It seems males and females are not created equal, especially when it comes to venom. Enter the Sydney Funnel Web spider, a hairy and scary looking spider that can be found in the moist cool forest areas of ….you guessed it, Sydney Australia.

Life starts off as an equal playing field (apart from the obvious differences in girl and boy bits) with the venom profiles being the same. They spend the first few years of their lives hanging around close to their burrows, which are usually found under rocks, rotting logs and in leaf litter.
