40x Plan Fluor. DIC. Sampled in Bay of Santander. May, 20th 2017.

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