Rossi (Rossi, 1971) also considered that Beroe cucumis Fabricium (B. ovata Esch. Bosc) occurred in the Mediterranean Sea. Cambell (Cambell, 1982) showed that Beroe cucumis Fabricium inhabited the Mediterranean Sea as well. On the basis of comparison of the morphological features B. ovata from the Black Sea with individuals named B. ovata from the Mediterranean Sea Seravin et al. (Seravin et al., 2002) concluded that Beroe cucumis Fabricius (1780) occurs in the Mediterranean Sea.
