Inland taipan may include headache, nausea, vomiting, abdominal pain, diarrhoea, dizziness, collapse or convulsions leading to major organ effects: neurotoxicity, coagulopathy, rhabdomyolysis or renal failure/damage and finally death. Inland taipan snake venom contains potent presynaptic neurotoxins (toxins in venom that cause paralysis or muscle weakness). Also present are postsynaptic neurotoxins, which are less potent but more rapid acting than the presynaptic neurotoxins. Presynaptic neurotoxins disrupt neurotransmitter release from the axon terminal. This takes days to resolve and does not respond to antivenom. Postsynaptic neurotoxins competitively block acetylcholine receptors but the effect can be reversed by antivenom. Neurotoxic envenoming causes a progressive descending
Coastal taipan coastal taipan occurs only in Australia and the island of New Guinea, which comprises two Indonesian provinces on the west side of the island and the nation of Papua New Guinea on the east side of the island. Found in northern and eastern Australia, the coastal taipan, despite its name, can live in habitats hundreds of kilometres away from the nearest beach. Its geographical range extends from north-western Western Australia, the Northern Territory, across Cape York Peninsula and down eastern Queensland into northern New South Wales (as far south as Grafton). However, the coastal taipan is not found in regions
