I have a question hoping someone(s) can answer.

I have a tabpole which is different in the underside colouring then the rest. It has a silver underside. Do spotted marsh tabpoles ever have silver undersides? Its the same colour elsewhere as my spotted marsh tabpoles thou its also got none of that freckled or dappled look on it yet either.. so is plain in colour (but pretty with its silver underside).

Anyway.. interested to hear any of your marsh tabpoles have silver undersides? or is this likely to be something else thou it blends with other tabpoles I have on the other parts of its body Another kind of marsh frog??? (the two types of frogs I have, I was given from outdoor pond 10 tabpoles which were supposed to be spotted marsh (some certainly are that) and I had 2 tabpoles which I was told were "local marsh frogs" whatever those are.

Silver undersides??
