Yes, the IUZN has listed them as endangered:
Agalychnis annae (Blue-sided Treefrog)

And they are protected by the CITES regulations. => In the European Union, you need a Certificate of Origin for you animals and shipping them across EU boarders is probably a lot of (CITES) paperwork.

But, as I mentioned before: They have been bred in the US in the last couple of years => there should be a stock of A. annae in the US. So, take care of this stock, that this species does not get lost again.
