Borojevia cerebrum is a species of calcareous sponge from the Mediterranean Sea.

As the cormus of the holotype is fragmented, it was not possible to determine its organization, or establish the presence of water-collecting tubes.

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

In the distal part, before the tip of the actine, there are sharp spines arranged in 3-4 rows.

When the centre is not raised, they are similar to large triactines, but it is still possible to recognize them by the shape of the stout conical actines.
