Exploring Vertebrates and Invertebrates

What are three main characteristics of vertebrates?

• Gills, segmented body, soft tissue skeleton

• Backbone, complex nervous system, skeleton made of bone or cartilage.

• Cold-blooded, no backbone, external skeleton

• Lungs, simple nervous system, exoskeleton

List two characteristics that define invertebrates.

• 1. Lack of a backbone. 2. Generally simpler body structure.

• Warm-blooded organisms

• Complex body structure

• Possess a backbone

Name one example of a class of vertebrates.

• Amphibians

• Mammals

• Insects

• Reptiles

What is one key difference between vertebrates and invertebrates?

• Invertebrates have a skeleton; vertebrates do not.

• Vertebrates are cold-blooded; invertebrates are warm-blooded.

• Vertebrates can fly; invertebrates cannot.

• Vertebrates have a backbone; invertebrates do not.

How do vertebrates typically differ in terms of body structure compared to invertebrates?

• Invertebrates have a backbone and more complex body structures.

• Vertebrates lack a nervous system while invertebrates have one.

• Vertebrates have a backbone and more complex body structures, while invertebrates do not.

• Invertebrates are typically larger than vertebrates.
