The Smittinidae is a family within the bryozoan order Cheilostomata. Colonies are encrusting on shells and rocks or upright bilaminar branches or sheets. The zooids generally have at least one adventitious avicularia on their frontal wall near the orifice. The frontal wall is usually covered with small pores and numerous larger pores along the margin. The ovicell, which broods the larvae internally, is double-layered with numerous pores in the outer layer, and sits quite prominently on the frontal wall of the next zooid. == Classification == *Family Smittinidae * * Genus ''Alismittina'' * * Genus ''Aspericreta'' * * Genus ''Dakariella'' * * Genus ''Dengordonia'' * * Genus ''Dittomesia'' * * Genus ''Hemismittoidea'' * * Genus ''Hippophylactella'' * * Genus ''Houzeauina'' * * Genus ''Parasmittina'' * * Genus ''Pemmatoporella'' * * Genus ''Phylactella'' * * Genus ''Phylactellina'' * * Genus ''Plagiosmittia'' * * Genus ''Platychelyna'' * * Genus ''Pleurocodonellina'' * * Genus ''Porismittina'' * * Genus ''Prenantia'' * * Genus ''Raymondcia'' * * Genus ''Rimulostoma'' * * Genus ''Schismoporella'' * * Genus ''Smittina'' * * Genus ''Smittinella'' * * Genus ''Smittoidea'' * * Genus ''Thrypticocirrus'' * * Genus ''Tracheloptyx'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Smittinidae」の詳細全文を読む スポンサード リンク
