Taiwan Tiger Keelback (Rhabdophis tigrinus formosanus), family Colubridae, Taiwan
Mildly to moderately venomous.
Venom is excreted into the saliva, and enters the prey through the bite wound. Keelbacks do not have fangs.
This species is also poisonous! They sequester toxins from the toads they prey on.
Some herpetologists consider this to be a distinct species, R. formosanus.
