Common name: Yellow Sponge

Scientific name: Axinella flustra Topsent, 1892

General information

The Yellow Sponge, scientifically known as Axinella flustra, is a species of marine sponge found in various reef environments. This sponge is recognized for its bright yellow coloration and branching, tree-like structure which can add a unique aesthetic to any reef aquarium. It is part of the phylum Porifera, organisms that are simple yet play a crucial role in the marine ecosystem by filtering water and providing habitat for other organisms.

Care

Axinella flustra requires a well-established aquarium with stable water conditions. It thrives in moderate to strong water flow which facilitates its filter-feeding habits. Lighting should be moderate as well, mimicking the sponge's natural habitat. It is important to note that sponges should never be exposed to air as trapped air bubbles can be fatal.

Reproduction

Reproduction in Axinella flustra typically occurs through both sexual and asexual means. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges. Asexual reproduction can occur through budding, where a part of the sponge breaks off and develops into a new individual.

Symbiosis

While Axinella flustra does not have the same type of symbiotic relationships as corals or anemones, it does provide microhabitats for a variety of small marine organisms. These include certain species of amphipods and copepods, which find refuge within the sponge's structure.

Habitat

The natural habitat of the Yellow Sponge includes reef slopes and overhangs where it can be found at various depths. It is commonly distributed in the Caribbean Sea and adjacent waters, often forming part of the complex reef biodiversity.
