Induction of metamorphosis of larval Phestilla sibogae by increased external potassium. Potassium was added in excess to MBL seawater as KC1. The percentage of larvae metamorphosed was scored at 24 h (•), 48 h (A), and 72 h (•) of continuous exposure. Data are averages of duplicates, with standard deviations indicated by vertical bars. The effects of excess K+ in combination with those of substratum-derived inducers or their analogs were ad
