Red-necked Keelback For Sale

Rhabdophis subminiatus

The Red-necked Keelback (Rhabdophis subminiatus) is a fascinating semi-aquatic frog-hunter of Thai rice paddies that sequesters toxins from the toads it eats into specialised nuchal glands. Rear-fanged and capable of severe coagulopathy, it flattens its neck to flash warning colour when threatened. A genuinely interesting species, but not one for beginners.
