Morphological plasticity of Caulerpa prolifera (Caulerpales, ChLorophyta) in relation to growth form in a coral reef lagoon

Caulerpa, a coenocytic marine macroalgae, is a genus characterized by having a prostrate indeterminate axis (stolon) with rhizoids and vertical axes that are potentially independent units as Caulerpa can withstand fragmentation and regenerate after a lamina or stolon are cut. This is similar to clon...
