An issue I believed had been solved within the Nineties continues to bedevil efforts to breed frogs and toads in captivity. Tadpoles appear to rising and metamorphosing usually till the stage at which the entrance legs seem. Then the entrance legs emerge as spindly, weak limbs on which the totally metamorphosed frog can not stand or transfer about to feed. There is no such thing as a recognized treatment. I used to be closely concerned in breeding amphibians within the late Eighties and early Nineties and have now taken the chance to overview the proof base on the potential trigger or causes of this situation and the way it could also be prevented.
