Scientific Details

Confused with Caulerpa vesiculifera which is lighter green in colour, has fewer larger vesicles attached to the main stem by and short rounded stems. It can also be confused with Caulerpa simpliciuscula, although the vesicles in that species don't have the distinct constriction mid way down the vesicle.
