Scytodidae spiders are haplogyne, meaning they lack hardened female genitalia.

They possess long legs and a dome-shaped cephalothorax, and are usually yellow or light brown with black spots or marks.

[3][4] Scytodidae catch their prey by spitting a fluid that congeals on contact into a venomous and sticky mass.

The spider usually strikes from a distance of 10 to 20 millimetres (0.39 to 0.79 in) and the entire attack sequence only lasts 1/700th of a second.

[6] Some species exhibit presocial behaviour, in which mature spiders live together and assist the young with food.
