Question: what is the difference between a spider and a daddy long legs?
Answer: Spiders, of the order Araneae, have a distinct waist between the cephalothorax and the abdomen. Opilionids have just two eyes, compared to the usual eight in spiders. Daddy longlegs also do not produce silk, unlike spiders. They do not spin webs, and they do not use webs to capture prey.
