Common name: Hairy Encrusting Sponge
General information
The Hairy Encrusting Sponge, Scopalina hispida, is a marine sponge species known for its unique texture and appearance. It is characterized by its hairy surface, which is actually an array of spicules that protrude from the sponge's body, giving it a distinctive look. This sponge is not as commonly kept as some other marine invertebrates, but it can be a fascinating addition to a reef aquarium due to its unusual form and the role it plays in the ecosystem.

Care
Scopalina hispida requires a specific set of conditions to thrive in captivity. It prefers low to moderate lighting and a moderate water flow that mimics its natural habitat. This sponge is a filter feeder, so it's essential to maintain good water quality with plenty of dissolved organic matter for it to feed on. It does not tolerate high nitrate or copper levels, and sudden changes in water conditions can be detrimental.
Reproduction
Sponges, including Scopalina hispida, have a unique reproductive strategy. They can reproduce both sexually and asexually. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges. Asexually, sponges can regenerate from fragments, a process known as budding. In the aquarium, asexual reproduction is more common, allowing the sponge to spread over rocks and surfaces.
Habitat
Scopalina hispida is typically found in the Mediterranean Sea and adjacent Atlantic coasts. It inhabits rocky substrates and often grows in shaded areas or caves, where it can avoid intense light. In the aquarium, it should be placed in areas that replicate these conditions to ensure its health and growth.
