What is the significance of coelom in the classification of animals?
The presence or absence of a coelom (body cavity) is a key characteristic in the classification of animals. Animals can be categorized as acoelomates (no body cavity), pseudocoelomates (body cavity between mesoderm and endoderm), or coelomates (body cavity within mesoderm). This classification is important in understanding the evolutionary relationships and anatomical differences among animal groups.
