Saw two patients with serious hand problems. One lost a hand in childhood, another had problems with hand. Rheumatic pains in hands. And so it is, but this is only half the picture. Scorpions are not strictly spiders but belong to the same natural order of Arachnida and for our purposes are most akin to the Wolf spiders, such as Tarantula.
Spiders are exclusively carnivorous, seizing only live prey.
Each species of spider has its own individual patterns of living, breeding and dying. Yet some value may be found by generalizing within each of the five major groupings. The web spiders wrap their prey to immobilize it and drag it to a different section of the web. Wolf spiders are so called because they go out and hunt down their prey. Thus the web weavers spin and wait for their prey to become entangled in the web.
