Question:

What is the difference between vertebrates and invertebrates?

Answer:

Vertebrates have a backbone and a complex skeleton, while invertebrates don’t. Vertebrates are usually bigger and more advanced, while invertebrates include smaller and simpler animals.

Key Points

  • Vertebrates: Backbone present, advanced organ systems (e.g., mammals, birds, fish).
  • Invertebrates: No backbone, simpler body structure (e.g., insects, worms, jellyfish).
  • Percentage: 95% of animals are invertebrates.
