Axial Furrow

The term axial furrow is used to describe the depression that runs along the centre of elongate members of the Fungiidae (e.g. Ctenactis, p. 24 of the Coral Finder).  This depression holds the polyp mouth or in some instances more than one mouth, and looks a bit like the centre parting of someone’s hair!

Some elongate solitary corals have an axial furrow e.g. the genus Fungia shown here. In some genera (e.g. Ctenactis) the axial furrow may contain several mouths.
