Gastrophryne mazatlanensis — Mazatlan Narrow-mouthed Toad
This species was previously considered a subspecies of Gastrophryne olivacea.
While my car mates were photographing a Mexican Leaf Frog that Rob and Nicholas Kreutzer had found earlier, I wandered away, looking for movement in the puddles that lined the road. This weird little frog caught my eye, but I only got this one partly-obscured photo before it dove down into the muck. I tried to dig it out in order to show it to the others, but got nothing but a muck-covered hand for my troubles.
A few days later, Andrew DuBois spotted another of these oddballs while we were (once again) photographing Mexican Leaf Frogs at the side of the road.
My third and final narrow-mouthed toad of the trip was under a hunk of crumpled ground cloth in an abandoned greenhouse on the grounds of the Álamos hotel in which we were staying. This time there were no Mexican Leaf Frogs involved.
