A MEXICAN LEOPARD FROG
Passing by a pond emerald green with algae, a leopard frog was spotted a few feet from the bank. On my hikes typically critters fly or jump away before I can unstrap my backpack, bring out the camera and wait for it to hum and click before it can take a picture but this time I did all that and the frog still sat there. I took pictures closer and closer until he filled my entire viewer. You can see the resulting portrait below:
Who knows why this frog didn't jump? He did when he was prodded. Maybe he was a philosopher frog. Anyway, he looks pretty much like the US's Northern Leopard Frogs, except that his body is grayer than I'm used to.
Back at the computer I was shocked to see that leopard frogs have been shifted from the nice genus Rana to the harder-to-remember Lithobates.
Moreover, leopard frog taxonomy is poorly understood, so we'll just call this a leopard frog, genus Lithobates.
