When he and his Pathology Department colleagues went back and looked at the samples, De Goeij realised that choanocytes were shedding all over the place.
A higher choanocyte chamber density in LMA sponges was reported by Poppell (2013) and Schlappy (2010).
Although periods of anoxia can cause abnormal shapes of the choanocyte and its collar, our examination concurs with the earlier studies which suggest that collars are inherently variable in morphology regardless of fixative or handling.
Although the structure of the choanocyte flagellum is similar to that of larval flagellated cells, the flagellar basal apparatus is quite different.
Figure 13 shows a flagellar chamber in the course of development and one choanocyte with a minute ellipsoid granule.
As in the present study, the development of sperm from archeocytes has been documented among other sponges as well, although spermatozoids are generally thought to develop from choanocytes (Reiswig, 1983).
Flat tile-like features on the fossil's external surface, punctuated with small pores, resemble pinacocytes on modern sponges, whereas the fossil's inner surface is covered with a regular pattern of uniform pits, with many pits surrounded by collars, similar to sponge choanocytes.

Feeding in sponges has been well-documented, and with the exception of the two examples cited in the introduction, the Cladorhizidae and the Hexactinellida, particle uptake in sponges occurs at the choanocytes in the flagellated chambers or at the pinacoderm-lined incurrent canals.
