I am a frog

Busy sort of morning - we were sorting out the filter on the pond and getting ready to put in the waterfall.  We disturbed a few frogs in the process and stirred up the water.  I took this frog after lunch as he was basking on a lily leaf.  When i reviewed him I though he looked a bit like a snake but he is definitely a frog.  
Dull morning but sunny  warm afternoon
