difference between Arthropoda and Annelida
Answers
Answer:
difference Between arthropoda and annelida is :-
Annelida and Arthropoda are two phyla of the kingdom Animalia. Both Annelida and Arthropoda are composed of segmented animals. The main difference between Annelid and Arthropoda is that Annelida consists of a hydrostatic skeleton whereas Arthropoda consists of an exoskeleton made up of chitin. Animals in both phyla are subdivided into different classes based on their diversity. The three classes of the phylum Annelida are Polychaeta (marine bristle worms), Oligochaeta (aquatic and terrestrial earthworms) and Hirudinea (leeches). The five classes of the phylum Arthropoda are Crustacea (shrimp, crayfish, and lobster), Arachnida (spiders, ticks, mites and scorpions), Chilopoda (centipedes), Diplopoda (millipedes) and Insecta (bees, butterflies, roaches and beetles).

Explanation:
Annelida :
Symmetry - Bilateral
Coelom - Eucoelomate
Segmentation - Present
Digestive System - Complete , Extracellular
Respiratory System - Absent , Aerobic Respiration through skin , gills or parapodia.
Circulatory system - Closed type
