The '''Smittinidae''' is a family within the [bryozoa](/source/bryozoa)n order [Cheilostomatida](/source/Cheilostomatida). Colonies are encrusting on shells and rocks or upright bilaminar branches or sheets. The zooids generally have at least one [adventitious avicularia](/source/avicularium) 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](/source/ovicell), which [broods](/source/brooding_(bryozoa)) the [larva](/source/larva)e internally, is double-layered with numerous pores in the outer layer, and sits quite prominently on the frontal wall of the next zooid.
