Plural of coenenchym; the shared connecting tissue in colonial marine animals like corals that allows individual polyps to function as one organism.
From Greek 'koinos' (common) + 'enchyma' (tissue) + '-a' (plural suffix). This is the standard biological term for coral colony tissue.
Under a microscope, coenenchyma looks like a complex network of connections—each coral polyp is like a cell in a larger body, and the coenenchyma is what binds them together.
