Araneomorphae
The Araneomorphae (also called the Labidognatha or "true spiders") are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to those of Mygalomorphae (tarantulas and their close kin), which point straight down. Araneomorphs comprise the vast majority (about 92%) of living spiders.

The Araneomorphae (also called the Labidognatha or "true spiders") are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to those of Mygalomorphae (tarantulas and their close kin), which point straight down. Araneomorphs comprise the vast majority (about 92%) of living spiders.
== Distinguishing characteristics == Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations that they can employ during prey-capture. They have fewer book lungs (when present) – usually one pair – and the females typically live one year.
