Aggressive in nature and potent in venom, the Sydney funnel-web spider matches the phrase "deadly combination". Mostly found in Eastern Australia near Sydney, these spiders are extremely aggressive when threatened and bite multiple times. They get their name from their funnel-shaped webs where they wait for their prey. They contain potent neurotoxins that can lead to symptoms such as breathing difficulties, muscle spasms and even cardiac arrest. Until the 1980s when the antivenom to their bite was introduced, these spiders led to many deaths per year.

Brown recluse spiders, commonly known as fiddle back or violin spiders are mostly found in the south-central and midwestern United States.

Rather than normal webs, they make irregular flat webs and their bite can cause inflammation, cell death and inflammation of veins and arteries.

Commonly found in Australia, redback spiders rarely leave their webs and thus you can only get bitten if a body part makes contact with their web.
