Anja Community Reserve, Fianarantsoa province, MadagascarApril 27, 2007
Mascarene Ridged Frog (Ptychadena mascareniensis)
I was all excited to see this attractive frog, at that time a new species for me. It was not very cooperative, and could leap prodigiously, and we chased it around for a long time before it finally settled down long enough for a few photos. Later I discovered that it is by far the most common and widespread frog in Madagascar, and we saw dozens and dozens of them.

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

Ranomafana National Park, Fianarantsoa province, MadagascarApril 27, 2007
Mascarene Ridged Frog (Ptychadena mascareniensis)
This was the second in the soon-to-be-vast set of these frogs that we saw throughout Madagascar.
Chez Arol grounds, Masoala National Park, Toamasina province, MadagascarMay 1, 2007
Mascarene Ridged Frog (Ptychadena mascareniensis)
These frogs were abundant on the grounds of Chez Arol.
Anjajavy, Mahajanga province, MadagascarMay 7, 2007
Mascarene Ridged Frog (Ptychadena mascareniensis)
The garden pond at Anjajavy at night was filled with and surrounded by three types of frogs: small Boophis doulioti treefrogs, toad-like Tomopterna labrosa, and a few of these more typical frogs. The ones here looked a little different than ones we had seen elsewhere, and in particular some of them (like this one) had prominently green dorsal stripes. I hadn't found any mention of green dorsal stripes on this species until after my trip, when the third edition of Glaw and Vences was finally published. That book mentions the occasional green stripe and includes a photo of a green-striped individual.
