[2][3] It is a ground dweller, living mainly in vegetation such as sedges, generally brown, slenderly built and agile, with long, practically unwebbed toes.

Strongylopus grayii is a fairly small species (snout-to-vent length of breeding specimens about 25 to 50 mm).

The facial band extends more or less from the nostril, across the lower part of the eye, rearward over the tympanum, to the base of the fore leg.

The species occurs in Lesotho, South Africa, Eswatini, and possibly Botswana and parts of Namibia.

In the breeding season, its voice is an inoffensive musical click, rather like a drop of water falling into a pond, but when a large chorus is active, such as in sedge around a dam, the effect is like a loud, continuous rattle.

Though the males mainly sing in chorus at night, they may call at any time of the day from concealment, particularly in cloudy weather.
