What key morphological tools define the Order Araneae members like wolf spiders?
Answer
Chelicerae modified into fangs and spinnerets
The Order Araneae encompasses all true spiders, and members are defined by specific apparatuses. Key defining characteristics include the presence of chelicerae which are modified into fangs, often used for venom delivery, and the presence of spinnerets located towards the posterior end of the abdomen, which are used for producing silk. These features separate them clearly from other arachnids, such as harvestmen or scorpions. While wolf spiders use spinnerets, their behavioral distinction within Araneae is their cursorial hunting style rather than relying on a capture web.
