Since we broke up the plants into two groups, we decided to break the animal kingdom into two groups. This slide highlights animals called invertebrates. You need to know that there are many more invertebrates in the world than vertebrates. Not only are there greater numbers, but there are also many more species.
Invertebrates include any animal that does not have vertebrae (backbone). Here's a short list of invertebrates:
- Sponges
- Jellyfish
- Sea Anemone
- Worms of all kinds
- Slugs and Snails
- Crustaceans
- Insects
- Spiders
The list goes on and on. There are more insect species than any other group of animals. Vertebrates are limited to fish, amphibians, reptiles, birds, and mammals. Why do vertebrates deserve their own page? They get their own page because we are vertebrates.
