Yeah, but unless you're silly enough to step on it or sit on it, they generally leave you alone. It's not like spiders or snakes have anything to gain from killing you, apart from self defence . . .
Apparently the most dangerous animal in Australia, the one responsible for most hospital admissions & death, is a . . . . horse !
Closely followed by dogs I'd say
Spiders & snakes are WAY down the list
What the hell are you guys doing to horses that makes them want to hurt you? The mind boggles...
