Herpetofauna (1): Common Frog

We spotted this little chap (1-2 long cm) hopping through the undergrowth
at WWT Llanelli ten days ago.

I think he is a young but fully developed Common Frog,
with his pointed snout
and barred hind legs.

I wondered at what point a froglet becomes a frog.
My understanding is that the amphibian can be called a frog
once the tail has been reabsorbed,
i.e. once apoptosis has taken place.

A blown-up image,
to help with identification!
