again not for the faint hearted or weak stomached you have been warned.

This is a mans hand after a bite from a brown recluse spider Loxosceles reclusa its from the US, and its not pleasent but amazing at the damage a little spider can do, im not sure the time frame of these photos but its pretty horrific, heres a bit about and a pic of the spider in question

And here's me eating Strawberry and Apple charlotte and ice cream looking at them lol

[Simon]

lovely pics hey Mary lol

[Mary]

yes they are when you are reading this and finishing your tea lol

[PhilR]

Got to love that necrotising venom :D

(Thanks for putting up a warning in the thread title Simon :))

[sammyp]

Yeah, I'm having peanut butter sandwiches with mine :D

Pretty nasty stuff. I'd be interested to see comparative pictures of a south african sicarius bite, but there don't appear to be any on (photographic) record.

experiments done on rabbits with sicarius venom produced some horrible results though, massive local tissue damage and haemorrhaging (sp) in several internal organs and ultimately (of course) death. :(

[Elsa]

poor rabbits

[Huk7]

Some great pics though Simon.

He was lucky that the necrosis remained localised and ultimetely keeping the finger, I wonder if he had any permanent neruovascular deficit afterwards?

Do you have a link to the document by any chance?

[sammyp]

I'll have to try and track it down again...

[PhilR]

Loxosceles and Sicarius belong to the same clade if I recall, so it's not surprising that they both possess similar necrotising venom.

[sammyp]

Hey, this is the link. I couldn't get it to open on my browser now, but I did read it recently, so maybe it's just my comp ??

[PhilR]

Just looked it up, and they're both Genera of the Family Sicariidae, so my memory didn't fail me on this occasion :D

Nice pics here (http://www.museums.org.za/bio/spiderweb/sicariid.htm) :)

Doesn't work on mine either Sam.

[sammyp]

Yah, lovely little critters. My first road trip when i get back to SA will be to find some of these.... :D

@ Phil: Maybe it's just the site? Very annoying as I've viewed it in the past week...

[PhilR]

Rather you than me :D

[sammyp]

Come on, where's your sense of adventure... :D ?

[Becky]

LOL u 2!

Keep your fingers out the way then Sammy :P

[PhilR]

Come on, where's your sense of adventure... :D ?

Adventure? Sorry, can't find it :p

Just dug this up on another medical site:

Venom of a six-eyed crab spider, Sicarius testaceus (Purcell, 1908), causes necrotic and haemorrhagic lesions in the rabbit.

* Van Aswegen G,
* Van Rooyen JM,
* Van der Nest DG,
* Veldman FJ,
* De Villiers TH,
* Oberholzer G.

Department of Anatomy, Potchefstroom University, South Africa.

By employing haematological, histological and isotope studies on rabbit, it was shown that envenomation by the South African crab spider, Sicarius testaceus, results in tissue necrosis and a marked increase in the permeability of the blood vessels in the vicinity of envenomation. The venom also acts systemically, which results in petechial bleeding of some viscera, thrombocytopaenia and elevated fibrinogen levels. Rabbit envenomation by this species results in a dramatic drop of the platelet count, without haemolytic anaemia. Should these parameters be the same in humans, they may serve as a yardstick to distinguish presumptive S. testaceus envenomation from that of Loxosceles.

Honestly, is there something wrong with people who spend this much time digging around in cyber-space for horrible bite reports.... :P

(Points finger at self.....)

Good luck finding them,

[sammyp]

Cheers mate.


btw, that liink seems to be working again this morning.

[PhilR]

I have read that rabbit paper in its entirety now Sam. Very interesting :)

The site is working for me this morning too!

[Tegenaria]

oh man thats bad! And theres folks over on AB who keep these things as pets!

[Sonny]

told you brown recluse bites make the meat go manky and horrid didnt i?
them pics are cool but his finger is grose.
sonny

[theridiida]

well, sadly that's the nature of their necrotoxin, sonny! it causes necrosis of the flesh & leaves big bad scars.

[Simon]

tissue killing venoms are always pleasent:shocked:

[busybee]

And here's me eating Strawberry and Apple charlotte and ice cream looking at them lol

Mary you are a scream !!!!!!! I was feeling down but now you have cheered me up... cant stop chortling hahahahahaha

[buthus]

I just think people on these invert forums should stop linking to these sensational and very questionable bite stories.

what do you think it is?? there was no story behind it when I found the pics on another forum, I just believed what it said and reposted, a bit naive perhaps??

It could be from a recluse bite, but it could be from something else. The problem is that these and a few other very graphic images found online have become synonymous with the "scary and deadly" brown recluse spider. There is no proof that these wounds were caused by the bite of a recluse spider or any spider for that matter. Are these images even real? They sorta look real, so how much of the story is true?
It becomes yellow journalism about pseudo-science all wrapped up and substantiated when the people that are into this stuff (read...us) link to it and give it more credit than deserved.

Heres some boring info everyone looking at those images should be required to read...

Oh the pictures are definitely real, I have seen more than my fair share of wounds and can recognise the various parts of the wound along with both the necrotising and healing indicators.

But I fully agree with you that a lot are associated with spider bites with absolutely no supporting evidence, just supposition, whereas in reality, necrotising wounds like this can range from a scratch to an underlying pathological condition with everything, including spider bites, in between.

You understand my point perfectly. ;)
