast, from northern Norway to Morocco, and intermittently from Greenland to Argentina. Corallina is also found in USA, Argentina and elsewhere including some parts of Japan, China, Australia and New Zealand.
