Common name: Stellate Sponge

General information

The Stellate Sponge, Jaspis stellifera, is a fascinating marine sponge known for its star-like appearance. This species is part of the Demospongiae class, the largest class within the phylum Porifera. Sponges like Jaspis stellifera are filter feeders, playing a crucial role in the marine ecosystem by filtering water and removing bacteria and organic matter.

Care

In the aquarium, Jaspis stellifera requires a well-established system with stable water conditions. It thrives in moderate to strong water flow, which facilitates its filter-feeding habits. Hobbyists should ensure that the water is rich in dissolved organic matter and that the sponge is not exposed to air, as this can be fatal.

Reproduction

Sponges can reproduce both sexually and asexually. In sexual reproduction, sponges release sperm into the water column, which is then taken in by other sponges for fertilization. Asexually, sponges can regenerate from fragments, a process known as budding.

Symbiosis

While Jaspis stellifera does not have notable symbiotic relationships like those seen in clownfish and anemones, it does host a variety of microorganisms within its structure. These microorganisms can include bacteria, archaea, and single-celled algae, which contribute to the sponge's nutrition and health.

Habitat

Jaspis stellifera is found in a range of marine environments, from shallow reefs to deeper waters. They are often attached to hard substrates where they can maximize water flow for feeding.
