Differences Between Annelids and Arthropods
The major difference between annelids and arthropods is given below:
Difference | Annelids | Arthropods |
---|---|---|
Body Structure | Segmented body with internal organs | Segmented body with chitinous exoskeleton |
Respiratory System | Primarily rely on skin or gills for respiration | Possess diverse respiratory organs like gills, book lungs, or tracheal systems |
Appendages | Lack jointed appendages | Have jointed appendages for movement |
Circulatory System | Closed circulatory system with blood vessels | Open circulatory system with hemolymph |
Reproductive Methods | Mostly monoecious, some dioecious | Mostly dioecious, with internal fertilization |
Habitat | Found in diverse habitats like soil, freshwater, and marine environments | Inhabit a wide range of environments, including terrestrial, aquatic, and aerial habitats |
Phylum Arthropoda
Phylum Arthropoda is the largest phylum in the Kingdom Animalia and it includes insects. Arthropoda makes up more than two-thirds of all known species worldwide. The phylum Arthropoda characteristics include jointed appendages, a well-organized body structure with a segmented design, and a tough exoskeleton made of chitin. The Arthropoda body is divided into three sections: head, thorax, and abdomen.
The Phylum Arthropoda examples include insects such as ants, and butterflies arachnids like spiders and scorpions, crustaceans such as crabs, lobsters, and shrimp, as well as myriapods including centipedes and millipedes. In this article, we will cover the Phylum Arthropoda and its classification, and characteristics in detail.
