Open encyclopedia reference
Leioheterodon modestus, also known as the blonde hognose snake or the Madagascan golden hognose, is a species of rear-fanged (opisthoglyphous) snake in the family Pseudoxyrhophiidae (previously considered a subfamily of Colubridae). Leioheterodon are the largest hognose snakes in the world, and L. modestus is endemic to Madagascar. Regarding conservation and population, it is considered a species of least concern.
