green seaweed Caulerpa serrulata* Family Caulerpaceae updated Oct 2016 Where seen? This coiled, serrated seaweed is sometimes seen on some of our shores, growing in small clumps on coral rubble. Features: 4-6cm long, but often tightly coiled and thus shorter. The central 'stem' is strap-like, flat but thick. The 'stem' has serrated edges of blunt spikes. In some, the 'stem' is tightly coiled. These spiky strap-like structures emerge along the length of a horizontal 'stem' that creeps over hard surfaces or just under the sand. Usually bluish- or greyish-green. Sometimes confused with similar green seaweeds. Here's more on how to tell apart some green seaweeds. Human uses: This seaweed is reported to be edible and used in medicines as an antibacterial and antifungal agent as well as to lower blood pressure. |
