Spider Quiz #4

Spiders are insects: FALSE

Spiders are not insects. They are arachnids. They are related to insects in that they are both arthropods–these animals have a segmented body, jointed and usually a hard exoskeleton that is shed when molting.

Spiders have

  • 2 body parts
  • 8 legs
  • a pair of pedipalps (these help them maneuver prey into their mouth and in males, transfer sperm to females)
  • can produce silk from 4-6 spinnerets.
  • have fangs to inject venom into their prey.

A daddy-long-legs is NOT a spider! Because it has only ONE body part, does not have fangs, does not produce silk and does not have venom. Daddy-long legs belong to a group of animals called Harvestmen.

Ticks and mites are also not spiders, though these also have 8 legs.

Insects on the other hand have 3 body parts, 6 legs and go through incomplete or complete metamorphosis before becoming an adult.

Both spiders and insects grow through a process called molting, which is shedding their skin.
