Common name: Yellow tube sponge

General information

The Mediterranean Sponge, Aplysina aerophoba, is a species of sponge found in the Mediterranean Sea. It is known for its bright yellow color when alive and its characteristic network of channels and pores that allow water to flow through it. This sponge is part of the phylum Porifera, organisms that are sessile and rely on filtering water to obtain nutrients.

Care

In the aquarium, Aplysina aerophoba requires a setup that mimics its natural environment. It thrives in tanks with moderate to strong water flow, which is essential for delivering food particles and oxygen to the sponge. It is also important to maintain high water quality, as sponges are sensitive to elevated levels of nitrates and phosphates.

Reproduction

Reproduction in Aplysina aerophoba can occur both sexually and asexually. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges. Asexually, this sponge can reproduce by budding, where a part of the sponge breaks off and develops into a new individual.

Symbiosis

Aplysina aerophoba has a fascinating symbiotic relationship with microorganisms, including bacteria and cyanobacteria. These microorganisms live within the sponge's tissues and contribute to its nutrition by processing waste materials and producing additional nutrients through photosynthesis.

Habitat

This sponge is typically found in the Mediterranean Sea, attached to rocky substrates or within crevices. It can be found at various depths, often ranging from shallow waters to about 40 meters deep. The habitat of Aplysina aerophoba is characterized by clear, oligotrophic waters where it can filter feed efficiently.
