Halimeda

Halimeda (Caulerpaceae) is a calcified green alga (class Bryopsidophyceae) that is widespread today and important as a structural component of many Cretaceous – recent reefs. The thallus of Halimeda is constructed entirely of branching segments that are matted together to form a plant body, which in some species may reach over a meter in length. The plant may be regarded as one giant, multinucleated cell.
