...alamanders, like all other salamanders, apparently went through a larval stage in fresh water, where the eggs are laid, before losing their gills and swimming tails and emerging onto land. Salamanders that evolved to live totally out of the water, however, lost the larval stage, emerging from the egg as a...Protein is key for digestive function of the pancreas
