Scruparia Oken, 1815

Type species: Sertularia chelata Linnaeus, 1758

Description: Colony composed of chains of zooids, either adnate or rising from the substrate, and branching from the frontal or lateral surface of zooids. Zooids are smooth, imperforate and thinly calcified, expanding from a thin proximal tube to a distal part which includes an oval frontal membrane. Avicularia absent. Brood chambers are distinct bivalved chambers, terminal to the distinctive maternal zooids, which are in turn budded frontally from an ordinary zooid. Several embryos may develop simultaneously within the brood chamber. (partly from Hayward & Ryland, 1998)

Most records of Scruparia are from shallow-water or midshelf, but it can occur at greater depths.
