Red Bellied Black Snake (Pseudechis Porphyriacus).
Red bellys have a fearsome reputation amongst the public in Australia but they're actually very timid snakes and would much prefer to run away than sink their fangs into you. Whilst their venom is quite potent, no deaths can be directly attributed to red bellied black snake bites. Having said that, the symptoms are apparently so unpleasant that a bite victim may wish that they were dead. - EnigmaTech
