Photo of a colony of Membranipora savartii, an encrusting bryozoan.

Size (Zooecium): Length 480 µ; breadth 300 µ

Encrusting vincularian, zooecia arranged in very regular longitudinal rows. The zooecium from which bifurcation takes place, comparatively bigger than the rest. Zooecia short and wide with slightly curved and raised distal portion. Gymnocyst absent, cryptocyst thick and well calcified, with small denticles projecting from the lateral edges. A large and conspicuous proximal denticle projects into the opesium, bearing small conical spines at its edge. Opesia deep and oval divided into two lateral compartments proximally by the large proximal denticles.

Forms included under this species show great variations, especially in the presence or absence of proximal denticles, and when present, in the presence or absence of teeth at the tip of the denticles.
