There seems to be an evolutionary trend towards a reduction in the amount of sticky silk used, leading to its total absence in some species. Our objective in this review was to study about poisonous spiders and find out treatments of them. The ancestral arrangement ("haplogyne" or "non-entelegyne") consists of a single genital opening, leading to two seminal receptacles (spermathecae) in which females store sperm.

Although all arthropods use muscles attached to the inside of the exoskeleton to flex their limbs, spiders and a few other groups still use hydraulic pressure to extend them, a system inherited from their pre-arthropod ancestors. Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom,[2] and spinnerets that extrude silk.
