Feather Caulerpa
Caulerpa sertularioides
Also known as Saw Blade Caulerpa, Green Feather Caulerpa
Plantae›Chlorophyta›Ulvophyceae›Bryopsidales›Caulerpaceae
📍 Tropical Indo-Pacific and Caribbean
Feathery, fern-like fronds on creeping runners — arguably the most attractive Caulerpa species. Works well in display refugia where its ornamental appearance is on show. Fast-growing nutrient exporter. Same caveats as other Caulerpa: harvest regularly to prevent sexual reproduction.
