Common name: Glycerin Sponges

Niphatidae, commonly known as Glycerin Sponges, are a family of marine demosponges found in a variety of reef environments. They are characterized by their soft, often brightly colored bodies and a unique chemical composition that includes glycerol-based compounds, which is where their common name derives from. These sponges are filter feeders and play a crucial role in the nutrient cycles of reef ecosystems. In the aquarium, they can be fascinating additions, providing both aesthetic appeal and biological filtration. However, they require stable water conditions and careful handling to thrive.
