Schematic morpho‐molecular classification of Collodaria based on ribosomal genes (18S and 28S rDNA) from Biard et al. (2015).
A. Phylogeny showing molecular clades and taxonomic families.
B. Corresponding extent of the morpho‐molecular framework and main morphological features (including the presence and type of symbionts reported).
C. Scanning electron microscopy illustrations of typical silicified structures found in the three main collodarian clades. All scale bars are 50 μm.
