Also known as the Asian black-spined toad, Asian toad, black-spectacled toad, common Sunda toad, and Javanese toad.
A very common animal in Hong Kong, often found hopping around at night, and buried under leaves during the day, and sometimes found in quite dry places.
Toads have dry, warty skin, and this one has two large parotoid glands which can secrete a toxic fluid, which deters most predators. Not all, as Cobras, and Red-neck snakes both eat these with relish (I mean, avidly, not with a side of sauce).
These animals are carnivorous, and feed by flicking out their sticky tongue.
