Taxonomic discussion:

Remarks.—Spongy cylindrical shells with or without protruding spines and a patagium mantle. This species is well marked by a triconvex spongy shell. Morphological characteristics are similar to those of Spongurus puella (Haeckel, 1887), but this species was synonymized with Spongurus cylindricus Haeckel, 1861b, due to morpho- logical variations (e.g. Dumitrica, 1973). A cylindrical spongy form of this species is a distinguishing character- istic from Spongurus? pylomaticus Riedel, 1958. The presence of a spongy mantle may change depending on ontogenetic differences. [Matsuzaki et al. 2015]
