The occurrence of active excurrent chimneys has been observed in Smittoidea reticulata, Parasmittina trispinosa and Membranipora membranacea . In M. membranacea the chimney groups are formed by large zooids which alternate in position with smaller zooids. The patterning of 'tower cell' kenozooids, which are developed later in ontogeny, is very similar, and it is inferred that they are derived from active chimney groups, and function as passive chimneys.
