What is the Difference Between Arthropods and Annelids?
🆚 Go to Comparative Table 🆚Annelids and arthropods are two distinct types of invertebrate organisms with different characteristics. Here are the main differences between them:
- Body Structure: Annelids have a segmented body, while arthropods have an exoskeleton and a segmented body with paired jointed appendages.
- Segmentation: Annelids have complete metameric segmentation from head to tail, while arthropods have incomplete metameric segmentation.
- Circulatory System: Annelids have a closed circulatory system, while arthropods have an open circulatory system.
- Breathing: Annelids breathe through their skin, while arthropods breathe through trachea, gill, book lungs, etc..
- Reproduction: Most annelids are hermaphrodites, meaning they have both male and female reproductive organs in the same body, and they reproduce both sexually and asexually. Arthropods, on the other hand, have separate sexes.
- Examples: Examples of annelids include earthworms and leeches, while examples of arthropods include prawns and cockroaches.
Despite these differences, both annelids and arthropods are considered highly successful organisms on Earth, playing crucial roles in various ecosystems.

Comparative Table: Arthropods vs Annelids
Here is a table highlighting the differences between arthropods and annelids:
Feature | Arthropods | Annelids |
---|---|---|
Segmentation | Incomplete metameric segmentation | Complete metameric segmentation from head to tail |
Exoskeleton | Present | Absent |
Appendages | Paired jointed appendages | Unjointed and jointed appendages |
Circulatory System | Open circulatory system | Closed circulatory system |
Respiration | Tracheae and book lungs | Respire through their body surface |
Excretory Organs | Malpighian tubules | Nephridia |
Reproduction | Sexual | Hermaphroditic |
Examples | Prawn and cockroach | Earthworms and leeches |
Arthropods are characterized by an exoskeleton, a segmented body, and paired jointed appendages. They include insects, arachnids, myriapods, and crustaceans. Annelids, also known as ringed worms or segmented worms, are a large phylum that includes ragworms, earthworms, and leeches.
