Steganoporella magnilabris   (Busk,  1852) (Bryozoan)
Organism information awaits expert curation
Class: Gymnolaemata

The mandibles of Steganoporella magnilabris are commonly provided with minute lateral teeth and longer distal teeth. The opercula have very distinctive features in possessing a number of minute marginal teeth and a basal sclerite. According to Harmer (1926), this is only species in which the cryptocyst of both zooecia and avicularia joins the basal wall at a considerable distance from the distal wall. In correlation with the sharp descent of the cryptocyst, the opening of the tube lies in a transversely vertical plane, and is invisible in frontal view.
