Amphibian larvae need to be able to produce several hormones to stimulate
metamorphosis. One of the key molecules is thyroxine, basically an amino
acid with iodine. If the tadpoles have an iodine-deprived diet they won't be
able to go through metamorphosis. The easiest sources for available iodine
are iodized salt and marine kelps/algae. Just a thought...
