Also known as yamakagashi, or Japanese water snake, this species is found mostly in Eastern Asia. It is small, rarely exceeding one metre in length, and very shy, so much in fact that they were considered to be harmless for a long time, until someone died of a yamakagashi bite in the 80s. Fortunately, due to their docile temperament, these snakes are very unlikely to bite and fatalities remain exceedingly uncommon. Also, since their venomous fangs are located in the rear of the jaws, they can't inject their venom as easily as other snakes. They feed mostly on frogs and toads. Other than their bright colors, Tiger Keelbacks look kind of normal; however, they have a very interesting defence mechanism. Recently, it was discovered that these snakes feed on poisonous toads; not only are they immune to the toad's poison, but they can actually "sequester" this poison and store it in a couple glands they have in the neck.
