Species Account:
Bornella anguilla is considered to be uncommon on Okinawa as I have collected a total of seven individuals over a period of more than twenty years of diving here. I have photographed three others of which specimens were not collected. Perhaps an
additional half a dozen others have been seen, primarily in water deeper than 55m, but were neither photographed nor collected.
