How Dangerous are the Australian Wolf Spiders?

Australian Wolf Spiders have a reputation for being venomous. They are listed as one of the most dangerous spiders in the world. But how harmful are they?

Effects on Humans

According to WebMD, Australian Wolf Spiders are not considered highly dangerous to humans. However, since they are big, their bite can be painful. Their venom may cause mild to moderate symptoms such as swelling, redness, and itching. 

Effects on Prey

However, the Australian Wolf Spider’s venom is much more potent for its prey. It paralyzes and pre-digests the insects and other small creatures it hunts, making it easier for the spider to eat them. This venom is a crucial adaptation for its hunting lifestyle.
