Figure 5 in Primary utricle structure of six Halimeda species and potential relevance for ocean acidification tolerance

Figure 5: Examples of transmission electron microscope images from which adhesion length between adjacent primary utricles (pU), defined as diffusion pathway length, were determined from six Halimeda species collected on reefs from Little Cayman Island. The diffusion pathway can be seen to physically isolate the primary inter-utricle space (pIUS) from external seawater (S). Scale bar = 10 µm.
