The Brazilian wandering spider (Phoneutria sp.) is regarded by some as the most dangerous spider in the world. Actually a genus with five known similarly venomous species, it is highly venomous and not reluctant to attack people who appear threatening to it. However, recent studies indicate that it only injects venom in about one-third of its bites and may only inject a small amount in another third. Thus the effects of the bites from this spider can range from only a couple of pin pricks to a full-blown envenomation. The Sydney funnel-web spider apparently injects venom in every bite and may thus in effect be more dangerous — though either spider's venom can lead to a medical emergency.
