Grab yourself a dissecting scope; put the tadpole, bellyup, in a dish under the scope. Get a good look inside the tadpoles mouth, and compare it to a species key for frog tadpoles. The number/formation of the teeth will tell you what species of frog your tadpole will turn into.
The frog in general, no. There are several frog species that are endangered, however.
Bullfrog Barking Tree Frog
Depends on the species and how big the frog is.
I don't know but I can tell you that the water-holding frog isn't 1 of those species endangered. Scientists have researched and gone in to more detail about them but they are no threat to be endangered.
There are 17 species of the green tree frog.
There are nearly 5000 species of frogs.
It will vary from species to species. A frog's poop should be shaped like the frog's inner parts and it should be solid.
It depends on the species. For most though, the males have larger toe pads and the female is larger. It is very hard to tell sometimes.
You did not say which species of frog so I will tell you of one particular frog. The southern cricket frog of South-eastern borth America can lay as many as 250 in ditches and ponds. Most species of frogs can lay hundreds of eggs at a time.
Yes it is.
