40x Plan Fluor / 60x Plan Fluor. DIC. Sampled in Bay of Santander. March, 29th 2017.

According to personal communication with Dr. Temereva (Professor of Invertebrate Zoology, Moscow State University, Russia), the morphological characters of these specimens of actinotroca larvae coincide with the descriptions of Actinotroca sabatieri and Actinotroca hippocrepia, which have been described as the larvae of Phoronis psammophila and Phoronis hippocrepia, but to verify the correlation of their identities a comparative analysis of sequences of DNA between larvae and adult specimens would be required.
