|Giant desert centipede
Are all insects bigger in the desert? Maybe not, but it sometimes seems that way, and when you see a giant desert centipede slithering along, it certainly seems bigger than its 6 3/4 inches. These segmented arthropods hunt at night, preying on insects, other arthropods and sometimes small lizards. Centipedes are not aggressive, usually trying to get away from humans, however I was bitten by one with no provocation on my part and felt the painful effects for several days afterward. If you are unlucky enough to be bitten, allow the wound to bleed, if possible, then wash with soap and warm water and apply antiseptic. Consult your physician if you do not have an up-to-date tetanus shot.
