What distinguishes true spiders in Order Araneae?
Answer
Two-part body connected by a pedicel and silk production
The Order Araneae is reserved for true spiders, identified by a highly specific anatomy: a body divided into two main parts—the cephalothorax and the abdomen—which are visibly joined by a narrow constriction known as the pedicel. Crucially, members of this order also possess specialized spinnerets located on the abdomen used for producing silk, a biological function central to their classification, regardless of whether they build complex webs or use silk primarily for retreats.
