    Default Sexing American toad metamorphs

    Hi! This summer I had several metamorphic American toads and I was wondering if it is possible to know the sex of them. I know for adults it is possible to determine if they are males or females according to the colour of their throats, presence of nuptial pads, and/or if they make calls. When is the earliest that these metrics can be used? Do they have to be reproductively mature? If so, are there any other tricks for determining the sex of young toads (or even tadpoles)?
    I have pictures of all of them. Any help would be greatly appreciated!
    Thanks in advance

    They're just too tiny and young to sex at that age. I can usually start to get a rough idea of what an American toad's sex once they're a little over an inch long. It's still really hard to, though.

    Thank you for your reply! I suspected that would be the case... I released mine when they completed metamorphosis, but I would like to rear them for longer next season. Hopefully then I will be able to determine their sex. Have you had experience with raising them from tadpoles in the past? I am looking for any husbandry tips. I know what adult American toads need, but they seem so sensitive and tiny after metamorphosis so I want to make sure I can provide them with everything they need.
    Thanks in advance!
