Common name: Vase Sponge

General information

The Vase Sponge, scientifically known as Aplysina cavernicola, is a fascinating marine invertebrate that adds a touch of natural beauty to any reef aquarium. This sponge species is known for its striking vase-like shape and vibrant coloration, which can range from bright yellow to deep purple. Sponges are some of the oldest multicellular organisms on Earth, and they play a crucial role in the marine ecosystem by filtering water and providing habitat for other organisms.

Care

Caring for Aplysina cavernicola requires a well-established aquarium with stable water conditions. They thrive in moderate to strong water flow, which facilitates their filter-feeding habits. It's important to provide them with plenty of space as they can grow quite large. They do not require additional feeding, as they obtain nutrients from the water column.

Reproduction

Vase Sponges reproduce both sexually and asexually. Sexual reproduction occurs through the release of gametes into the water column, while asexual reproduction happens through budding. In the aquarium, asexual reproduction is more common, allowing the sponge to slowly increase in size or create new individuals.

Symbiosis

While Aplysina cavernicola does not have the same type of symbiotic relationships as corals or anemones with fish, they do provide microhabitats for a variety of small marine organisms. These can include tiny crustaceans and other invertebrates seeking refuge within the sponge's structure.

Habitat

In the wild, Aplysina cavernicola is typically found in the Mediterranean Sea, often in underwater caves or overhangs where it can attach to the rock substrate. They are adapted to low light conditions and can be found at various depths, often below the photic zone where sunlight penetration is minimal.
