Tethya is a genus of sea sponges belonging to the family Tethyidae. [1] Members of this genus all have a spherical body form [ 2 ] and some are known to be able to move at speeds of between 1 and 4 mm per day.

Tethya aurantium, also known as the golf ball sponge or orange puffball sponge, is a species of sea sponge belonging to the family Tethyidae. [1] It is spherical in shape, with a warty surface, and grows to about 10 cm in diameter.

The genus Tethya, one of the most iconic groups in the phylum Porifera. includes nearly 100 valid species. Tethya shows a nearly cosmopolitan distribution, and thus this clade could help elucidate global mechanisms of

These are massive, spherical sponges with a radially symmetrical skeleton. Most are relatively small. This is probably T. norvegica, but positive identification is difficult from picture alone. The differences between T. norvegica and some of the other members in this family are microscopic. The diameter of T. norvegica does not exceed 7 cm.

Megasclere: rounded base; apex usually blunt but sometimes sharp; styli faintly tylote, no oxea nor strongyla. Microsclere: very small chiasters; larger and more massive spherasters. Chiasters are most abundant at the surface, forming a close layer, rays: 6 to 9.
