@stueytheround In Australia, there are several spiders whose venom is considered medically significant due to their potential to cause harm to humans. Some of the most notable Australian spiders with venom that can be dangerous to humans include: 1. Sydney Funnel-web Spider : These spiders are known for their highly toxic venom, which can cause serious symptoms if bitten, including muscle spasms, sweating, nausea, vomiting, and potentially life-threatening complications. 2. Redback Spider : The redback spider is related to the black widow spider and has venom that can cause severe pain, sweating, muscle weakness, and other symptoms in humans. Bites from redback spiders can be dangerous, especially for children or individuals with compromised health. 3. Mouse Spider : Mouse spiders are another group of spiders in Australia with venom that can cause medical issues in humans. While less common than some other venomous spiders, their bites can result in symptoms such as localized pain, nausea, and headache. 4. White-tailed Spider : While the white-tailed spider's bite may not be as toxic as some others on this list, it can still cause local pain, redness, and ulceration at the bite site. In some cases, systemic symptoms like nausea and malaise can occur. It is essential to seek medical attention if bitten by a spider in Australia, especially if you suspect it may be one of the species mentioned above or if you experience severe symptoms following a bite.
