The species is named after the presence of tetrapods, the only Clathrinid sponge known to possess such spicules.

Cells with granules could not be found because of the state of preservation of the type specimen.

The skeleton comprises equiangular and equiradiate triactines and tetractines on the tubes’ interior, and tripods and tetrapods on the exterior delimiting the cormus.

The apical actine of the tetractines is shorter than the facial ones, conical, sharp and straight.

Tetrapods are similar to tripods in that they also possess stout actines and a raised centre.
