im a reptile expert i no nothing about spiders but by the looks of that its seems to be a white tailed spider so go get your friend some help!!. if your unsure you should remember the golden rule...TREAT EVERY BITE AS POISIONOUS!!!
It's a jumping spider of sorts, don't worry your leg won't fall off with these don't worry about doc unless your friend starts to have any reactions like sweating around bite sight etc
Little while ago there was huge upset about people guessing i.d of snakes (for good reason, misidentifying snakes can cause problems)...might want to apply the same rule to spiders?
On the topic of deadly spiders, anyone know what this guy is, I'm thinking some sort of orb weaver...
Pretty poor photo, I was going to get a better one then this baby monitor ran next to the car so I put the spider down to see this monitor but they both got away
