A roughly spherical sponge rarely more than 30 cm across. Its tissue is bright yellow, with ’golf ball’ like depressions. However, its surface may have a covering with fine algae and sediments, concealing much of its colour and surface.
There are two species, whose appearance is very similar. C. alloclada has a clean skin (and is sometimes called the Mango Sponge), while C. kuekenthali is rougher, with the pits commonly full of sand. In some intermediate forms only a single difference in spicules can help distinguish the species.
