Oreophrynella nigra (common name: pebble toad) is a species of toad in the Bufonidae family. It is found in Venezuela and possibly Guyana. Its natural habitats are subtropical or tropical moist montane regions and swamps.
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 causes it to roll down the slope, escaping the attention of its predator, and looking like a tumbling pebble. Its cryptic black and dark grey coloring that may appear as dark navy blue to some blends with its sandstone habitat. This toad was featured on the BBC series, Life, pursued by a tarantula. It is a very small specie of toad; about an inch in length.
