What are the two types of coelom development?

The two types of coelom development are schizocoely and enterocoely. Schizocoely occurs when the coelom forms from mesodermal tissue that splits or cavitates, typically seen in protostomes like annelids and mollusks. In contrast, enterocoely involves the formation of the coelom from pouches that bud off the endoderm during embryonic development, characteristic of deuterostomes such as echinoderms and chordates. These developmental pathways reflect fundamental differences in the embryonic development of these two groups of animals.
