Open encyclopedia reference
Glyphoglossus volzi, also known as Sumatra squat frog, is a species of frog in the family Microhylidae. It is endemic to Sumatra, Indonesia. The specific name volzi honours Dr Walter Volz, a Swiss zoologist and traveller.
Glyphoglossus volzi is a poorly known species occurring in lowland primary forest at elevations of 50–980 m (160–3,220 ft) above sea level. It is only known from few specimens, but this likely reflects the lack of suitable sampling methods for what is likely a fossorial species. It probably lays its eggs in pools of standing water on the forest floor. The main threat to this species is clear-cutting of lowland tropical rainforest for oil palm plantations, small-holder agriculture, and wood extraction. It is present in the Bukit Barisan Selatan National Park and may be present in other protected areas.
