Arachne Hentai: Character Profile & Collection

A spider girl with the lower body of a spider. Extra eyes are a common addition. Having spider legs in addition to human legs (e.g. post #1282030) is not enough; the character must have spider legs instead of human legs. For spider-legged girls retaining human legs, use arthropod limbs and extra legs. For monster girls of similar body type but not based on spiders, see centauroid. (Source: Danbooru Wiki)
