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.
