1. Symmetrically halvedmedian genital disks, even after transplantation into metamorphosing hosts, produced more bristles within the ventral anal plate area than would be expected from their prospective significance (Fig. 6b).

2. However, Hochstetter's frog lays its eggs in shallow ponds and has free-living tadpoles, although they do not swim far from the place of hatching, or even feed, before metamorphosing into adult frogs.
