As with other members
of Order Cyclostomata, the zooecia
are at least partly calcified and have simple openings, not closed by a
constriction nor by an operculum. Lichenopora
verrucaria forms a spreading, more or less disk-shaped,
colony which does not grow by stolons.
The colony is composed of tubes (zooecia)
cemented together. Most of the tubes are scattered rather
than in rows radiating from the
original growth center. The ends of the calcified tubes can
seen but do not have sharp points. The tubes are
free of the surrounding matrix for much of their length.
verrucaria (Fabricius, 1780)
Phylum Bryozoa (Ectoprocta)
(tentatively identified) is the central, whitest bryozoan colony to the
right in the aperture of this moon
snail. The colony above it is Cauloramphus spiniferum
and the larger colony to the right is tentatively Lichenopora novae-zelandiae.

novo-zelandiae has tubes many of in regular rows
and adhered to one another out to their tips.
