Invertebrates

Invertebrates are animals that do not have a backbone. About 97% of all animal species are invertebrates.

Examples: Insects, arachnids, and molluscs.

💡 Fun Facts

  • Insects: Have an external skeleton (exoskeleton) and six legs.
  • Arachnids: Unlike insects, arachnids (like spiders) have eight legs and two main body parts.
  • Molluscs: A soft-bodied group that includes everything from snails to the giant squid, which has eyes as big as dinner plates!
  • The octopus, a mollusc, is thought to be the most intelligent invertebrate, capable of solving complex puzzles, using tools, and even escaping from aquariums.
  • The phylum (a major group) of insects and other arthropods is the largest in the animal kingdom, with over a million described species.
