Caulerpa, a large genus of marine Algae belonging apparently to the Siphoneae. They occur mostly in warm seas, reach a length of several feet, varying much in form, and are a bright green. The most remarkable feature they present is that though often differentiated externally into parts resembling rhizoids or rootlets, stems, and pinnately-lobed leaves, they have no internal divisions or cell-walls, so that they must either be considered unicellular or the cell theory must be admitted to be altogether inapplicable to this and some similarly constituted groups of organisms. Caulerpa furnishes the chief food of some marine turtles.
