''Rhabdophis'' is a genus of snakes, generally called keelback snakes, found primarily in southeast Asia. While the term "poisonous snake" is often used for a wide variety of venomous snakes, some species of ''Rhabdophis'' are in fact poisonous. While both venom and poison are toxins, a venom requires direct delivery — for instance intravenously through a snake bite — but can be ingested without harm. A poison can also be absorbed indirectly, e.g. by touch or through the digestive system.〔http://www.telegraph.co.uk/culture/qi/7995002/QI-Quite-Interesting-facts-about-deadly-poisons.html〕 == Species == * ''Rhabdophis adleri'' * ''Rhabdophis angeli'' * ''Rhabdophis auriculata'' * ''Rhabdophis barbouri'', Barbour's water snake〔Beolens B, Watkins M, Grayson M. 2011.
