Rather reluctant to the presence of man, the Interior Taipan is nevertheless one of the most poisonous snakes in the world : one bite of it could contain enough venom to kill one hundred adult men.
Its habitat is the arid alluvial plain: the absence of rain typical of this type of landscape causes cracks in the clayey soil, and it is precisely here that this snake creeps and lives. It can measure up to two and a half meters, has a whip tail and is covered with very shiny scales. Its bite causes nausea, headache, abdominal pain, diarrhea, up to paralysis or suffocation.

It measures up to six meters, has a tapered body and pointed tail, a flattened head and two occipital scales on the nape. Before biting, the king cobra emits a hiss : in this case it is advisable to move away promptly but with not too fast or nervous movements. The bite is particularly painful and its venom attacks the nervous system.
