The Asian Giant Toad, also widely known as the River Toad, is an impressive, heavyweight amphibian found near fast-flowing forest streams and waterfalls. As the scientific name asper suggests, their skin is exceptionally rough and covered in heavy warts and tubercules. They typically display a dark coloration ranging from deep charcoal grey to muddy brown. This species is sexually dimorphic, with females growing significantly larger than males, often reaching massive sizes that rival other giant toad species.
Notes: Unlike many stagnant-water toads, this species prefers environments with high humidity and access to clean water, simulating a riverbank setting. They are strictly nocturnal predators. Handlers should exercise caution and wear gloves or wash hands thoroughly after contact, as they have large parotoid glands capable of secreting a potent milky white toxin when physically threatened.
Why Source This Species:
Impressive Showpiece: Their sheer size and prehistoric, rugged appearance make them a fantastic display animal for large terrariums or paludariums.
Voracious Appetite: They are bold eaters with a strong feeding response, capable of taking down large prey items, which makes them very engaging for keepers to observe during feeding time.
Robust Constitution: These toads are generally very hardy and adaptable to captivity once established, making them a solid choice for keepers looking for a large-bodied amphibian that is not overly fragile.
