It is a small species of toad: males measure 16.5–23.5 mm (0.65–0.93 in) and females 20.4–30 mm (0.80–1.18 in) in snout–vent length.
When threatened, the toad folds its limbs under its body, tucks its head in and tenses in a ball shape. If on an incline (this is how it gets its name), this causes it to roll down the slope, escaping the attention of its predator, and looking like a dislodged pebble. Its cryptic black and dark grey coloring that may appear as dark navy blue to some blends with its sandstone habitat.
