We have been seeing a few black snakes around our yard this spring, particularly as the  creek has been drying up and the snakes have had t move further afield to find water and food. It's good to know that blacks aren't terribly venomous and they keep the more toxic browns away.

Red Bellied Black Snake

The Red Belly Black Snake ( Pseudechis porphyriacus ) is one of our best known elapid (or front fanged venomous) snakes. It is wide spread throughout the Eastern Parts of Australia, preferring to live near creeks, and fixed water sources. Their diet consists mostly of frogs, although they are known to eat the occasional lizard, and smaller snakes. Although they are venomous, and are classified as dangerously venomous, the toxicity is not considered fatally dangerous. The venom of this genus destroys muscle tissue, but does not effect the central nervous system. Few human deaths have resulted from a bite from this species, and no adults have died from a bite. 

They are excessively shy creatures, who will evade humans rather then strike. Its also a fact that if you have red bellies in your yard, you are not likely to have Brown snakes! Red's actively chase Brown's away, as the Red Belly toxin kills Browns.

* Given that stat, you will be amazed to hear (according the Bureau of Statistics) that you are more likely to be struck by lightening or die of a bee sting then you are of a snake bite.

* From the same source, between 70 – 93 % of snake bites are received while trying to capture or kill a snake.

* There has only ever been one recorded death from a red bellied black snake bite, and that occurred in the 1800's on a new born infant. Their venom does not work that way.

* Red Bellied Black Snakes will actively chase and kill Eastern Brown snakes from their preferred locations. (Brown Snakes are responsible for around 65% of the deaths by snake bite in Australia) This makes Red Bellies good to have around!
