The genus Monanchora is defined by belonging to the family Crambeidae while lacking pseudoatrose spicules.

A typical identifying characteristic of this genus is a canal system that is swollen and has a light colored lining.

Species in this genus have simple skeletal arrangements that can develop bushes at the surface without the use of ectosomal skeletons.

In some species the microscleres may be reduced, absent or modified, resulting in problematic identification and assignment to the genus Monanchora.

Due to the wave action, the specimen experienced on the shore, the shape was irregular and its structure was impossible to determine.
