Marojejy. Specimens from Andasibe may in fact belong to a differentiated species (Glaw and Vences 2007). It has been recorded from near sea level up to 1300 m asl (Glaw and Vallan 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Calling males were found during the day and evening in the forest leaf litter. Characteristic for this species are the normally extremely slow movements. When disturbed, however, they move faster and can jump up to 20 cm (Glaw and Vences 2007).

Calls: Regular series of chirping notes of very high frequency (Glaw and Vences 2007).

Trends and Threats
A major threat to this species is the receding of its forest habitat due to subsistence agriculture, timber extraction, charcoal manufacture, livestock grazing and expanding human settlements (Glaw and Vallan 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
