Common name: Polymastia boletiformis

General information

Polymastia boletiformis, commonly known as the Puffball Sponge, is a species of marine sponge found in temperate and cold waters. It is characterized by its globular shape and numerous small, nipple-like protrusions called papillae. This sponge is non-photosynthetic and relies on filtering water to capture food particles.

Care

Puffball Sponges are filter feeders and require a constant flow of water to thrive. They are best suited for mature reef aquariums with stable water conditions. It is important to provide them with a moderate to high water flow to facilitate feeding and waste removal. They do not require additional feeding if the water contains enough dissolved organic matter.

Reproduction

Reproduction in Polymastia boletiformis is both sexual and asexual. Sexual reproduction occurs through the release of sperm into the water column, which then fertilizes eggs in other individuals. Asexual reproduction can occur through budding, where a part of the sponge breaks off and develops into a new individual.

Habitat

Polymastia boletiformis is typically found on rocky substrates in colder waters, ranging from the intertidal zone to depths of several hundred meters. They are often seen in areas with strong currents, which aids in their filter-feeding mechanism.
