Several team members conducted a sampling in Villefranche-sur-Mer (France) at the Marine Station (IMEV). The objective was to collect symbiotic organisms (Acantharia, dinoflagellates) at different depths for microscopy and genomics analyses.

We thank the marine crew of the station (Cyril) and the EMBRC France for the welcome (Julien Lopez Pardo).

This fieldwork was supported by our ERC consolidator grant SymbiOCEAN.
