With around 120 species and 18 genera, the crevice weavers are found all over the world. Their silk-spinning organ, cribellum, is similar to primitive spiders.
Size: Female spiders are around 0.78 in (1.9 cm), and males are much smaller being about 0.39 in (0.99 cm).
Color: Females have dark brown body while males are lighter in color. The dorsal carapace of male spiders is streaked with dark shades.
Other Characteristic Features: Male spiders have longer legs than female crevice weaver spiders. The palps of the male spiders look like unicorn-horns.
Eggs are deposited inside a silk sac, guarded by the mother spider.
Spiderlings are known for their social deportment. They are firmly attached to their siblings and stay together for a long time until they are ready to lead a life on their own.
Crevice weavers are known for their funnel-shaped web.
They might be venomous for their preys but not for humans. If bitten, individuals can experience swelling, uneasiness, and allergy, but it is unlikely to cause any danger.
