Perhaps you have heard that "the daddy-longlegs is the most poisonous spider, but it can’t harm humans because its mouth is too small."

Although this comment sounds interesting, it is false.

Daddy-longlegs (also called harvestmen) have eight legs like other arachnids, but they are not true spiders. True spiders have two body parts and eight eyes. Daddy-longlegs have one body part and two eyes.

You will never find a daddy-longlegs spinning a web because they cannot make silk. Also, daddy-longlegs eat decomposing plants and animals since they have no fangs, no venom glands and no other way to attack prey.
