Be Wary of Spider Bites!

22 July 2011
For macro and nature enthusiasts, many understand that spiders have their own store of venom for hunting purposes. But what many don’t know of each spider, is the propensity to bite a human and the effect of the venom on humans.

Most spiders contain amounts of venom too small to really affect a human being. Most also do not go biting a human unless provoked. But that doesn’t mean you should go sticking your fingers at any spider you see. (but if you do, please tell me how much it hurt) ūüėČ

Today, I did some close ups on the fangs of what looked like a Sac Spider. The sac spider’s venom contains a cytotoxin, which means that it poisons or kills cells. The bite would typically give a stinging sensation, and heard to be very painful. The effect of the bite may vary from person to person, from redness, to swells, and even blisters that take weeks to heal. For the record, sac spiders do not build webs but a silk tube or sac which it hides in – hence the name.

The alleged sac spider dropped on me while I was fumbling with my camera. Luckily for me, it didn’t leave me any souvenir except for a couple of photos.

Ground Spider (Cryptothele sundaica) - DSC_0445#11 Quite skittish, it moved every time I fired a shot. Disturbed by the flash I suppose.

Ground Spider (Cryptothele sundaica) - DSC_0457#15 Lovely pose, but the eyes were out of focus! No chance to retake as it moved after every shot.
