Clathrinidae is a family of calcareous sponges in the order Clathrinida.
This family of sponges has bodies mainly composed of interconnected tubes. The supporting structure, or skeleton, is lined with three-rayed (triactine) spicules, sometimes accompanied by tripod-shaped, four-rayed (tetractine), and two-rayed (diactine) spicules. A continuous choanoderm lines the internal cavities. Water enters through pores in the body wall formed by specialized cells called porocytes.[2]
Young Clathrinidae begin as simple tubes. As they grow, the tubes divide lengthwise, produce buds, and come together to form a larger network called a cormus. The cormus has no shared outer covering and no clearly separated systems of canals for incoming or outgoing water.[2]
Genus Ascilla was formerly assigned to this family, but was reclassified as Neoernsta gracilis in 2023.[3]
