Description and behaviour
It is a small species of toad: males measure and females 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.Habitat and conservation
