<< 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...
>>
It will be interesting to see how much longer these stay tadpoles but living
as close to the ocean as I do I would think that rain water from a tropical
storm would contain at least a little salt spray on the wind and contain some
iodine.
