Latrunculia biformis, the mud-clump sponge, is a widespread deep sea demosponge from the southern hemisphere.

[2][3] They are semi-spherical or ovoid in shape, with the surface covered in conical, volcano-shaped oscules and flattened disk-like projections.

It is known from the coasts of southwest Africa, Río de la Plata in South America, and the Antarctic and Subantarctic regions.

[2] As is the case with the majority of the species in its genus, the mud-clump sponge contains chemical compounds which are of medical interest.

[3] Additionally, an extracted tridiscorhabdin has been shown to exhibit highly cytotoxic activity against human colon cancer cells.
