Morphology of attached fronds and detached fragments of Codium; note variability of frond stature for attached plants (A-D), including the abundance of the epiphytic red alga Neosiphonia harveyi (D); drift fragments (E-H) also exhibit pronounced variability of stature, segmentation, and proliferation, with some being small, thick fragments (E and F), others being constricted and having incipient “winter fragmentation” (G), or relatively large and proliferous (H).
