Spider. A spider is a software program that travels the Web (hence the name spider), locating and indexing websites for search engines.
Spiders are small (with the exception of the Acromantula) eight-legged and eight-eyed creatures. They are very common and come in many species, varying from region to region; all are carnivorous and some are venomous, but for the most part they are relatively harmless and can sometimes be used as a potion ingredient.
