A single Tethys fimbria was collected swimming at the surface of the Bay of Villefranche over deep water and brought into a large holding tank in the laboratory. After a couple of days, it laid this 14 cm long pink, spiral string of egg capsules, attached to the cement wall of the holding tank at just one end by a mucous strand. A second egg mass was not attached at all. Each capsule contained 15-20 eggs; the embryos hatched in about 10-11 days.
