This animal is caught in a pond near my apartment.

Isn't it so cute?

First it was swimming by its tails but now it started to have legs.

 Hmmmm..... this is a tadpole!

 What species of a frog would this be?

Well, I think I will not be a toad or a salamander, but I'm quite sure that it is a tree frog.

I hope that it is not a bull frog tadpole! 

 I will release them in a few days.
