This page represents the following TreeOfLife-200M taxonomic path.[1]
In the TreeOfLife-200M imagery associated with the class Adrianella, representative specimens are provided as fossil sponge museum-style records. The available views show curated sponge material photographed for reference.
Based on the limited image resolution/metadata available here, and the absence of extractable class-defining diagnostic statements from the provided literature extract, this page does not claim specific class-level morphological diagnoses (e.g., spicule types or internal canal architecture) from these images alone.
The TreeOfLife-200M entries supply image exemplars tied to the taxonomic label “Adrianella” at class rank. The linked museum records identify the basis of record as fossil specimen, but this workspace does not include sufficient extractable textual diagnosis to support additional, more specific claims for the class.
