Latrunculia biformis, the mud-clump sponge, is a widespread deep sea demosponge from the southern hemisphere.
Description[edit]
This tough and firm sponge is chocolate brown or olive green in colour and grows up to 90 millimetres (3.5 inches) in length and 80 millimetres (3.1 inches) in width.[2][3] They are semi-spherical or ovoid in shape, with the surface covered in conical, volcano-shaped oscules and flattened disk-like projections.[2]
Spicules[edit]
- Megascleres: Anisostyles that are smooth and straight or curved. The apical extremity is needle-like.[4]
- Microscleres: Aciculodiscorhabds are very similar to anisodiscorhabds, only differing in having a well developed spined apical projection.[4]
Distribution and habitat[edit]
This species is widely distributed across the southern hemisphere. It is a deep sea sponge and has been found at a depth of 18–1,080 m (59–3,543 ft). It is known from the coasts of southwest Africa, Río de la Plata in South America, and the Antarctic and Subantarctic regions.[2]
Biologically important compounds[edit]
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. These include several discorhabdins with anti-cancer properties.[3] Additionally, an extracted tridiscorhabdin has been shown to exhibit highly cytotoxic activity against human colon cancer cells.[5] Extracted lipids have also been shown to have strong antioxidative properties.[6]
