Gray Madagascar Frog

Adults up to 100-120 mm, one calling male from Tsaratanana 96 mm. Tibiotarsal articulation can reach the nostril. Hand without webbing, foot completely webbed. Terminal discs of fingers and toes somewhat enlarged. Dorsal skin very granular. Colour dorsally brown with usually indistinct lighter or darker spots and markings. Venter whitish. Males with very distinct femoral glands (small but well visible in females), and a slightly distensible, probably single subgular vocal sac. Similar species: Besides the two other species in this subgenus, a confusion is also possible with Boehmantis microtympanum (which has a smooth skin and enlarged discs of fingers and toes). Juveniles can be mistaken with species in the subgenus Brygoomantis, especially with Mantidactylus biporus and similar species.Taken with permission from Glaw and Vences (2007).

Andavaka, Anjanaharibe, Tsaratanana (Antsahamanara, Antsahamanintsy), Benavony, Besariaka, Marojejy. It occurs between 200-1,000m asl in streams of pristine rainforest (Andreone and Raxworthy 2008).

Habits: Found along small and medium-sized rainforest streams, usually at deep and slow-flowing stretches. Calling males do not aggregate in choruses but may occupy specific territories. During the day and when disturbed, specimens retreat into deep burrows under overhanging slopes at the stream edges. Calls: A loud and short, guttural, pulsed note, repeated after long and irregular intervals.

It occurs in many protected areas (Andreone and Raxworthy 2008).
