Facetotecta is a poorly known subclass of thecostracan crustaceans.^[1] The adult forms have never been recognised, and the group is known only from its larvae, the "y-nauplius" and "y-cyprid" larvae.^[2] They are mostly found in the north Atlantic Ocean, neritic waters around Japan,^[3] and the Mediterranean Basin, where they also survive in brackish water.^[4]
