Just wanted to show you one of my first frogs, a Lithobates warszewitschii. I caught him when he was a tadpole and now is a mature male.
A curious fact is that this frog together with the L. vaillanti are the only frogs from the palmipes group that vocalize without having vocal sacs or vocal slits.
Where I found the tadpole
Tadpole
Already with 4 legs
Froglet
Juvenile
Adult
Any question I am glad to help
