Are harmless arachnids cryptic and nocturnal habits of most species. Usually live under logs, stones, leaves and litter, buried or in bromeliads on leaves and stems or roots of living plants, and may also inhabit caves. Are highly diverse and abundant in tropical regions of the world, with 6,476 species (Kury, 2011). Are very sensitive animals that have a high degree of endemism and limited dispersal ability, thus being a group with high potential for extinction. The Neotropics has the largest percentage of the world's wealth of harvestmen (57%) of which 41% are in Brazil (938 species).

多数蜘蛛类节肢动物习性隐秘且夜行。通常栖息于树干、石块、叶片及杂物之下，或在活植物之叶片、茎干或根系上的凤梨科植物中隐藏，亦可能居住于洞穴之中。此类生物种类繁多，数量丰富，尤其在世界的热带地区，据Kury（2011年）统计，已知有6,476种。它们是极为敏感的动物，具有高度的地方特有性和有限的扩散能力，因此构成了一个极具灭绝风险的群体。新热带地区拥有世界上最大的螳螂蛛资源（占57%），其中41%位于巴西（共有938种）。
