Araneomorphae

Sign in to save

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.
