From: An updated 18S rRNA phylogeny of tunicates based on mixture and secondary structure models
Predicted 18S rRNA secondary structure of a divergent aplousobranch sequence ( Diplosoma ooru ). New predicted structures unique to such divergent Aplousobranchia species (and absent in the conserved Pycnoclavella aff. detorta and Clavelina meridionalis sequences) are boxed in red. Red dotted lines indicate additional loop regions where major elongations occurred in other divergent aplousobranchs.
