On this our second day in Madagascar, we had already seen quite a few different species of frogs. This one, which was hopping across the road along the edge of Analamazaotra Reserve, was the largest and greenest one yet. But its record didn't last long; about twenty minutes later my sister Mary found an even larger and greener one.

I had originally identified this frog as Boophis sibilans, which I believe was correct at the time. Madagascar frog expert Devin Edmonds later corrected this on iNaturalist to Boophis sandrae, which had not been described yet at the time I took the picture. But later still, Boophis sandrae was split into three groups, and only the ones near Ranomafana now have the right to call themselves B. sandrae (I just bet that goes over well at parties). This one must be from one of the other two groups, either Boophis asquithi or the not-yet-formally-described "B. sp. Ca37", both of which are known from near this area.

Here is a list of all the reptiles and frogs I saw on this 2007 trip to Madagascar.
